3x + b = 5x - 7
3y + c =5y-7

in the equations above, b and c are constants. if b is c minus 1/2, which of the
following is true?

a. x is y minus 1/4
b. x is y minus 1/2
c. x is y minus 1
d. x is y plus 1/2

n

step-by-step explanation:

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
