F(x) = -x2 - 10x find f(-7)

119

Step-by-step explanation:

f(x)= -x²-10x

f(-7)= -7²-10(-7)

7²= -7*-7   -10*-7

f(-7)=49+70

f(-7)=119

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to

it could be 1,3 and more others to create a cylinder.
