Y = -2x^2
h = Xv = -B/2A = 0/-4 = 0.
k = -2*0^2 = 0.
V(0,0).
Use the following points for graphing:
Y = -2x^2.
(x,y)
(-2,-8)
(-1,-2)
V(0,0)

(2,-8)
Y = -2x^2 + 4.
h = Xv = -B/2A = 0/-4 = 0.
k = Yv = -2*0^2 + 4 = 4.
V(0,4).
(-2,-4)
(-1,2)

Answer:
16/15
Step-by-step explanation:
Ratio: 3/4 : 4/5
Whole number ratio: 15 : 16
You need to divide both sides by 15 so you can turn 15 to 1
Divide both sides of the ratio by 15: 1 : 16/15
So, for 1 pound of flour, you need 16/15 pounds of brown sugar for a cake.

C)
First, you can get rid of A and B because the y-intercept is 6 so it has +6 at the end
Next, the slope is rise over run, the graph goes up 2 and over 3 so it should be 2/3.
2/3x + 6
The value of the expression (1 + 13)2 - 2^9 is -484
<h3>How to evaluate the expression?</h3>
The expression is given as:
(1 + 13)2 - 2^9
Evaluate the expression in the bracket
(1 + 13)2 - 2^9 = (14)2-2^9
Remove the bracket in the expression
(1 + 13)2 - 2^9 = 28-2^9
Evaluate the exponent in the expression
(1 + 13)2 - 2^9 = 28-512
Evaluate the difference in the expression
(1 + 13)2 - 2^9 = -484
Hence, the value of the expression (1 + 13)2 - 2^9 is -484
