Given :
Sierra is getting her car fixed at a mechanics. The total cost after tax is represented by 0.065(30h) + 30h, where h represents the number of hours it takes to repair the car.
To Find :
What part of the expression represents the amount of money she will have to pay in tax.
Solution :
Total cost , T = 30h( 1 + 0.065)
T = 30h + 30h(0.065)
T = (30h) + (30h )× 6.5 %
Here, 30h is the cost of repairing the car.
Other part shows the tax she have to pay which is 6.5% of the total amount.
Hence, this is the required solution.
Answer:
7+3(-4)2 have negative value
Step-by-step explanation:
Answer:
(f+g)(x) = 0 if <em>x = -2 </em>
Step-by-step explanation:
(f+g)(x) = f(x) + g(x) = x² - 2x + 6x + 4
(f+g)(x) = x² + 4x + 4
x² + 4x + 4 = 0
(x + 2)² = 0
So, <u>x = -2</u>.
