equals 0.40
to calculate, 15 divided by 6 equals 0.40.
Answer:
4 dollars per pair of socks.
Step-by-step explanation:
You already determined that x and y have a proportional relationship, as y is four times the x value. Therefore, when x is 1, that means one pair of socks will be four dollars.
Another way to solve this is by forming a linear equation.
y = 4x
Any number plugged into x to represent pairs of socks will give the cost, y.
For example: y = 4(7), which simplifies to y = 28.
This means that for every one pair of socks, it costs four dollars.
M =kw+b general form
1. k should be negative because the line is going down when x increases
2. b is y intercept , b=250
slope= - 50/2 =-25
m=-25w + 250
correct choices
1) m=250-25w
4) m +25w=250, because can be written as m=-25w =250
