Answer:
Red grapefruit costs more per pound.
Step-by-step explanation:
Red grapefruit
y =2x
This is in the form y= mx+b where m is the slope and b is the y intercept
The cost per pound is the slope, which is 2
The cost per pound is $2
Pink grapefruit
We need to find the slope
We have 2 points (0,0) and (4,4)
m = (y2-y1)/(x2-x1)
= (4-0)/(4-0)
=4/4
= 1
The slope is 1
The cost per pound is $1

Answer:
5/2 or 3/2
Step-by-step explanation:
(2x-3)(2x-3)
FOIL it out
4x^2-6x-6x+9
4x^2-12x+9=4x-6
add 12x to each side
4x^2+9=16x-6
add 6
4x^2+15=16x
4x^2-16x+15=0
use quadratic formula
