Answer:
The scale factor is 3/2.
Step-by-step explanation:
Let's use the side PQ.
The original length was 8 units.
And the new length is 12 units.
Let the scale factor be k. Therefore:
![8k=12](https://tex.z-dn.net/?f=8k%3D12)
By dividing both sides by 8, we can see that our scale factor from ΔPQR to ΔP'Q'R' is:
![\displaystyle k=\frac{12}{8}=\frac{3}{2}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20k%3D%5Cfrac%7B12%7D%7B8%7D%3D%5Cfrac%7B3%7D%7B2%7D)
Answer:
y = 1/2x
Step-by-step explanation:
Choose two points- I chose (10,5) and (0,0)
Find the slope using y2-y1/x2-x1
Use y - y1 = slope (x -x1) to get your equation
The answer should be y =1/2x

Answer:
(-8, 0), (0,0) and (7, 0)
Step-by-step explanation:
When f(x) = 0 the curve of f(x) intercept x-axis, that is, y = 0. This points are called roots or zeros of the polynomial.
From the picture, we can see that f(x) = 0 at points (-8, 0), (0,0) and (7, 0)
