i guess is by multiplying 3by the first equation and multiply 2by the second equation
Answer:
vertex =
(
4 , 25
)
Step-by-step explanation:
given a parabola in standard form y
= a
x
2
+
b
x
+
c
x
;
a
≠
0
then the x-coordinate of the vertex is
X vertex=-b/2a
y=-x2+8x+9 with a=-1 b=8 c=9
X vertex= -8/-2=4
substitute the value on the equation
Y vertex = -(4)squared+8(4)+9=25
2.5 hours, because 10 miles an hour times 2 = 20 plus half the time? 2.5
This is simple, cycle through the answers until you get 30 inches squared. The answer is height equals 5. 2x3x5=30
