Answer:
undefined
Step-by-step explanation:
slope = ((y2-y1)/2) / ((x2 - x1 )/2)
since x1 = x2
so x2 - x1 = 0
then ((y2-y1)/2) / 0 = undefined
X = number of loads
company A : 20x + 8
company B : 24x + 4
20x + 8 = 20(5) + 8 = 100 + 8 = 108 (company A)
24x + 4 = 24(5) + 4 = 120 + 4 = 124 (company B)
company A charges less
20x + 8 = 20(9) + 8 = 188
24x + 4 = 24(9) + 4 = 220
220 - 188 = $ 32 bucks is saved by using company A
Hi there!
I'm guessing you want to know what the equation of the slope-intercept line is.
The general equation for the slope-intercept line looks like this:
y = mx + b
Where "m" is the slope and "b" is the y-intercept.
Since we know what the slope is and we have the coordinates of a point, you can replace the slope and the value of the coordinates "x" & "y" in the equation and solve for "b" in order to find the whole equation :
y = mx + b
-1 = -1/2(10) + b
subtract "b" from each side of the equation
-1 - b = -1/2(10)
Add 1 to each side of the equation
-b = -1/2(10) + 1
-b = -5 + 1
-b = -4
Divide each side of the equation by -1
b = 4
Since you now know the value of "b" you can go ahead and write the slope-intercept equation with the slope in it and the y-intercept value also (b) :
y = -1/2 + 4
There you go! I really hope this helped, if there's anything just let me know! :)
Height, h of the cone is 3V/πr²
Step-by-step explanation:
- Step 1: Find formula for height.
Volume, V = 1/3 πr²h, where r is the radius and h is the height of the cone.
Cross-multiply to find formula for height.
∴ Height, h = 3V/πr²
