Answer:
You left out a critical piece of information in the question.
"reaches a height of of the maximum height"
Step-by-step explanation:
Switch y=2x+7 to 2x-y=-7 then multiply that equation by 2 to cancel out the y's. that ends up as 4x-2y=-14 which then you get x=-24. then you substitute x into one of the original equations y= 2(-24)+7 which equals y=-41

Step-by-step explanation:
I think maybe 3) would make the most sense because she wants a random sample of students and the other options are specific on the type of students.
12) (shaded region) 12x25 =300
( un- shaded region) 6x10=60
300-60=240
240 is the answer for #12
