What's the solution for y+1/2=3/4

creativ13 [48]

$\frac{y+1}{2} = \frac{3}{4}$

2(y+1) = 3 LCD is 4

2*y + 2*1 = 3

2y + 2 = 3

2y = 3 - 2

2y = 1

y = 1 / 2

Which describes an isometric transformation? dilation/ rotation/ side length change/ angle change

Westkost [7]

Answer:

Choose the inequality below that x=0 is a solution to.

krok68 [10]

remember: a filled dot means it includes that point and an empty dot means it doesn't

A. has empty dot at 0 so x=0 is not incuded in the solution

B. has filled dot at x=0 so x=0 is a solution

C. has empty dot at 0 so x=0 is not incuded in the solution

D. the line doesn't even go over x=0 so not a solution

answer is B
