Answer:
$10.5 and $7.75
Step-by-step explanation:
Let Landon's hourly rate at babysitting job be 
and at water park be 
now, for the first week Landon babysat for 3 hours and worked at the water park for 10 hours and made 109$.
⇒ 
....(1)
Next week Landon babysat for 8 hours and worked at the water park for 12 hours and made 177$.
⇒ 
....(2)
From equation (2) we get
....(3)
Substituting value of from equation (3) to equation (1) we get
Using value of x in equation (1) we get
Hence hourly rate for Landon for babysitting job is $10.5 and for water park job is $7.75
Answer: D
Step-by-step explanation:
Answer:
C III
Step-by-step explanation:
The rate of change of a linear function is the slope.
f(x) = mx + b is the equation of a linear function whose graph is a straight line. m is the slope.
I f(x) = 4x - 3; m = slope = 4
II f(x) = 1/2 x + 5; m = slope = 1/2
III We can use two points to find the slope.
Let's use points (1, 6) and (2, 12).
m = slope = (y2 - y1)/(x2 x1) = (12 - 6)/(2 - 1) = 6/1 = 6
The three slopes are 4, 1/2, 6.
The greatest rate of change is 6, so the answer is C III.
