I'm assuming this is what you meant!
Rewrite the problem: B - 4 > = -1
B > 3
+ 3➡+3
__ ___
3b 9
Take off the 3
This is your plot ➡B - 3.0 > 0
We have one solution in this problem!
B > 3
Width = 9 cm
area = 63 cm^2
length = area ÷ width = 63 ÷ 9 = 7cm
perimeter = 2(l+b) = 2(7+9) = 32 cm
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
-4x change subtraction to addition and turn 9x to -9x and then add and get -13x
