Rate of change between 1 and 3: find the y values for 1 and 3:
Rate of change = (6-1) / (3-1) = 5/2
Rate of change from 2 and 4:
= (10-3) / (4-2) = 7/2
The rate from 2 to 4 is larger because 7/2 is larger than 5/2
Answer:
B. Carl yearns more per hour
C. put line through points (1,15) and 3,45) on graph and you will have Carl's earnings per hr.
Step-by-step explanation:
Louis earns 12$ per hr (y=12x)
Carl yearns 15$ per hr (y=15x)
to find what carl yearns hourly you divide 45 by 3 which is 15.
(Explaination of answer for question b)
C isnt hard once you find y=15x.

Answer:
h(-3) = 4.2 or 21/5
h(1) = 0.2 or 1/5
Step-by-step explanation:
Plug in -3 for t.
-(-3) + 6/5 = 4.2 or 21/5
Plug in 1 for t.
-(1) + 6/5 = 0.2 or 1/5
This situation can be represented by
y = 33x + 223
y = 32x + 239
I still like substitution, so let’s plug in 33x + 223 into the second equation
33x + 223 = 32x + 239
Move the terms into appropriate sides
33x - 32x = 239 - 223
Combine like terms
x = 16
Then plug in x for any equation
y = 32(16) + 239
y = 751
