Solve the system of equations using substitution or graphing. y = -x2 + 4x + 5
y = x + 1
A) (-1,0) and (6, 7)
B) (-1,0) and (4,5)
C) (1, 2) and (6, 7)
D) (1, 2) and (4, 5)

answer: it is 8

step-by-step explanation:

you know why its 8

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9

a

step-by-step explanation:

p - 6

step-by-step explanation

so you know that it cost $6 to see a movie you subtract p - 6 to get your answer

hope this !
