This is a parabola, first, locate the line of symmetry.
the line of symmetry is x=-b/2a
in this case, b=-2, a=-1, so the line of symmetry is x=-1
when x=-1, f(x)=-(-1)²-2(-1)-3=-2
locate the point (-1,-2) on the grid. this point is the vertex.
get two pairs of points with x=-1 as the symmetry line:
(0, -3) and (-2, -3); (1,-6) and (-3,-6)
connect these five points into a parabola, stick out at the ends because it will extend forever downward.
Answer:
She will have $73.5 in 1 year
Step-by-step explanation:
She has $70 and the interest rate is 5% so we need to add 5% to the initial value
x = $70 + $70 * 5%
5% = 5/100
x = $70 + $70 * 5/100
x = $70 + $3.5
x = $73.5
She will have $73.5 in 1 year
Answer:
< -18 or v ÷ -9 < -18
Step-by-step explanation:
"The quotient" means that it is a division problem. That means you have to divide.
Less than is a symbol that stands for *The number is less than the other number*
Answer:
-445/month
Step-by-step explanation:
I think that what you would do is divide -5,341 by 12, which gives you -445
If you have two statements p and q and
is
true, then
is also true.
In your case, statements are p - "x is odd" and q - "2x is even".
Then
- "x is not odd" and
- "2x is not even."
Hence
sounds as: "If 2x is not even, then x is not odd".
Answer: correct choice is D.
