Find the slope and the y-intercept of the line.
y= 3/4-1/5x

Answers

Answer 1

Answer:

Slope = -1/5

y-intercept = 3/4

Step-by-step explanation:

Equation of Straight Line in the Form y=mx+c

where m is the Slope and c is the y-intercept.

Answer 2

Answer:

 Slope = -0.400/2.000 = -0.200

 x-intercept = 15/4 = 3.75000

 y-intercept = 15/20 = 3/4 = 0.75000

Step-by-step explanation:

* BE AWARE, THIS ANSWER IS NOT TO BE PLAGERIZED AS IT IS CONSIDERED CHEATING IF THIS IS A TEST OR HOMEWORK QUESTION, MOST LIKELY IT IS* - Purpose is to help understanding of the concept.

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                    y-(3/4-1/5*x)=0

STEP 1:

simplify 1/5

Equation at the end of step 1:

y -(3/4-(1/5• x))  = 0

Step 2:

Simplify 3/4

Equation at the end of step 2:

y-)(3/4-x/5)=0

Step 3:

Calculating the Least Common Multiple :

ind the Least Common Multiple

     The left denominator is :       4

     The right denominator is :       5

       Number of times each prime factor

       appears in the factorization of:

Prime

Factor   Left

Denominator   Right

Denominator   L.C.M = Max

{Left,Right}

2 2 0 2

5 0 1 1

Product of all

Prime Factors  4 5 20

     Least Common Multiple:

     20

Calculating Multipliers :

3.2    Calculate multipliers for the two fractions

   Denote the Least Common Multiple by  L.C.M

   Denote the Left Multiplier by  Left_M

   Denote the Right Multiplier by  Right_M

   Denote the Left Deniminator by  L_Deno

   Denote the Right Multiplier by  R_Deno

  Left_M = L.C.M / L_Deno = 5

  Right_M = L.C.M / R_Deno = 4

Making Equivalent Fractions :

3.3      Rewrite the two fractions into equivalent fractions

Two fractions are called equivalent if they have the same numeric value.

For example :  1/2   and  2/4  are equivalent,  y/(y+1)2   and  (y2+y)/(y+1)3  are equivalent as well.

To calculate equivalent fraction , multiply the Numerator of each fraction, by its respective Multiplier.   L. Mult. • L. Num.      3 • 5

  ——————————————————  =   —————

        L.C.M              20  

  R. Mult. • R. Num.      x • 4

  ——————————————————  =   —————

        L.C.M              20  

Adding fractions that have a common denominator :

3.4       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

3 • 5 - (x • 4)     15 - 4x

———————————————  =  ———————

      20              20  

Equation at the end of step

3

:

      (15 - 4x)

 y -  —————————  = 0

         20    

STEP

4

:

Rewriting the whole as an Equivalent Fraction :

4.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  20  as the denominator :

         y     y • 20

    y =  —  =  ——————

         1       20  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

4.2       Adding up the two equivalent fractions

y • 20 - ((15-4x))     20y + 4x - 15

——————————————————  =  —————————————

        20                  20      

Equation at the end of step

4

:

 20y + 4x - 15

 —————————————  = 0

      20      

STEP

5

:

When a fraction equals zero :

5.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 20y+4x-15

 ————————— • 20 = 0 • 20

    20    

Now, on the left hand side, the  20  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  20y+4x-15  = 0

Equation of a Straight Line

5.2     Solve   20y+4x-15  = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  20y+4x-15  = 0 and calculate its properties

Graph of a Straight Line :

 

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 3/4 so this line "cuts" the y axis at y= 0.75000

 y-intercept = 15/20 = 3/4  =  0.75000

Calculate the X-Intercept :

When y = 0 the value of x is 15/4 Our line therefore "cuts" the x axis at x= 3.75000

 x-intercept = 15/4  =  3.75000

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 0.750 and for x=2.000, the value of y is 0.350. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 0.350 - 0.750 = -0.400 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     = -0.400/2.000 = -0.200

Geometric figure: Straight Line

 Slope = -0.400/2.000 = -0.200

 x-intercept = 15/4 = 3.75000

 y-intercept = 15/20 = 3/4 = 0.75000

The price of Stock A at 9 A.M. was ​$12.41. Since​ then, the price has been increasing at the rate of ​$0.12 each hour. At noon the price of Stock B was ​$13.16. It begins to decrease at the rate of ​$0.14 each hour. If the two rates​ continue, in how many hours will the prices of the two stocks be the​ same?

