Answer:
D
Step-by-step explanation:
The circle is filled in and the numbers are going lower so x is less than or equal to 7. I hope this helps and have a great day!
Answer:
A
Step-by-step explanation:
Remember that the x-value of the vertex when an equation is given in standard form can be found with the equation
. So, we can take the coefficients from the equation and plug them in.

Now we know that the x-value of the vertex is 8. Next, the equation for the y-value is
, where h is the x-value of the vertex (8).

So the vertex is (8,-1).
Finally, the axis of symmetry is the x-value of the vertex, also called h.
Final answer, vertex: (8,-1) and axis of symmetry: x=8
Hope this helps!
Answer:
9x^2 + 9x -70
Step-by-step explanation:
Use the distributive property to solve
(3x-7) (3x+10)
multiply 3x x 3x = 9x^2
multiply 3x(-7) and 3x(10)
add -21x + 30x = 9x
multiply -7 x 10 = -70
2.95x5=14.75 7% of 14.75=1.0325 14.75+1.0325=15.7825 or just $15.78
Ask: Which two numbers add up to -12 and multiply to 32?
-8 and -4
Rewrite the expression using the above
<u>= (y - 4)(y - 8)</u>
