Answer:
Convert these mixed numbers into improper fractions.
-45/8 + 7/2
Find the common denominator which is 8 in this case.
-45/8 + 7(4) / 2(4)
-45/8 + 28/8
Which equals -17/8
or -2 1/8
Answer:
A is the best answer.
Step-by-step explanation:
A is. It can be written as y [ or v] = -2(x + 3)^2 + 7 which is the pure form of a vertex equation.
C doesn't work since that is a linear function. Nothing is squared.
D doesn't work. That is just the way an ordinary quadratic is written. (Standard form).
B doesn't work. The quadratic is written in factored form.
ANSWER
EXPLANATION
The vertex form of a quadratic function is given by:
From the given options, the first choice is
where a=-2, h=-3, and k=7.
Therefore the vertex is (-3,7)
Hence the first choice is the correct option.
