Answer:

B. -13w - 7

Step-by-step explanation:

Combine -6w and -7w together to get -13w as the first part of your answer since you are subtracting from a negative to get a negative answer and combine -8 and 1 together to get -7 since you are adding 1 from -8 to go up.

Solve for y. <br> 2x+6y=12
Veronika [31]
2x + 6y = 12

2x - 2x + 6y = 12 - 2x

6y = 12 - 2x

6y/6 = 12/6 - 2x/6

Y = 2 - 2/6 X

Y = 2 - 1/3 X or

Y = -1/3 X + 2.

First graph it

#1

Maximum height is the y coordinate of vertex

  • (2,144)

Max height

  • 144m

#2

Time is the x coordinate of vertex

  • 2s

#3

  • y is 0

\\ \rm\Rrightarrow -16t^2+64t+80=0

x intercepts are the solutions

  • (-1,0)U(5,0)

Take it positive

  • t=5s

#4

put in function

  • y=-16(1)+64+80=-16+144=128ft
