Answer: 5
Step-by-step explanation:
First you would add in the y. 2x+2(12-3x)=4
Then you would multiply the 2 into (12-3x) . 2x + 24 - 6x = 4
After that you will subtract the 24 and move it to the other side. 2x -6x = -20
Then you put together like terms. -4 = -20
Then divide to get 5.
Answer:
Width = 696.
Length = 697.
Step-by-step explanation:
Let the width be x, then the length = x+1 feet.
Using the Pythagoras Theorem:
x^2 + (x + 1)^2 = 985^2
x^2 + x^2 + 2x + 1 = 985^2
2x^2 + 2x - 970224 = 0
Using the quadratic formula:
x = [-2 +/- √(2^2 - 4*2*-970224)] / (2*2)
x = 696, -697(we ignore the negative root).
The general equation for a straight line is
![y=mx+b](https://tex.z-dn.net/?f=y%3Dmx%2Bb)
, where m is the slope, and b is the y-intercept. Plugging in numbers, your equation will be
![y=\frac{2}{3}x-4](https://tex.z-dn.net/?f=y%3D%5Cfrac%7B2%7D%7B3%7Dx-4)
