STEP
1
:
Equation at the end of step 1
(((3 • (x3)) - 13x2) + 18x) - 8 = 0
STEP
2
:
Equation at the end of step
2
:
((3x3 - 13x2) + 18x) - 8 = 0
STEP
3
:
Checking for a perfect cube
3.1 3x3-13x2+18x-8 is not a perfect cube
First, organize all of the like terms. All of the numbers to one side, all of the variables to the other. Then, divide to get x by itself.
Answer:
just one solution
Step-by-step explanation:
4x + 8 = −2 − 2 + 5x
4x - 5x = -2 - 2 - 8
x = 12
M: cost per hour
b: initial charge fee
x: hours (h)
To make both company to charge the same amount:
12x+376=15x+280
376-280=15x-12x
96=3x
X=32
So it took 32 hour to 2 company charge the same amount.
The cost gonna be: 12.(32)+376=760$
