Answer: The least number of minutes that he has used his phone in a month is 1248
Step-by-step explanation:
Let m represent the number of minutes that he used his phone in a month.
For his phone service, Michael pays a monthly fee of $16, and he pays an additional $0.04 per minute if use. This means that if he used m minutes in a month, the total cost would be
16 + 0.04m
The least he has been charged in a month is $69.52. This means that
16 + 0.04m ≥ 65.92
0.04m ≥ 65.92 - 16
0.04m ≥ 49.92
m ≥ 49.92/0.04
m ≥ 1248 minutes
The correct answer is option D.Which is ( x - 1 ).
<h3>What is a quadratic equation?</h3>
It is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.
The solution of the given quadratic equation will be:-
-2x² - 22x + 24 = 0
x ² + 11x - 12 = 0
x² + 12x - x + 12 = 0
x ( x + 12 ) -1 ( x + 12 ) = 0
( x -1 ) ( x + 12 ) = 0
Therefore the correct answer is option D.Which is ( x - 1 ).

Answer:
Total = m + j
= 3 + m + 21
Step-by-step explanation:
Mails = 3 miles
Jared = 3 miles + 21 miles
j = m + 21
m = 3
Total = m + j
= 3 + m + 21
Where,
m = 3
Total = 3 + m + 21
= 3 + 3 + 21
= 27
