The number is 4/5 or 0.8.
let x be the number.
12 - 2x = 8x + 4
-12 -8x -8x -4
-10x = -8
-10x\-10 = -8/-10
x = 4/5 or 0.8
Slope intercept form is y=mx+b. In this case, I believe it's y= -5/6x -5/6.
Answer:
2.50 dollars.
Step-by-step explanation:
Given:
Will and his friends buy a large salad to share and several slices of pizza, p.
The graph given shows the total cost for lunch, c and slices of pizza,p.
p is marked horizontally, and c vertically.
Observing the points marked we find that for every increase of one slice of pizza, the cost i.e. c on vertical line increases by 0.50 times vertical grid.
Since each grid equals 5 dollars vertically, we find 1/2 grid increase is equal to increase of 1/2(5 ) =2.50 dollars.
Thus for increase of one slice of pizza, 2.50 dollars cost is increased.
