Answer:
First part: -10x-4y=-12
Second half: infinitely many solutions
Step-by-step explanation:
Just did the assignment and got it correct
The student made the mistake in Step 2.
It should be m∠o + m∠p = 180 (Supplementary angles)
If this is corrected, then, since m∠m + m∠n + m∠o = 180 from Step 1,
we have,
m∠m + m∠n + m∠o = m∠o + m∠p which is Step 3.
Cancelling m∠o both sides, we get,
m∠m + m∠n = m∠p which is Step 4.
The answer is B., valid because people were chosen randomly
This would make it a valid survey
Hope this helps!

Math is really important in life. it can help you with your jobs. it also helps you at school. it also helps you with figuring out the perimeter of your house.
The dilation factor Sophia is using appears to be
(image coordinate)/(original coordinate) = -9/-3 = 15/5 = 3
Then the problem tells us
(pre-image point)×3 = (3, 1)
so we conclude
(pre-image point) = (3, 1)/3 = (1, 1/3)
