f(x) = g(x) I don't think has any meaning for this question. I will just solve the equation.
Solution
7x - 12 = - 3x + 10 Add 3x to both sides
7x + 3x -12 = - 3x + 3x +10 Combine
10x - 12 = 10 Add 12 to both sides
10x -12 + 12 = 10 + 12 Combine
10x = 22 Divide by 10
10x/10 = 22/10
x = 2.2
Since it's a right triangle, we can use SOH-CAH-TOA. So tan(x) = opposite/adjacent = 5/20
tan(x) = 1/4 = 0.25
x = arc-tan (0.25) = 14.04°
$29.25 in 3 hours. explanation: if he makes $9.75 in 1 hour then 9.75 x 3 (hours) would equal $29.25
