Well 42 divided by 2 is 21. than to double check you can do 21 plus 21 equals 42.
Answer:
She would need to complete 5.57 each noght to reach her goal of 100%.
Step-by-step explanation:
39/7 is equal to 5.57
Domain: (-6, 0, 3) Range: (-9, -7, 3, 5)
To find the vertex, you need to find the axis of symmetry first.
In order to find the axis of symmetry we have to do -b/2a.
In our case, the b is -8 and the a is 1.
Plug it in.
-(-8)/2(1)
8/2 = 4
Our axis of symmetry is 4.
Now, we plug it into the equation to find the rest of the vertex.
y = 4^2 - 8(4) + 1
y = 16 - 32 + 1
y = -16 + 1
y = -15
Put it together.
Our vertex is (4,-15).
