Answer:
Step-by-step explanation:
carnival A : $ 6 dollar admission and $ 1.50 per ride
A(x) = 1.5x + 6
carnival B : $ 2.50 admission and $ 2 per ride
B(x) = 2x + 2.5
how many rides can Marnie go on so that the total cost of attending both is the same...
1.5x + 6 = 2x + 2.5
6 - 2.5 = 2x - 1.5x
3.5 = 0.5x
3.5 / 0.5 = x
7 = x <=== she would have to go on 7 rides for them to both cost the same
Answer:
(-5, -2)
Step-by-step explanation:
Note that on the interval (-5, -2), the line segment representing the graph is pointed downward: y decreases as x increases.
(y-15)(y+15) if you do (y+15)^2, then that'll be y^2 + 225
Answer:
7.a) 5
7.b) 1/2
8. 1
Step-by-step explanation:
7.
a)
Read the points on the graph (0, 0) and (1, 5).
slope = (5 - 0)/(1 - 0) = 5/1 = 5
b)
read the points on the graph (0, 0) and (4, 2).
slope = (2 - 0)/(4 - 0) = 2/4 = 1/2
8.
Points (1, 4) and (5, 8)
slope = (8 - 4)/(5 - 1) = 4/4 = 1
19/20
19/20 = 0.95
0.9 < 0.95
