The answer is 9x+8. if you distripute the 2, you get 2x-6. if you distribute the 7, you get 7x+14. then you combine like terms ans get 9x+8

2(x-3)+7(x+2) now you time 2*x which you will get 2x, then you will times 2*-3 which is -6, now you times 7by x and you get 7x and times 7by 2 and you get 14 it should look like this

2x-6+7x+14 and then you add 2x+7x which is 9x then 14+-6 that is 8 it should look like this

9x+8

Answer:

B: 112.5

Step-by-step explanation:

first, we split up the rhombus into two triangles, with the height of 15 and the length of 7.5. when you multiply these you will get 112.5, and normally if you are just getting the area of the triangle, then you would divide it by two, but seeing that we have 2 triangles here, we would multiply it by two afterwards so an easier way to do it is just to not divide.

For f (x)= -x + 8, what is the value of x for which f(x) = 9?

Elina [12.6K]

Answer:

x=-1

Step-by-step explanation:

f (x)= -x + 8

Let f(x) = 9

9 = -x+8

Subtract 8 from each side

9-8 = -x+8-8
