Answer:
Step-by-step explanation:
To obtain the standard form of the equation of the parabola y=2(x+4)^2-7, first perform the indicated operations:
y = 2[x^2 + 8x + 16 - 7], or
y = 2[x^2 + 8x + 9],
or y = 2x^2 + 16x + 18
None of the given possible answers match. The fourth one, D, is closest to the above result, differing only in the constant term (25 versus 18).
Answer:
0.3 or 3/10
Step-by-step explanation:
100%=1 so 30%=0.3
I hope i am answering what you are asking for but it would be an equilateral triangle because you have two sides and angles that are the same
1/9, sorry if it’s wrong!! Hopefully it helps you!
Answer:
The price of having her car detailed before tax = $55
Step-by-step explanation:
She pays the cashier with a $100 bill and gets $40.60 in change.
She paid = $100 - $40.60
= $59.40
Sales tax = 8%
what was the price of having her car detailed before tax?
Let x= price of having her car detailed before tax
8% of x + x = $59.40
(0.08 * x) + x = $59.40
0.08x + x = 59.40
1.08x = 59.40
Divide both sides by 1.08
x = 59.40 / 1.08
x = $55
Therefore, the price of having her car detailed before tax is $55
Check:
8% of $55
= 0.08*55
= $4.40
Tax + price before tax
$4.40 + $55
= $59.40
