Answer:
(-2,-36)
Step-by-step explanation:
<u>1) Find the zeros of the parabola</u>
The zero-product property states that any value, when multiplied by 0 will equal 0. Therefore, to make y=0, either (x-4)=0 OR (x+8)=0.
Therefore, x=4 and x=-8.
<u>2) Find the x-coordinate of the vertex</u>
To do this, we take the average of our zeros.
Therefore, the x-coordinate of the vertex is -2.
<u>3) Find the y-coordinate of the vertex</u>
Plug the x-coordinate back into the original equation
Therefore, the y-coordinate of the vertex is -36.
Therefore, the vertex of the parabola is (-2,-36).
I hope this helps!
Answer:
30 or 780 is your answer for the first one. i dont know how to work out the answer for the 2 one im sorry :(
Step-by-step explanation:
13+12+5 = 30
13 x 12 x 5 = 780
I would go for 780
it seems more like to be the answer
Answer:
Graph the points, (2,18) (7, 24) and (16, 0)
Step-by-step explanation:
Going to the store takes 2 minutes for 18 blocks, which is the first point
He stays at the store for 2 minutes then takes 3 minutes to get to the bank which is 6 blocks away, add the time together and blocks, and you get the second point
He stopped at the bank for 3 minutes and the drove back home. It takes him 6 minutes to get back home, (24/6), add all the minutes together and you get 16.
(This is assuming the graph is y for blocks and x for minutes)
Answer:
The answer is D. (x-4)^2
Step-by-step explanation:
It has a horizontal shift of 4 to the right
Answer:
18
Step-by-step explanation:
3⋅6−2+2
Use PEMDAS = Parentheses, Exponent, Multiplication, Division, Addition, Subtraction
First we multiply, then add or subtract so,
18 - 2 + 2
Now we subtract,
16 + 2
Now we add,
18
