Answer: Here is the answer hope that helps ( Thanks for the points) (Btw my teacher helped me with it)

Step-by-step explanation:

Simplifying

b(x) = 18 + -0.5x

Multiply b * x

bx = 18 + -0.5x

Solving

bx = 18 + -0.5x

Solving for variable 'b'.

Move all terms containing b to the left, all other terms to the right.

Divide each side by 'x'.

b = 18x-1 + -0.5

Simplifying

b = 18x-1 + -0.5

Reorder the terms:

b = -0.5 + 18x-1

Answer:

19, 18, 15.5

Step-by-step explanation:

given :

b(x)=18-0.5x

when x = -2,

b (-2) = 18 - 0.5 (-2) = 18 +1 = 19  (answer)

When x = 0,

b(0) = 18 - 0.5 (0) = 18 - 0 = 18   (answer)

when x = 5,

b(5) = 18 - 0.5(5) = 18 - 2.5 = 15.5  (answer)
