Please do NOT tell me the Answer Just tell me How to solve! Thank you.

1. Evaluate the function y = -2x + 5 for x values of -1,0, 1,2, and 3.

2. You deposit $2,500 in an account that pays 5.7% interest compounded anually. What is the balance after five years?

Solve each formula for x.
4. z = 3x + y

5. k = -4xyz

6. 1/9x - 4 = z/3

Answer 1

1. substitute values of x given in the equation and calculate y
2. Calculate how much is 5,7% of 2500. Add it to 2500. Calculate 5,7% of the result and add it. Do this 5 times
3. add costs and benefits and devide by amount of people
4. transform each equation so that on the left side of the equality you have only x and at the right side all the rest

Answer 2

@myko is right!

5 and 6 to be done in the same way as 4

Answer 6

k

Answer 7

Can you do it?

Answer 8

I'm stuck on #4-6

Answer 9

4. z = 3x + y

subtract y from both sides

z-y=3x+y-y
z-y=3x
divide by 3

(z-y)/3=x

x=(z-y)/3
