Answer:
Step-by-step explanation:
11) y = -1x - 2
12) y = -(3/2)x + 3
13) y = 3x - 2
14) y = (3/4)x + 1
15) y = (1/2)x + 1
16) y = -(2/5)x
17) y = 7x + 2
18) y = (4/3)x - 4

Answer:
The balance in the account after 20 years will be $11280.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:

In which E are the earnings, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:
.
In this problem
We want to find T, when 
The first step is find the earnings due to interest. So

Adding to the principal to find the balance

The balance in the account after 20 years will be $11280.

Answer:
(- 2, - 1 )
Step-by-step explanation:
Given the 2 equations
2x - 3y = - 1 → (1)
x + 4y = - 6 → (2)
Rearrange (2) expressing x in terms of y by subtracting 4y from both sides
x = - 6 - 4y → (3)
Substitute x = - 6 - 4y into (1)
2(- 6 - 4y) - 3y = - 1 ← distribute and simplify left side
- 12 - 8y - 3y = - 1
- 12 - 11y = - 1 ( add 12 to both sides )
- 11y = 11 ( divide both sides by - 11 )
y = - 1
Substitute y = - 1 into (3) for corresponding value of x
x = - 6 - 4(- 1) = - 6 + 4 = - 2
Solution is (- 2, - 1 )
