Answer:
8
Step-by-step explanation:
Y=ax²+bx+c
c is x-int =7 (0,7), so c=7
vertex=(-3,-2), another point (-6,7)
y=ax²+bx+7
-2=a(-3)²+b*(-3)+7, -2=9a-3b+7, ----> -9=9a-3b ---->-3=3a-b
7=a*(-6)²+b(-6)+7, ---> 0=36a-6b, ---> 0=6a-b
-3=3a-b
0=6a-b ----> b=6a
substitute b=6a in -3=3a-b, so
-3=3a-6a, ----> -3= -3a, a=1
substitute a=1, in b=6a, ---> b=6*1=6
y=ax²+bx+c
y=x²+6x+7

[ Explanation ]
Area Of Rectangle: Length * Width
2 4/5 * 1 1/5
=======================
Convert Fractions Into Mixed Numbers:
2 4/5 = 14/5
1 1/5 = 6/5
Multiply Across:
14 * 6
5 * 5
= 84/ 25
Simplify:
3 9/25
Step-by-step explanation:
<u>y</u> - <u>1</u> = <u>-</u><u>3</u>
x - 0 2
2y - 2 = -3x
2y = -3x + 2
