Answer:
m=-3
Step-by-step explanation:
Define variable- 4.5x
Equation - 15+ 4.5x =42
Solution- x=6
15+ 4.5x =42
4.5x = 27
X=6
Hi there!

3(x - 2) < 18
Begin by dividing both sides by 3:
3(x - 2)/3 < 18/3
x - 2 < 6
Add 2 to both sides:
x - 2 + 2 < 6 + 2
x < 8
Answer: 1
f(x) = 3x - 4 => f(3) = 3.3 - 4 = 9 - 4 = 5
g(x) = x² => g(2) = 2² = 4
=> f(3) - g(2) = 5 - 4 = 1
