Answer:
1, 2 and 3
Step-by-step explanation:
Let
t -----> the number of hours the job takes
C(t) -----> the total cost for the service
we have
This is the equation of a line in slope intercept form
where
The slope m is equal to 
The y-intercept is the point (0,95) ---> The cost is $95 for the value of t equal zero (fee)
therefore
<u><em>The statements that are true</em></u>
1 a house call fee costs $95
2 the plumber charges $125 per hour
3 the number of hours the job takes is represented by t
Answer:
x=2, y=6

Answer:
There are no solutions to the inequality.
Step-by-step explanation:
|x - 3| < x – 3
1. Separate the inequality into two separate ones.
(1) x – 3 < x – 3
(2) x – 3 < -(x – 3)
2. Solve each equation separately
(a) Equation (1)
(b) Equation (2)
For example, if x = 0, we get
|0 - 3| < 0 - 3 or
3 < -3
Answer:
2x³ + 5x² - 12x
Step-by-step explanation:
The correct answer doesn't seem to be listed...
(fg)(x) = (2x² - 3x)(x + 4)
Which equals...
2x²(x) + 2x²(4) + (-3x)(x) + (-3x)(4)
Which simplifies to...
2x³ + 8x² - 3x² - 12x
2x³ + 5x² - 12x
