Directions and Analysis Task 1: Throwing a Ball
Cecily is on her roof and wants to throw a ball straight up in the air and figure out how
long it will take to reach the ground. The function that models an object falling to the
þround is f(x) = -32x2 + VX + d. In this function, x is time, vis the initial (vertical) velocity
in feet per second, and d is the initial distance above the ground in feet. If v is positive,
then the initial velocity is upward. If v is negative, the initial velocity is downward.
a. Write the function if Cecily releases the ball 40 feet above the ground at a
velocity of 64 feet per second, and then graph it using the Edmentum Graphing Tool.
Capture a screenshot of your graph and paste it below.

the answer is c hope it

step-by-step explanation:

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

collect results in alphabetical order:

answer:   {x = -1/2 ,   y = -1
