7. What is the multiplicative inverse of 1/4?
1/8

A multiplicative inverse is what you multiply a number by to get 1.

So, you will need to multiply a number by 1/4 and 1/8 to get one.

The multiplicative inverse of 1/4 is 4 because 1/4 multiplied by 4 is 1.

The multiplicative inverse of 1/8 is 8 because 1/8 multiplied by 8 is 1.

a) y = -3x +2

b) y = 1/2x -6

these 2 can be combined into one equation.

-3x +2 = .5x -6

8 = 3.5x

x = 8 / 3.5 = 2.2857142857

y = -3 * (8 / 3.5) +2

y = (-24 / 3.5) + 2

y = -4.8571428571
