4x^2 = 12x
4x^2 - 12x = 0
4x(x - 3) = 0
4x = 0
x = 0...not this one
x - 3 = 0
x = 3 <== ur number
Answer:
variables look like letters of the alphabet.
I hope this helps
Answer:
y = 5x
Step-by-step explanation:
-------------------------------------------
Define x:
-------------------------------------------
Let the shorter piece be x.
Shorter piece = x
Longer piece = 6x
-------------------------------------------
Construct equation:
-------------------------------------------
x +6x =35
7x = 35
x =5
-------------------------------------------
Find the length:
-------------------------------------------
Shorter length = x = 5 feet
Larger length = 6x = 6(5) = 30 feet
-------------------------------------------
Answer: The shorter piece is 5 feet.
-------------------------------------------
Step-by-step explanation:
Slope is the ratio of the vertical and horizontal changes between two points on a surface or a line.
If coordinates of any two points of a line are given then the rate of change is the ratio of the change in the y-coordinates to the change in the x-coordinates.
