Answer:
See below and attached picture
Step-by-step explanation:
a. To graph the equation set y = 0 and solve for t.
y = -16t² + 100
0 = -16t² + 100
100 = -16t²
6.25 = t²
+/- 2.5 = t
Mark the points (-2.5,0) and (2.5,0). Then mark the highest point at (0,100). Draw a curve or parabola to connect the points.
b. Domain is the set of t values. This is the time it's in the air. The graph shows it at height 100 at t = 0 and at height 0 at t = 2.5. The domain is [0, 2.5].
Range is the set of y values. This is the height of the object. The graph shows it at height 100 at the beginning and then falls to height 0. The range is [0,100].
c. The graph has the point (1,84). This means it was at height 84 feet at 1 second.
d. The graph has a point about (1.75, 50). This means at about 50 feet it was 1.75 seconds.
e. The shingle is at height 0 feet at 2.5 seconds when it crosses the x-axis.

Answer:
y = x + 6
Step-by-step explanation:
y = x + b
when x = 0, y = 6. so....
6 = (0) + b
6 = b
so, y = x + 6
Answer:
Lev is incorrect because (9, 4) is not a solution to the equation.
Step-by-step explanation:
We are given the equation: 3y - 2x = 19
When we are to check if an ordered pair is a solution to an equation, we substitute the pair in the equation and compare the RHS and LHS.
If they come to be equal then we can say that the given pair is indeed a solution to the equation.
So, here, RHS = 19
LHS = 3(4) - 2(9) = 12 - 18
= -6
19
i.e., LHS ≠ RHS
So, we can say that (x, y) = (9, 4) is not a solution to the given equation.
Answer:
7
Step-by-step explanation:
![\frac{5}{5} + 6 = 1 + 6](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B5%7D%20%20%2B%206%20%3D%201%20%2B%206)
To solve this you just have to replace the letters with the corresponding numbers. 5/5 = 1 and 1+6 = 7
So your answer is 7!
