Answer:
x =
Step-by-step explanation:
Given
6(8x - 1) = 9(x + 2) ← distribute parenthesis on both sides
48x - 6 = 9x + 18 ( subtract 9x from both sides )
39x - 6 = 18 ( add 6 to both sides )
39x = 24 ( divide both sides by 39 )
x = =
The number of classes Anna can take so the total cost for the month will be the same is 5.
The monthly cost would be $37.50.
When the monthly cost is equal, both equations would be equal: 7.5x = 5.5x + 10
In order to determine the value of x, take the following steps:
Monthly cost when the cost is the same: 7.5 x 5 = $37.50

FV= $160.68
Giving the following information:
Initial investment= $150
Interest rate= 3.5% compounded annually
Number of periods= 2
T<u>o calculate the future value, we need to use the following formula:</u>
FV= PV*(1+i)^n
PV= present value
i= interest rate
n= number of periods
FV= 150*(1.035^2)
B) {(−2, −3), (−3, −2), (2, 3), (3, 2)}
each input of x (-2), (-3), (2), (3) does not have duplicated output value
