Y = -2x - 3
Y = -2 + 5

-2x - 3 = 2x + 5

x= -2

y= -2 x (-2) -3

y= 1

( x, y) = (-2, 1)

The answer is (-2, 1)

Answer:

at first , you need the sum of both equations . It will be like :

2y= 0 + 2

Y=1

_____

now that you know the value of Y , place it in the one of the equation that you like , forexample i place it in the second equation and find out that the value of x is ( -3/2)

1= 2X+5

-4=2X

X= -2

Hope it helps , good luck ^.^

Answer:

Time t = 2 seconds

It will reach the maximum height after 2 seconds

Completed question;

Amir stands on a balcony and throws a ball to his dog who is at ground level. The ball's height, in meters above the ground, after t seconds that Amir has thrown the ball is given by:

H (t) = -(t-2)^2+9

many seconds after being thrown will the ball reach its maximum height?

Step-by-step explanation:

The equation of the height!

h(t) = -(t-2)^2 + 9 = -(t^2 -4t +4) + 9

h(t) = -t^2 +4t -4+9

h(t) = -t^2 + 4t +5

The maximum height is at dh/dt = 0

dh/dt = -2t +4 = 0

2t = 4

t = 4/2 = 2

Time t = 2 seconds
