for y=ax^2+bx+c
the xvalue of the vertex is -b/2a
and the y value is found by subsituting that for x
so
-b/2a
h(t)=2x^2+4x+7
a=2
b=4
-b/2a=-4/(2*2)=-4/4=-1
the y value
h(-1)=2(-1)^2+4(-1)+7
h(-1)=2(1)-4+7
h(1)=2+3
h(1)=5
(-1,5) is da vertex
308 slices would be sold.
38*8= 304, plus 4 slices in half a pizza makes 308 slices.
Terrance: 12 miles/1 hour
Jesse: 8 miles/1 hour
Are there any answers to choose from?
So if Jack was 10 years older than Priscilla and their ages combined equals to 170. I believe Priscilla is 80 and Jack was 90 cause 90+80=170
