Y = -3(x + 5)^2 - 4 Convert the equation from vertex form to standard form.

A. y = 9x^2 - 15x + 21

B. y = 3x^2 - 30x - 79

C. y = 3x^2 - 75x - 4

D. y = 9x^2 + 90x + 221​

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

look at photo

it would be 3 ÷by 6 because the number on each side
