Answer:
goku solos!?!?!
Step-by-step explanation:
goku solos
Free movie, F = 87pts
Initial reward, I = 10pts
Additional reward, A = 7pts
Movie visit, X
F = I + XA
87 = 10 + 7X
X = (87-10)/7
X = 11
After 11 movie visits Andrew will have enough points for a free movie.
At least means greater than or equal to.
10 × (15+b) ≥ 26
150+10b ≥ 26
10b ≥ -124
b ≥ -12.4
Answer:
x = - 1
Step-by-step explanation:
Given
3x + 2 = y and y = - 1
Substitute y = - 1 into the equation and solve for x, that is
3x + 2 = - 1 ( subtract 2 from both sides )
3x = - 3 ( divide both sides by 3 )
x = - 1
This is verified by the point on the graph with coordinates (- 1, - 1)
