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), x
kumpel [21]

Answer:

12m

Step-by-step explanation

If the height of the ball after x seconds be modelled by the equation

h(x)=−(x−2)² +16

The height of the ball at the time it is thrown will be the height at the initial time. At that point that it is initially thrown the time is 0seconds i.e x = 0

To get the height at t x = 0seconds, we will substitute x = 0 into the modeled function to have;

h(0) = -(-0-2)²+16.

h(0) = -(-2)²+16

h(0) = -4+16

h(0) = 12

The height of the ball at the time the ball is thrown is 12m

Make X the subject :))
Rom4ik [11]

Answer:

x = \frac{3 + 8y}{y - 1}

Step-by-step explanation:

y = \frac{x + 3 }{x - 8}

Cross multiply,

y(x - 8) = x +3

yx - 8y = x + 3

yx - 8y -x = 3

yx - x     = 3 + 8y

  (y - 1)x = 3 +8y

           x = \frac{3 + 8y}{y - 1}
