The given expression is:
![4 x^{2} -5](https://tex.z-dn.net/?f=4%20x%5E%7B2%7D%20-5)
So, there are two terms in the expression
1)
![4 x^{2}](https://tex.z-dn.net/?f=4%20x%5E%7B2%7D%20)
2) -5
The constant term is -5.
The co-efficient of
![4 x^{2}](https://tex.z-dn.net/?f=4%20x%5E%7B2%7D%20)
is 4.
Answer:
![\bold{[g\circ f](x) = 2x^2-13x+2}](https://tex.z-dn.net/?f=%5Cbold%7B%5Bg%5Ccirc%20f%5D%28x%29%20%3D%202x%5E2-13x%2B2%7D)
Step-by-step explanation:
![{}[g\circ f](x) = g[f(x)] \\\\{} [g\circ f](x)= g(x-5)\\\\{} [g\circ f](x) = 2(x-5)^2+7(x-5)-13\\\\{} [g\circ f](x) = 2(x^2-10x+25)+7x-35-13\\\\{} [g\circ f](x) = 2x^2-20x+50+7x-48\\\\{} [g\circ f](x) = 2x^2-13x+2](https://tex.z-dn.net/?f=%7B%7D%5Bg%5Ccirc%20f%5D%28x%29%20%3D%20g%5Bf%28x%29%5D%20%5C%5C%5C%5C%7B%7D%20%5Bg%5Ccirc%20f%5D%28x%29%3D%20g%28x-5%29%5C%5C%5C%5C%7B%7D%20%5Bg%5Ccirc%20f%5D%28x%29%20%3D%202%28x-5%29%5E2%2B7%28x-5%29-13%5C%5C%5C%5C%7B%7D%20%5Bg%5Ccirc%20f%5D%28x%29%20%3D%202%28x%5E2-10x%2B25%29%2B7x-35-13%5C%5C%5C%5C%7B%7D%20%5Bg%5Ccirc%20f%5D%28x%29%20%3D%202x%5E2-20x%2B50%2B7x-48%5C%5C%5C%5C%7B%7D%20%5Bg%5Ccirc%20f%5D%28x%29%20%3D%202x%5E2-13x%2B2)
This statement is actually false.

Answer:
3a. yes
3b. y= 75x
3c. 600 mi
3d. 10 inches
Step-by-step explanation:
3a: if you divide the y by the x, you'd get 75 everytime, meaning it's proportional.
3b: y would equal the amount of inches multiplied by 75, so y=75x
3c: you can use the equation and substitute the x for 8, so y=75(8), giving you 600 miles
3d: you can also use the equation in reverse, if the actual miles is 750, then this is your y, so it would look like 750=75x and to solve you'd divide, 750/75, giving you 10 inches
