Answer:
(x + 3)(x - 16)
Step-by-step explanation:
I hope this helps.
Given:
Number of $2 increase in price Revenue
1 1045
3 1105
5 1125
7 1105
9 1045
Plot these values in an x-y plane and observe the trend. From the illustration, locate the vertex. The vertex of the parabola is (3, 1125). Therefore, the y value of the vertex is 1125.
First find the slope, so subtract the y1 and 2 then same thing with x. -7-1=y. -2-(-3)=x. y is -8 and x is 1. divide -8 and 1. which gives you -8. SLOPE is -8. THE FORMULA for slope intercept form is Mx+B=y first insert the numbers then solve. need any more help use the app socratic and photo math
5 feet multiplied my 5 feet equals 25 feet
Sorry if my answer might be incorrect<span />
The system of the linear systems of equation using substitution is;
- x = 2, y = 2
- x = -20, y = -1
<h3>Linear equation</h3>
3x-y=4
x+2y=6
from (2)
x = 6 - 2y
substitute into (1)
3x-y=4
3(6 - 2y) - y = 4
18 - 6y - y = 4
- 6y - y = 4 - 18
-7y = -14
y = 2
Substitute into
x+2y=6
x + 2(2) = 6
x + 4 = 6
x = 6 - 4
x = 2
2. 2x-y= -39
x+y= -21
From (2)
x = -21 - y
substitute into
2x-y= -39
2(-21 - y) - y = -39
-42 - 2y - y = -39
- 2y - y = -39 + 42
- 3y = 3
y = 3/-3
y = -1
substitute into
x+y= -21
x + (-1) = -21
x - 1 = -21
x = -21 + 1
x = -20
3. 2x+y =11
6x-5y =9
