I believe that it's A neither, because I don't think that it could be displayed on a coordinate graph when it has an exponent in it. So I think it's A. Let me know if I'm correct. ;-)
Answer:
1) B) 10
2) B) 9
Step-by-step explanation:
1) 10x+15=115
10x=100
x=10
2) 12x+17=125
12x=108
x=9
Answer:
If you are looking for an equation, then it would be 25 < x.
Step-by-step explanation:
When ur polynomial has more then one variable....and this one does...the degree is the highest term degree
7a^3b^2 ....this term has a degree of 5
2a^4...this term has a degree of 4
4b....this term has a degree of 1
15....this term has a degree of 0
so the highest degree term has a degree of 5....so that is the degree of this polynomial.
now if u just had 1 variable, the degree would be the highest exponent
Part A: The discounted monthly fee is $22.49 (original cost of $29.99 multiplied by 75%, the amount the customer would pay since 25% is discounted.) Since you would also pay $44.99 for setup, your equation is $44.99+$22.49m
Part B: Add 1.08 (108%; the customer pays 100% of the cost plus 8% more for tax) to your equation for the sales tax. 1.08(44.99+22.49m)
Part C: Plug in 4 for m (m represents months).
1.08(44.99+22.49•4)
1.08(44.99+89.96)
1.08(134.95)
$145.75
