Even numbers end with 2,4,6,8, or 0. Thus, 28 is the even number.
According to your description, you can simply plug in all the numbers:
d(47) = 2.15 * 45^2 / (58.4*0.34) = 219.27 m
The total cost for plumber number 1 expressed as a function of x is
c1(x)=45x+90
That is, the charge per hour times the number of hours plus the fixed charge for a visit.
Using the same pattern, write the function for the second plumber. Then set the two functions equal to each other and solve for
Answer:
y = 8x + 2
Step-by-step explanation:
Slope-intercept form: y = mx + b
m = slope
b = y-intercept value
