Answer:
5x+ 4y =20
Step-by-step explanation:
Slope = (y2-y1)/(x2-x1)
= (0-5)/(4-0)
= -5/4
We know the slope = -5/4 and the y intercept (x=0) y= 5
The euqation in slope intercept form is
y=mx+b whre m is the slope and b is the y intercept
y = -5/4 x +5
Multiply each side by 4 to get rid of the fraction
4y = 4*-5/4x + 5*4
4y = -5x+20
Add 5x to each side
5x+4y = 5x-5x+20
5x+ 4y =20
This is the standard form of a line
Ax + By =C
Answer:
B
Step-by-step explanation:
First you have to make it multiplication so you flip 5/2 around and the two “2’s” will cancel each other so it will be 17/5 or 3 2/5
Answer:
width = (21 - 2n) ÷ 2 or 21/2 - n
Step-by-step explanation:
To find Width
let's say width is x
so 2x + 2n = 21
take away 2n from both sides
then 2x = 21 - 2n
Divide both sides by 2 to get x on its own
x = 21 - 2n /2
therefore the width of the rectangle is 21 - 2n /2
