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
Answer: The answer is x = -10

Answer:
(-3, 8)
Step-by-step explanation:
For m the midpoint of xy, we have ...
m = (x+y)/2 ⇒ y = 2m-x
y = 2(4, 3) -(11, -2) = (2·4 -11, 2·3 +2)
y = (-3, 8)

Answer:

Step-by-step explanation:
let w represent the width then length = w + 7
The perimeter of the rectangle = 2w + 2(w + 7) = 2w + 2w + 14 = 4w + 14
The perimeter is given as 54 m, thus
4w + 14 = 54 ( subtract 14 from both sides )
4w = 40 ( divide both sides by 4 )
w = 10
Thus
width of playground = w = 10 m
length of playground = w + 7 = 10 + 7 = 17 m
