Which of these statements are correct about two parallel lines in a coordinate plane? Select three that apply. If they are each translated 7 units to the left, they will remain parallel.
If they are each reflected across the line y = x, they will remain parallel.
If they are each rotated 180° about the origin, they will not remain parallel.
If they are each reflected across the x–axis, they will not remain parallel.
If they are each rotated 270° about the origin, they will remain parallel.
If they are each translated 9 units down, they will not remain parallel.

If they are each rotated 180° about the origin, they will not remain parallel.

If they are each translated 7 units to the left, they will remain parallel.

If they are each rotated 270° about the origin, they will remain parallel.

Step-by-step explanation:

I got them

answer: it is a.,b.,d.

step-by-step explanation:

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
