He has the ability to get it agian after the third pass. He passes it across the circle to Joe, Joe passes to to Bill at his 4 o clock and then Bill can pass it back to the original passer
5(2x +8) = -8x + 4
Use distributive property:
10x +40 = -8x + 4
Subtract 40 from each side:
10x = -8x -36
Add 8x to each side:
18x = -36
Divide both sides by 18:
x = -36 / 18
x = -2
The number is -2
Use photo math it will help
Okay, so you know that something minus 20% of its total will equal 75%. You can set up an equation:
X - 0.2X = 75
0.8X = 75
X = 93.75 ,
meaning that the original price was $93.75
We can see that the y-intercept (the value of y when x=0) is -1 by looking at the table.
Now we just need the slope, or "m" of the linear equation.
m=(y2-y1)/(x2-x1) in this case:
m=(-2--1)/(1-0)
m=-1/1
m=-1
Now that we know m and b of y=mx+b we can say the line is:
y=-x-1
So this is a linear equation, y=-x-1
