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
Answer:
We start with 0 + 40.
1. 0 + 40
2. 1 + 39
3. 2 + 38
4. 3 + 37
.....
keep going....
.....
19. 18 + 22
20. 19 + 21
21. 20 + 20
There are 21 pairs of whole numbers that have a sum of 40.
Step-by-step explanation:
hope this helps :)
The answer would be D....
Answer:
Hope, Casey, Daniela
Step-by-step explanation:
tbh I just guessed, but that is the answer
If 36x^3a+45xa^2=9a() then 9a is a factor the other factor, (), is the left side divided by 9a
(36x^3a+45xa^2)/(9a)
4x^3+5xa
So the () term is (4x^3+5xa)
