Four more than a number is more than 13

X > 9 is the answer. This is the correct answer because you would subtract 4 from each side of the equation, which would leave X on one side and nine on the other. The inequality remains the same since you are not dividing at all by any negative numbers

Sharon kicks a ball from the ground into the air with an upward velocity of 64 feet per second. The function h = -16t2 + 64t mod

iren2701 [21]

When the ball reaches the ground is equal to one of the zeros, or x-intercepts. In order to find the zeros of a function, you need to factor the equation.
y=16x^2+64x
y=-16x(x-4)
The zeros are x=0 and x=4
Therefore the answer is D, after 4 seconds.
Hope this helps!
