If a certain cannon is fired from a height of 9.7 meters above the ground, at a certain angle, the height of the cannonball above the ground, h, in meters, at time, t, in
seconds, is found by the function h(t) = -4.912 + 30.5t +9.7. Find the time it takes
for the cannonball to strike the ground.

expression #3 is not equivalent. the others are.

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic
