Answer:
-15, -17
Step-by-step explanation:
x^2 + 32x = –255 move the -255 to the left
x^2 + 32x +255=0
What two number when multiplied equal 255? Those same two numbers when added make 32. 17*15 make 255 and added is 32
(x+15)(x+17) For x+15=0 move the 15 to the other side. x= -15. Same with x+17=0 is x= -17
x= -15, -17
I think it might be B, not 100%
Answer:
Step-by-step explanation:
use these two equations
A: y = 15
B: y = 2r + 5
a) set the equations equal to eachother for your first answer
15 = 2r + 5
B) solve for r
15 = 2r + 5
10 = 2r
5 = r
after 5 rides the cost will be the same
