Answer:
When 2 people work together the total time equals
Total Time = Time 1 * Time 2 / (Time 1 + Time 2)
Let's solve for Time 1 (which will be Tim's time.)
7 hours = Time 1 * 9 / (Time 1 + 9)
7 * Time 1 + 63 = Time 1 * 9
63 = 2 * Time 1
Time 1 = 30.5 Hours (Tim's Time)
Double Check
Total = 30.5 * 9 / (30.5 + 9)
Total = 274.5 / 39.5
Total = 7 Hours
Again, Tim's Time is 30.5 Hours

Answer:
Option C) $10.40
Step-by-step explanation:
Initial hourly wage = 8 $
raise = 30%
therefore, final hourly wage = (30/100*8) + 8
= 2.4 + 8 = 10.4$

Step-by-step explanation:
Answer:
I think it is question 2, B
The equation is y = mx + b
(18, -19)
substitute these numbers in the equation
-19 = 0(18) + b
-19 is y because it is the y slot in the cordinate and I put 0 for m because m is the slope and x is 18
-19 = 0 + b
b= -19
the equation is
y = 0(x) - 19
y = -19
