Ok, so user says that it should be solve for vertex not vertex form
(x,y)
to find the vertex of
y=ax^2+bx+c
the x value of the vertex is -b/2a
the y value is found by plugging in the x value for the vertex back into the original equation and evaluating
y=-2x^2-12x-28
a=-2
b=-12
xvalue of vertex is -(-12)/(2*-2)=12/-4=-3
x value of vertex is -3
plug backin for x
y=-2x^2-12x-28
y=-2(-3)^2-12(-3)-28
y=-2(9)+36-28
y=-18+8
y=-10
yvalue is -10
x value is -3
vertex is (-3,-10)
Answer:
45/3 or 15 simplified

so b. 15
Answer: 104.77 $ without coupon
94.77 $ with coupon
Step-by-step explanation:
25.99 Times 3 = 77.97 $
5.65 times 2 = 11.3 $
77.97+11.3=89.27 $
89.27 + 15.50 = 104.77 $
104.77 - 10 dollars of coupon = 94.77 $
