You know that the computer technician has a flat 65 dollar service charge. This will be added to the hours worked.
hours= h
40 dollars per hour. So, every hour worked is worth 40 dollars.
c(h)= 40h+65
If you input the number of hours he worked as h, you would have the total amount of money he made if you solved the expression.
I hope this helps!

Answer:
D
) Close to 50 times but probably not exactly 50 times
Reasoning:
Right in the beginning, we know that she flips the coin 100 times. Which means A and B cannot be true. Between C and D, only D makes sense because you can't be sure if something will land exactly a number of times.
Answer:
x=0
Step-by-step explanation:
X -8 = -8
Add 8 to both sides to get x alone
X = 8 - 8
X = 0
Answer:
2 times larger

Answer:
125x - 33x⁴
Pull out like factors :
125x - 27x⁴ = -x • (27x3 - 125)
Factoring: 27x³- 125
Theory : A difference of two perfect cubes, a³ - b³ can be factored into
(a-b) • (a² +ab +b²)
(a-b)•(a²+ab+b²) =
a³+a²b+ab²-ba²-b²a-b³ =
a³+(a2b-ba²)+(ab²-b²a)-b³ =
a³+0+0+b³ =
a³+b³
Check : 27 is the cube of 3
Check : 125 is the cube of 5
Check : x³ is the cube of x¹
Factorization is :
(3x - 5) • (9x² + 15x + 25)
