PLEASE HELP 43 points describe what you think will happen to each of the parabolas below. State what you think the vertex will be.

1. f(x)=(x+2) (2) -3

2. f(x) = -x(2) +7

3. f(x) = (x-4)(2) +1

4. f(x)=(x-4)(2) +1

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

i hope this is what you were looking for.

see attached graph

the answer is ! ?
