The answer is -6
Because when x = -2, y = -6 on the graph
Answer: 32
Step-by-step explanation: You have divided 24 and 6 to get 4
Then 8 - 6 is 2
2 x 4 is 8
and last 24 + 8 = 32
Hope this helped don't forget to mark brainliest☺️
give me thanks and 5 stars

5 4
x = 18•4 / 5
72/5 = 14.4 final answer
Answer:
Step-by-step explanation:
Let's first put that polynomial in standard form by descending powers of t:
If we are looking for the times where the rocket is at a height of 26 m, we sub in a 26 for h(t) and factor to solve for t. First we get all the terms on one side of the equals sign and set it equal to zero.
That is a second degree polynomial so you can factor it however you are most comfortable to get the values of t are:
t = .51 sec and t = 10.29 sec
Since this is a polynomial, there will be 2 values of t for this time with y being the height and x being the time. The parabola is symmetrical about the vertex so there are 2 values of t (or x) that equal height (or y).
