Which ordered pair represents the y-intercept of the graph of the equation y = –4x – 7?
Dovator [93]
If <span>y = –4x – 7, the x-intercept is found by setting y=0 and solving for x:

</span><span>0 = –4x – 7  =>  4x = -7, or   x = -7/4       The x-intercept is (-7/4, 0).

</span><span>The y-intercept is found by setting x = 0 and reading off the value of y:

y = –4x – 7  =>  y = 0 - 7, or y = -7.  The y-intercept is (0, -7).</span>

Amir stands on a balcony and throws a ball to his dog, who is at ground level.
Bumek [7]

Answer:

16 meters

Step-by-step explanation:

The height function is given by:

h(x)=-(x+1)(x-7)\\h(x)=-(x^2+x-7x-7)\\h(x)=-x^2+6x+7

The value of x, in seconds, for which the derivate of the height function is zero, is the time at which the maximum height occurs:

\frac{dh(x)}{dx}= h'(x)=-2x+6=0\\x=3

For x = 3 seconds, the height is:

h(3)=-(3^2)+6*3+7\\h(3)=16\ m

The maximum height that the ball will reach is 16 meters.
