-4-6= -10
-10 = Y
-4 = X
Therefore the answer is (-4,-10) which isn’t on the options
Answer: To find the slope, you divide the difference of the y-coordinates of 2 points on a line by the difference of the x-coordinates of those same 2 points .
Step-by-step explanation:
Answer:
Step-by-step explanation:
Given

ball is dropped from a height of 
therefore 

Time taken to fall half the distance to the ground level i.e. 

arranging we get



(b)Time taken to fall
i.e. h=0




Answer:
<em>9 is a zero of h(x).</em> C. Correct
Step-by-step explanation:
We want to find the zeros of the function

The zeros are the values of x that make h(x)=0, thus we need to solve the equation:

Factoring:


This equation has 3 solutions:
x=9, x=-9, x=-4
A. 0 is not a zero of h(x). Incorrect
B. 4 is not a zero of h(x). Incorrect
C. 9 is one of the zeros of h(x) calculated above. Correct
D. 81 is not a zero of h(x). Incorrect
