Y=2x-7
Then put the y into the other equation

A plant is already 43 centimeters tall, and it will grow one centimeter every month.
Let H be the plant's height (in centimeters) after M months.
Write an equation relating H to M. Then use this equation to find the plant's height after 21 months.

Answers

Answer:

h=m+43, 66cm

Step-by-step explanation:

For each month, it grows by one centimeter, which is represented by 1m or just m. You also have to add the height it already has, which makes h=m+43. For 21 months, substitute 21 for m to get h=21+43 which simplifies into h=66 cm

the ages of a father and his son are in the ratio 10:3. if the son is 15 years now, how many years will the ratio of their ages be 2:1?​

A poll is given, showing 30% are in favor of a new building project.

If 5 people are chosen at random, what is the probability that exactly 4 of them favor the new building project?

Answers

Answer:

0.02835

Step-by-step explanation:

Let p be the probability who are in favor of the project and q be the probability who are not in favor of the project.

p = 30% = 0.30

q = 1 - p = 1 - 0.30 = 0.70

n = 5, x = 4

Now, by binomial distribution formula:

[tex]P(X=x)=^nC_x \:p^x \:q^{n-x}[/tex]

[tex]\implies P(X=4)=^5C_4\: (0.30)^4\: (0.70)^{5-4}[/tex]

[tex]\implies P(X=4)=5 (0.30)^4 \:(0.70)^{1}[/tex]

[tex]\implies P(X=4)=5 (0.0081) \:(0.70)[/tex]

[tex]\implies P(X=4)=0.02835[/tex]

The probability that exactly 4 of them favor the new building project is 0.02835.

Answers

Answer:

Parallel line: [tex]y=4x+33[/tex]

Perpendicular line: y = [tex]\frac{-1}{4}x-1[/tex]

Step-by-step explanation:

From the given equation [tex]y=4x-2[/tex], the number multiplied by [tex]x[/tex] is the slope of that equation, so the slope is 4 in this case.

Let's use the point slope form in this question:

[tex]{y-y__1}=m({x-x__1})[/tex]

where [tex]{x__1}[/tex] and [tex]y__1[/tex] are the given points in your question:

[tex]{x__1}=-8[/tex]

[tex]{y__1} = 1[/tex]

and m is the slope.


Parallel line:

Since parallel means the same slope as the given equation, we put [tex]m = 4[/tex] first.

[tex]{y-1}=4({x-(-8)})[/tex]

[tex]y=4x+33[/tex]

This is the equation that is parallel to [tex]y=4x-2[/tex] and also passes through [tex](-8,1)[/tex].

Perpendicular line:

Since perpendicular means exactly 90° with the given equation, multiplying their slopes and the product will always be [tex]-1[/tex].

Let's find m first,

[tex]4* m = -1[/tex]

[tex]m = \frac{-1}{4}[/tex]

Now using the same point slope form with the same [tex]x__1[/tex] and [tex]y__1[/tex]:

[tex]{y-y__1}=m({x-x__1})[/tex]

[tex]{y-1}=\frac{-1}{4} ({x-(-8)})[/tex]

[tex]y=\frac{-1}{4}x-1[/tex]

This is the equation that is perpendicular to [tex]y=4x-2[/tex] and also passes through [tex](-8,1)[/tex].

The formula that can be used to determine the future value of an amount with compounding is:

FV = P (1 + r)^nm

Where:

FV = Future value P = Present value R = interest rate / number of compoundingm = number of compoundingN = number of years

Future value with monthly compounding = $2000 x ( 1 + 0.035/12)^(12 x 8) = $2645.18

Future value with continuous compounding =  : A x e^r x N

A= amount e = 2.7182818 N = number of years r = interest rate

1000 x e^0.018 x 8 = $8,145.30

Total = $8,145.30 + $2645.18 = $10,790.48

What is Kristen's balance after 8 years?

Future value with quarterly compounding = 2500 x (1 + 0.012 / 4)^(4 x 8) = $2,751.50

Future value with quarterly compounding = 500 (1 .0225)^(8x4) = $1019.05

Total = $3,770.55

What is Gabriella's balance after 8 years?

$3000 x e^0.032 x 8 = $24,780.42

What is Judy's balance after 8 years?

Future value with exponential increase = 1050 x (1.015)^8 = $1,182.82

Future value with biannual compounding = 1950 x (1 + 0.028/2)^(8 x 2) = $2435.80

Solve these 2 Question. 50 Points + Brainelist​

using simultaneous equation:

2x + 3y = 190

3x + y = 180  * 3

Then:

2x + 3y = 190

9x + 3y = 540

--------------------

-7x = -350

x = 50

Insert this in equation 1 to find value of y:

2x + 3y = 190

2(50) + 3y = 190

3y = 190 - 100

3y = 90

y = 30

→ (x + 2)³

[tex]\sf apply \ cubic \ formula : \bold{\left(a+b\right)^3=a^3+3a^2b+3ab^2+b^3}[/tex]

[tex]\rightarrow \sf 125+150+60+8[/tex]

[tex]\rightarrow \sf 343[/tex]

Answer:

(a) x=50 y=30

Step-by-step explanation for (a):

First use system of equations. Isolate a variable and substitute.

2x + 3y = 190

3x + y = 180

Isolate

subtract 3x from both sides of the second equation

y = 180 - 3x

since 180 - 3x = y, you can substitute this into the first equation for y

Substitute

2x + 3y = 190

2x + 3(180 - 3x) = 190

Distribute the 3

2x + (540 - 9x) = 190

Solve for x

subtract 540 from both sides

2x - 9x = -350

simplify

-7x = -350

divide each side by -7

x = 50

But you still need to solve for y, so substitute the x back into the first equation.(But really you could use either equation)

2(50) + 3y = 190

subtract 100 (2 * 50) from both sides

3y = 90

y = 30

Check your work by resubstituting.

3(50) + 30 = 180.

(b) This one is weird.

(x + 2)^3 expands to (x + 2)(x + 2)(x + 2).

(Remember, it is NOT (x^3 + 8), you don't "distribute" the exponent)

It then simplifies to x^3 + 6x^2 + 12x + 8, and x = 5 is NOT an answer here. Maybe there is something more that you might not have screenshotted?

*edit its not asking to prove x is a solution(which i thought lolllll) its asking to plug x = 5 into the equation*
