Answer:
y = 1
Step-by-step explanation:
G(-2) means "evaluate the equation at -2"; it's asking you to swap out the "x" in the equation and sub in -2.
g(x) = x² + 3x - 2 ... plug in -2
g(-2) = (-2)² + 3(-2) - 2 ... simplify
g(-2) = 4 + (-6) - 2 ... add/subtract
g(-2) = -4
(x + 6)/2 - (x - 8)/3 = 5
Multiply each term by 6:-
3(x + 6) - 2(x - 8) = 30
3x + 18 - 2x + 16 = 30
3x - 2x = 30 -18 - 16
x = 30 - 34
x = -4 (answer)
Answer:
8
Step-by-step explanation:
Take the total, 50.35, and subtract 19.95:
50.35 - 19.95 = 30.40
Now divide 30.40 by 3.80:
(30.4)/(3.8) = 8
Therefore, Tony bought 8 markers.
