Find the vertex using vertex formula
-b ÷ 2a -8 ÷ -2 x = 4 for y plug in
F(x) = -(4)² + 8(4) + 9
= -16 + 28 +9
= 12 + 9
= 21
(4,21)
vertex form
y = -(x - 4)² + 21
so that means it will flip down - means flip down
so vertex represents a maximum point
Answer:
x = 9
Step-by-step explanation:
The perimeter is the sum of the lengths of the base and the two equal legs:
51 = x + 2(3x -6)
51 = 7x -12 . . . . . eliminate parentheses
63 = 7x . . . . . . . . add 12
9 = x . . . . . . . . . . divide by 7
Answer:
26=9s+4s
13s=26
s=26/13
s=2
Step-by-step explanation:
hope it is helpful for you if it is follow me
Answer:
SUPER SIMPLE =
if r//s then the two angles which in this case are 110 and 80 should be equal but clearly in this case are not so the the lines r and s arent parallel to each other .
