Answer:
I think 3.125 I'm not 100 percent sure tho
Answer:
x = -2/9
Step-by-step explanation:
27x = 9x − 4
Subtract 9x from each side
27x-9x = 9x-9x − 4
18x = -4
Divide each side by 18
18x/18 = -4/18
x = -4/18
Divide the top and bottom by 2
x = -2/9
Answer:
It will cost the school $60
Step-by-step explanation:
In order to find this, set up a proportion.
$18/15 dozen = $x/50 dozen
Now cross multiply to solve
50 * 18 = 15 * x
900 = 15x
60 = x
Answer:
The correct option is;
Reflection over the y-axis
Step-by-step explanation:
An even function is a function that satisfies the following function equation;
f(x) = f(-x)
Therefore, for an even function, we have;
f(x) - f(-x) = 0
Which gives that the values of f(x) of the even function is the same upon reflection about the y-axis whereby the values of x changes from x to -x
Therefore, the symmetry of an even function is about the y-axis
However, an odd function is a function that satisfies the following function equation;
f(-x) = -f(x)
Therefore, reflection across the y-axis will result in an inversion of the odd function such that the odd function is not symmetrical about the y-axis as we have;
f(-x) = -f(x) ≠ f(x) which simplifies to f(x) ≠ f(-x).
The equation of a parabola is given by
where
is the vertex.
We have the vertex is (-3,-2) so we have
and
Substituting -3 and -2 into the
Hence, the correct answer is
option D
