Answer:

[tex]a=\dfrac{4x-7}{x}[/tex]

Step-by-step explanation:

The equations of lines are :

y=4x-5 and y=ax+2

From above equations,

4x-5 = ax+2

4x-ax = 5+2

4x-7 = ax

[tex]a=\dfrac{4x-7}{x}[/tex]

So, the value of a is equal to [tex]\dfrac{4x-7}{x}[/tex].

Step-by-step explanation:

A rectangle has vertices A(0, 0), B(0, 9), C(4, 9), and D(4, 0). What is the perimeter of the rectangle

We have to find the length of the sides of the rectangle using the formula below

= √(x2 - x1)² + (y2 - y1)² when given vertices (x1, y1) and (x2, y2)

For side AB

A(0, 0), B(0, 9)

= √(0 - 0)² + (9 - 0)²

= √0 + 81

= √81

= 9 units

For side BC

B(0, 9), C(4, 9)

= √(4 - 0)² + (9 - 9)²

= √4² + 0²

= √16

= 4 units

For side CD

C(4, 9), and D(4, 0)

= √(4 - 4)² + (9 - 0)²

= √0² + 9²

= √81

= 9 units

For side AD

A(0, 0), D(4, 0).

= √(4 - 0)² + (0 - 0)²

= √4² + 0

= √16

= 4 units

We can see than

AB = CD = 9 units

BC = AD = 4 units

The perimeter of a rectangle = 2(L + W)

From the above calculation

Length = 4 units

Width = 9 units

Perimeter = 2(4 + 9) units

= 2 × 13 units

= 26 units

Answer:

340

Step-by-step explanation:

We can see in the sample that 18/50 people bring lunches to school. If we divide 18 by 50 we get 0.36 now we know that 36% of people bring their lunches in the sample. Now we take that number and multiply it by 942.

0.36*942= 339.12 which we can round to 340

Answer:

7680πyd³

Step-by-step explanation:

The formula to calculate the volume of the cylinder is πr² h

Here radius (r) = 16 yd

height (h) = 30 yd

Now

the volume is

= πr²h

= 16² * 30 * π

= 7680 π yd³

Answer:

(x + 5)² + (y - 1)² = 4

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k ) = (- 5, 1) and r = 2, then

(x - (- 5))² + (y - 1)² = 2² , that is

(x + 5)² + (y - 1)² = 4

Answer:

Step-by-step explanation:

hello  :

hello:

note :   an equatin for the circle is : (x-a)²+(y-b)²=r²

when the center is the point : C(a , b) and the  radius  r

use this graph : given two points in this circle  A(-3,1) and B(-7,1)

1) AB/2 = r = 4/2 = 2

2) the midipoint for the segment AB is the center C

a = (-3-7)/2     and  b = (1+1)/2

a= -5   and b= 1  so : C(-5 , 1)

an equation is :  (x+5)²+(y-1)²=2²

An equation that models the considered calorie consumption by Jonathan is y = mx + 6k, where m is the number of calorie per buiscuit, and k is the number of calorie per package of pemmican.

You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

We're specified that:

Let we take:

m = number of calories per buiscuit that Jonathan eats.

Then, for x buiscuits, it would be [tex]m \times x[/tex] calories, or in short [tex]mx[/tex] calories.

Let k = number of calories per package of pemmican, then:

for 6 packages of pemmican, it would be [tex]6 \times k[/tex] calories, or in short [tex]6k[/tex] calories.

Thus, total calories Jonathan consumes = y = calories from x buiscuits + calories from 6 packages of pemmican.

or, we get:

[tex]y = mx + 6k[/tex]

Thus, an equation that models the considered calorie consumption by Jonathan is y = mx + 6k, where m is the number of calorie per buiscuit, and k is the number of calorie per package of pemmican.

Answer:

1921 books remaining.

Step-by-step explanation:

This library is fairly organized, so each shelf only has 14 books. Now with 202 shelves, we multiple the shelves by the amount of books per shelf.

202x14=2,828

Now, with 2828 books in the library before being checked out, we need to find out how many books left after the students came.

2828-907=1,921

The answer is 1,921 books remaining.

UM YES! My favorite is Attack On Titans

Answer:

the volume of the gas used for city driving is 17 gallons

Step-by-step explanation:

Given;

average speed for city driving, v₁ = 17.1 miles per gallon

average speed for highway driving, v₂ = 24.7 miles per gallon

total distance traveled, d = 513 miles

total gallon of gas used, t = 26 gallons

Let the volume of gas used for city driving = x

Also, let the volume used for highway driving = y

x + y = 26 -------- (1)

17.1x + 24.7y = 513   ------------(2)

From equation (1); y = 26 - x

Substitute the value of y in equation (2)

17.1x   +   24.7(26-x)   =  513

17.1x   +   642.2   -    24.7x       =    513

17.1x  -  24.7x  =  513   -   642.2

-7.6x   = -129.2

x = 129.2/7.6

x = 17 gallons

Therefore, the volume of the gas used for city driving is 17 gallons

20t

Step-by-step explanation:

15 is where the boat started so 20t is how much the boat traveled from the origional position of 15

The 20t distance the boat has traveled from its original position.

Given that,

She creates a function f(t)= 20t + 15,

To show how many miles she has traveled f(t) from her mom’s house in Texas after (t) hours have passed.

We have to determine,

Which of the following represents the distance the boat has traveled from its original position.

According to the question,

She creates a function f(t)= 20t + 15 .

To show how many miles she has traveled f(t) from her mom’s house in Texas after (t) hours have passed.

Then,

Her mom’s house in Texas after (t) hours have passed.

The 15 is where the boat started

And 20t is the boat traveled from the original position of 15.

Hence, The 20t distance the boat has traveled from its original position.
