Answer:

  C. A horizontal stretch by a factor of 5/4

Step-by-step explanation:

Replacing x in f(x) by kx introduces a horizontal compression by a factor of k, or a stretch by a factor of 1/k. Here, we have k=4/5, so the curve is stretched horizontally by a factor of 5/4.

Which test point holds true for the inequality 3/2y-2x>=1? Where does the shaded area lie for this inequality? The test point
Tanya [424]

The test That holds true for this inequality is given as 1/4 and 1

<h3>How to solve for the inequality</h3>

3/2 y - 2x > 1

The goal is to make y the subject

then

3/2 y > 2x + 1

We have to divide through the equation by 3/2

Such that  y  > 4/3 x + 2/3

what is the answer to this question. please respond. I need the answer very quick.my teacher is going to get mad at me
amm1812

It is a ratio problem...

2 dogs need 144 feet = 2 : 144

Simplify the ratio = 1 : 72

Multiply both sides by 8 (8 dogs) = 1*8 :144*8

Simplify the ratio = 8 : 1152

8 dogs need 1152 feet of fencing

Hope this helps!

A population of 120,000 grows 3% per year for 15 years, how much will the population be after 15 years?
Wewaii [24]
270,000 is the answer because you have three over 100 so you do 100 divided by three which give you 0.15 then you do 120,000 times 0.15 to find out how much it grows per year to get 18,000 then you multiply 18’000 by 15 and get 270’000

Use Pythagorean Theorem to solve for x.<br><br> HELP ME PLZZZZ!!!! ASAP
4vir4ik [10]

Answer: 2\sqrt{22}

Step-by-step explanation:

Pythagorean theorem: a^{2} +b^{2} = c^{2}, where a and b are the legs and c is the hypotenuse.

We can solve for x by only using the left side of the triangle. Since we're only using the left side of the triangle, we can reduce 18 by 2 to get 9. Now we plug in our information to the equation.

9^{2} +b^{2} = 13^{2}

81 +b^{2} = 169

Since we don't know what b^{2} is, we're going to isolate it by subtracting 81 on both sides

b^{2} = 88

We have to square root both sides in order to find out b (or x in the problem).

\sqrt{b^{2}} = \sqrt{88}

When you put this on a calculator it would result in 2\sqrt{22} which is the answer d in the problem.
