WILL MARK BRAINLIEST DUE IN 20 MINUTES!! A quadratic equation can be written in the form y = a(x – 5)2 + k, where (h, k)
is the vertex of the parabola. This form can be used to determine the minimum y-
value of the related function. Which is the minimum y-value of
y = 5x2 – 20x + 24?

A: -20
B: 2
C: 4
D: 16

Step-by-step explanation:

Given function:

Convert the equation into vertex form:

Vertex is (2, 4) at which the minimum y-value is 4

Correct choice is C

-3.5 is the distance.

i've had this question so choose the one in the absolute value sign.

we can set up an equation to find the girls' ages. the equation is         28=0.5x-5+x. (comment if you need me to explain how i got this equation.) so, you add x and 0.5x to get 1.5x and add 5 to each side. your new equation is 33=1.5x. now divide both sides of the equation by 1.5 to get 22=x. because x is mary's age, to find jasmine's age we subtract mary's age from 28. we find that mary is 22 years old and jasmine is 6 years old.
