If you distribute the 2 on the left you end up with

6y-8=10

then add 8 to both sides

6y=18

then divide by 6 on both sides

y=3

and if you plug it back in it should equal 10

2((3)(3)-4)=10

10=10<span />

2(3y-4)=10\ \ \ |divide\ both\ sides\ by\ 2\\\\\frac{2(3y-4)}{2}=\frac{10}{2}\\\\3y-4=5\ \ \ \ \ |add\ 4\ to\ both\ sides\\\\3y=9\ \ \ \ \ |divide\ both\ sides\ by\ 3\\\\\boxed{y=3}

Suppose that Marlie had decided to apply for a private loan rather than a federal loan. She has
34kurt

Using simple interest, and considering a loan of $5,000, it is found that:

a) Her monthly payment is of $74.17.

b) She will pay back $8,900.

c) The total interest amount is of $3,900.

The amount of money after <u>t years</u> in <em>simple interest</em> is modeled by:

A(t) = A(0)(1 + rt)

In which:

  • A(0) is the initial amount.
  • r is the interest rate, as a decimal.

In this problem:

  • The loan is of $5,000, hence A(0) = 5000.
  • The APR is of 7.8%, hence r = 0.078
  • 10 years, hence n = 10

Item b:

A(10) = 5000[1 + 0.078(10)] = 8900

She will pay back $8,900.

Item a:

$8,900 will be paid in 10 x 12 = 120 months, hence:

M = \frac{8900}{120} = 74.17

Her monthly payment is of $74.17.

Item c:

<u>Loan of $5,000, pays back $8,900</u>, hence:

8900 - 5000 = 3,900

The total interest amount is of $3,900.

Determine the solution and indicate the restrictions on the variable.
cupoosta [38]

Answer:

B

Step-by-step explanation:

Subtract 20 from both sides:

-\sqrt{9-8x} =-15

Divide both sides by -1:

\sqrt{9-8x} =15

Square both sides:

9-8x=255

Subtract 9 by both sides:

-8x=216

Divide both sides by -8:

x=-27

That means that either a or b is correct and since 9/8 is positive that means it needs to bee less than 9/8 so the correct answer is B
