Answer:
- (5, 9)
- (5, 6)
- (-5,-6)
- (5, -9)
- (-9, -5)
Step-by-step explanation:
Compare the given functions to the vertex form. Match parts to find the values of h and k. The vertex is (h, k).
Vertex form: f(x) = a(x -h)^2 +k
__
f(x) = 5(x - 5)^2 + 9; h = 5, k = 9; vertex: (5, 9)
f(x) = 9(x - 5)^2 + 6; h = 5, k = 6; vertex: (5, 6)
f(x) = 9(x + 5)^2 - 6; h = -5, k = -6; vertex: (-5, -6)
f(x) = 6(x – 5)^2 - 9; h = 5, k = -9; vertex: (5, -9)
f(x) = 6(x + 9)^2 - 5; h = -9, k = -5; vertex: (-9, -5)
2y-1.5y=2
0.5y=2
y=1
10x-5x=4
x=4/5
12 - 3 = 9 There are 9 cookies left.
The answer is choice B
The point (0,0) makes the first inequality true since
y >= x^2-4
0 >= 0^2-4
0 >= 0
is true
However, the point (0,0) does not make the second inequality true
y < 2x - 1
0 < 2(0) - 1
0 < -1
because 0 is not smaller than -1
Answer:
225
Step-by-step explanation:
if it is 1/3 off, then it means it's at 2/3 the price. now, you have to divide 450/2 to get the answer. 2/3 divided by 2=1/3
450/2=225, and thats how much money you will save
