Answer:
C
Step-by-step explanation:
related equation
-16t^2 + 32t + 20 = 0
-4t^2 + 8t + 5 = 0
Δ/4 = 16 + 20 = 36
t1 = (-4 + 6)/-4 = -1/2
t2 = (-4 - 6)/-4 = 5/2
-16(t+1/2)(t-5/2)
-16(2t+1/2)(2t-5/2)
-4(2t+1)(2t-5)
Answer:
f(x) = 1.50x - 15
Step-by-step explanation:
Given that:
Worth of prepaid charge card = $15
Cost per ride = $1.50
Amount after each ride :
In solpe - intercept form:
Cost per ride = slope = 1.50
Intercept = $15
Amount left after each ride, f(x)
Number of ride, x
f(x) = 1.50x - 15
