There are no real numbers that can do that.
If you were to go far enough in high school math, you'd learn
about something called "imaginary" numbers. Using those, the
two numbers that add to 4 and multiply to 7 are
2 + 3.464 i
and
2 - 3.464 i .
The little ' i ' is the unit of imaginary numbers . . . the square root of -1 .
You won't ever get that far, since you already hate math
and you want everybody to know it.
Answer:
I would start the graph at (0,36) and go down 12, right 1 until you reach the end of the graph

Question:
Find the constant of proportionality k. Then write an equation for the relationship between x and y
Answer:
(a) 
(b) 
Step-by-step explanation:
Given
Solving (a): The constant of proportionality:
Pick any two corresponding x and y values
The constant of proportionality k is:
Solving (b): The equation
In (a), we have:
k can also be expressed as:
Substitute values for x1, y1 and k
Cross multiply:
Open bracket
Add 10 to both sides
First, do the distributive property: 4x-5=4x+2
This answer has no real solution. The term is no real numbers.
<span>x2 +8x +4y +4 = 0
</span>4y=<span> -x2 -8x -4</span>y = -.25*x^2 -2x -1
a = -.25b = -2c = -1
x position of vertex:
h = -b / 2a
h = 2 / 2*-.25h = 2 / -.5h = -4
y position of vertex:
k = ah^2 + bh + ck = -.25*-4^2 + -2*-4 + -1k = -4 +8 -1k = 3
VERTEX = (-4, 3)**************************************************************************
x value of focus =x value of vertex = -4
y value of focus =(1 (-b^2 -4ac)) / 4a
a = -.25 b = -2 c =-1
y value = (1 (-4 -4*-.25*-1)) / 4*-.25
y value = (1 (-4 -4*-.25*-1)) / -1
y value = (1 -4 +1) / -1y value = (-2 / -1)y value = 2
focus value = (-4, 2)
Answer is the last one.