Answers

Answer:

1.50 Hours

Step-by-step explanation:

Given:

→ The price of Stock A at 9 A.M. was ​$12.41. → Since​ then, the price has been increasing at the rate of ​$0.12 each hour. → At noon the price of Stock B was ​$13.16. → It begins to decrease at the rate of ​$0.14 each hour.

To Find:

If the two rates​ continue, in how many hours will the prices of the two stocks be the​ same?

Solve:

Price of stock A at 9 a.m.= $12.41

The price has been increasing at the rate of ​$0.12 each hour.

Increase in price after 3 hours = 0.12 × 3 = 0.36

Price of Stock A at noon= 12.41+0.36 =12.77

Let n be the no. of hours after which the prices of both the stocks will be same .

So, Increase in price after n hours = 0.12 n

Price of Stock A after n hours = 12.77+0.12 n

Price of stock B = 13.16

The price has been decreasing at the rate of ​$0.14 each hour.

Let n be the no. of hours

So, Increase in price after n hours = 0.14 n

Price of Stock B after n hours =13.16-0.14 n

ATQ

12.77 + 0.12n = 13.16 - 0.14n

-12.77 + 13.16 = 0.12n + 0.14n

0.39 = 0.26n

0.39/0.26 = n

n = 1.50

Hence the prices of the two stocks be the​ same after 1.50 hours after 12 pm .

Eric jog 3 1\4 miles on Monday 5 5\8 miles on Tuesday and 8 miles on Wednesday suppose he continues the pattern for the remainder of the week how far will Eric jog on Friday

Answers

Step-by-step explanation:

first, let's bring everything to the same fraction denominator, which would be 1/8 to cover all.

so, he jogs

3 2/8 miles on Monday

5 5/8 miles on Tuesday

8 0/8 miles on Wednesday

the difference from day to day is

5 5/8 - 3 2/8 = 2 3/8 (subtract the whole numbers and then also the fractional part).

to control :

5 5/8 + 2 3/8 = 7 8/8 = 8

so, he adds every day 2 3/8 miles.

that means in 2 days (from Wednesday to Friday) this will be additional 2×(2 3/8) = 4 6/8 = 4 3/4 miles.

so, he will jog

8 + 4 3/4 = 12 3/4 miles

on Friday.

don't forget, when we write something like 2 3/8. we actuality mean (2 + 3/8). and all rules about handling, transforming and calculating expressions apply.

therefore, e.g

2×(2 3/8) = 2×(2 + 3/8) = 4 + 6/8 = 4 6/8 = 4 3/4

If we drop a rock near the surface of Earth, its velocity increases by 32 feet per second for each second the rock falls. Is the velocity of the rock a linear function of the time since it was dropped?

Answers

The velocity of the rock is the number of feet traveled per second

The velocity of the rock is a linear function of time

How to determine the function?

From the question, we understand that the velocity increases by 32 feet per second for each second

This means that we have the following rates:

Velocity = 0, 32, 64, 96, 128....

Notice that the difference between adjacent numbers is 32.

This means that the velocity changes at a constant rate or slope

Hence, the velocity of the rock is a linear function

Which of the following is the graph of an odd-degree polynomial with a positive lead
coefficient?

(Answer choices are in the image)

Answers

The answer selected should already be the right answer.

An even number of total minimum/maximums indicates an odd-degree polynomial. For example, only the 3rd and 4th graphs are odd-degree because they have four mins/maxes total.

For the polynomial to have a positive leading coefficient, the line must go up in the positive direction. For example, only the 1st and 3rd graphs have a positive leading coefficient because their right-most line is going upwards.

The 3rd graph is the only answer choice with both of these characteristics, making it the right answer.

The third graph is the only one that is an an odd-degree polynomial with a positive lead coefficient.

How to Interpret the graph of a Polynomial?

An even number of total minimums/maximums of the Polynomial is classified as an odd-degree polynomial. Now, we see that only the 3rd and 4th graphs are odd-degree polynomials because they have four total minimums/maximums.

For the polynomial to have a positive leading coefficient, the line must go up in the positive direction. This means that only the 1st and 3rd graphs have a positive leading coefficient due to the fact that their right-most line is going upwards.

Thus, we can say that the third graph is the only one that is an an odd-degree polynomial with a positive lead coefficient.
