Answer:
Step-by-step explanation:
10) Plugin x = -10 in the equation
h(x) = 0.2x - 4.5
h(-10) = 0.2*(-10) - 4.5
= - 2 - 4.5
= -6.5
11) Plugin a = 8 in the equation
g(a) = (-3/4)a + 2
[tex]g(8) = \dfrac{-3}{4}*8 + 2 \\\\= -3*2 + 2\\\\= -6 + 2\\\\= -4[/tex]
12) h(x) = 3x +3
h(x) = 0
3x +3 = 0
Subtract (-3) from both sides
3x = - 3
Divide both sides by 3
x = -3/3
x = -1
13) g(x) = - x - 5
g(x) = 4
-x - 5 = 4
Add 5 to both sides
-x = 4 + 5
-x = 9
Multiply both sides by (-1)
x = -9
