Answer:
y = (25/4)(x + 5)^2
Step-by-step explanation:
1. Interchange x and y, obtaining: x = -5 + (2/5)√y
2. Solve this result for y: x + 5 = (2/5)√y
Squaring both sides, we get (x + 5)^2 = (4/25)y
Multiplying both sides by (25/5) cancels out the (4/25) coefficient:
y = (25/4)(x + 5)^2 This is the inverse of the given function.
Answer:
-25
Step-by-step explanation:
Evaluate -x - 6 x + 10 where x = 5:
-x - 6 x + 10 = -5 - 6×5 + 10
-6×5 = -30:
-5 + -30 + 10
-5 - 30 + 10 = 10 - (5 + 30):
10 - (5 + 30)
5 + 30 = 35:
10 - 35
10 - 35 = -(35 - 10):
-(35 - 10)

Answer: -25
450 multiplied by .025 also known as 2.5 percent which equals 11.25 dollars
which is her commission for the week
From the information given, she owes her parents a total of $1854.
She will take a period of 18 months to repay the whole loan.
We first find out the how much is each installment per month.
We divide the whole amount by 18 months so 1854/18 = $103
If she pays 103 dollars per month, then at one year (12 months) she would have paid: 103 × 12 = 1,236 dollars.
She would owe 1854 - 1236 = 618
There she would still be owing her parents $ 618 after one year.
