Answer: x = -4.6 or -14/3
Step-by-step explanation: you have to isolate the variable by dividing the sides that dont have a variable
Answer:
x=-14/3
Step-by-step explanation:
5-(3x+12)=17
-3x+3=17

Luther evaluated 2³ as 9 and Wade evaluated 3² as 9. Are both students correct? Explain why or why not.
Answer:
No, Wade is correct Luther is incorrect
Step-by-step explanation:
3^2 =3*3 which is 9
2^3 = 2*2*2 which is 8
The two powers are not equal. Wade is correct, but Luther misinterpreted 2 to the power of 3 as 2 factors of 3. He switched the base and exponent. Luther’s value should be 2 times 2 times 2, which is 8.

To rent a carpet cleaner, Tools To Go charges $15.00 for the first hour or part of an hour plus $3.50 for each additional half hour or part of a half hour.
a. Tim picked up a carpet cleaner at 8:10 a.m. and returned it at 4:10 p.m. Determine his rental charge.
b. Calculate the average cost per hour for Tim’s rental.
c. Charmaine rented a carpet cleaner from Carpet Emporium. Her bill was $59.40 for 5.5 h. Compare the average cost per hour for Charmaine’s rental with the average cost per hour for Tim’s rental. How many times as much was Charmaine’s rental?
Step-by-step explanation:
You want to start by creating an equation to find out how much it could cost to rent a carpet cleaner
y= total cost
x=each additional half an hour
y = 3.5(x) + 15
a. Tim rented the carpet cleaner for 4 hours
The first hour is 15
So he had the carpet cleaner for 3 extra hours of 6 addition half an hours
y = 3.5x +15
y = 3.5(6) + 15
y = 21 +15
y= 36
$36
b.
average is mean
add up all the costs and divide by the number of hours
To figure out how much each additional hour is, multiply 3.5 by 2, which means that each additional hour is $7
Add up 15, 7, 7,and 7
15+7+7+7= 15+21= 36
Now divide by 4 to find the average
36/4 = 9
$9 is the average
c.
Start by dividing 59.4 by 5.5
59.4/5.5 = 10.8
$10.8 was the average cost per hour for Charmaine's rental
Now do 10.8/9 to find out how many times as much Charmalaines rental was
10.8/9 = 1.2
Charmaine's rental is 1.2 times Tim's rental

Answer:
B
Step-by-step explanation:
The initial value for a function is the value of y when x=0. For function A, we can see from the table that when x = 0, we have y = 4. For function B, we plug in 0 in our equation and solve: y = 3(0) + 5, or y = 5. So, because function B has a larger value of y when x = 0, function B has the greater initial value because the initial value for Function A is 4 and the initial value for function B is 5.

Write an equation in slope intercept form for a line with a slope of - 3/2 that passes through the point 4,10 help please
Answer:
[tex]y = \frac{ - 3}{2} x + 16[/tex]
Step-by-step explanation:
They give us the slope so this makes it a lot easier.
Slope intercept formula is
y=mx+b
(m) is slope
(b) is y intercept
we can apply our slope into the formula
y=-3/2x+b
Now we can replace (y) with the (y) from the ordered pair they gave us (4, 10), and replace the (x) with the (x) from the ordered pair they gave us
(4, 10)
10=-3/2(4)+b
Now solve
10=-6+b
Add 6 to each side
16=b
Now we we put both our slope and intercept into the formula.
[tex]y = \frac{ - 3}{2} x + 16[/tex]
