Ok here’s the answer! I again had to crop out the first step. here it was to divide equation 1 by 3 and add that to equation 2. all you need do you show that step is to write equation 1: -3x+2y=8 and equation 2: (11y/3)=35/3
Answer:
The answer should be A'(-9,3) B'(12,-6)
Step-by-step explanation:
If you dialate, you multiply every coordinate by 3. -3 x 3= -9. 1 x 3=3. 4 x 3= 12. -2 x 3= -6. So, the last option is correct.
420 would be the middle number.

Answer: x = 17/9
Step-by-step explanation: Lets solve for x.
9x - 5 = 12
9x - 5 + 5 = 12 + 5
9x = 17
9x/9 = 17/9
x = 17/9
Answer: Simplified Equation (10x-10)
Answer if 3=x is 20
Step-by-step explanation:
the original side lengths are 3x and (2x-5) so multiply both those by 2.
Now you have 6x and 4x-10.
Now combine those and you have 10x-10.
Then plug in 3 for x
