What's the least common denominator of these? 1/3x 2/x 3/7

5

step-by-step explanation:

a reflection across the x axis and a 90 degree rotation left and right.

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)
