Answer:
5x + 2 - 2(4x - 2)
Step-by-step explanation:
-2 x 4x= -8x
5x-8x=-3x
-2 x -2= 4
4+2=6
-3x+6
hope this helped ^ ^
The slope-intercept form of a line is:
y=mx+b, where m=slope and b=y-intercept (value of y when x=0)
First you must find the slope, or m value.
m=(y2-y1)/(x2-x1), which is the change in y divided by the change in x. In this case:
m=(5--3)/(-4--1)
m=(5+3)/(-4+1)
m=8/-3
m=-8/3
So far our line is:
y=-8x/3+b, we can now solve for the y-intercept, or b, using any point on the line, I'll use (-4,5):
5=-8(-4)/3+b
5=32/3+b
15/3=32/3+b
15/3-32/3=b
-17/3=b
So now we know the value for both terms in our line:
y=(-8x-17)/3
Answer:
not much
Step-by-step explanation:
Answer:
Size 2 with 3.1 units price
Step-by-step explanation:
Size 1:
A 10.15-ounce package costs 2.98.
Units price of size 1 = 10.15 / 2.98
= 3.4060
Approximately 3.4
Size 2:
A 27.8 -ounce package costs 8.99.
Units price of size 2 = 27.8 / 8.99
= 3.0923
Approximately 3.1
The best size which is better buy based on unit price is size 2 with 3.1 units price
