Which property justifies step 3 when solving the equation below? 3(x + 3) = 6(x-4)
Step 1: 3(x + 3) = 6(x-4)
Step 2: 3x + 9 = 6x-24
Step 3: 3x + 9-9 = 6x-24-9
Step 4: 3x - 6x = 6x - 6x - 33
Step 5: -3x = -33
Substitution property of equality
O Subtraction property of equality
Distributive property
Additive inverse property

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.

the answer is 9 because the question is telling how much it be together.
