Hez is making a bookcase the boards that are used to make the bookcase are 13/16 inch thick hez found a board that is 1 1/4 inches thick by how much does hez have to reduce the thickness of the new board to match the other boards of the bookcase

Hez have to reduce the thickness of the new board by 35% to match the other boards of the bookcase

Solution:

The boards that are used to make the bookcase are inch thick  

Hez found a board that is inches thick  

Let us consider that he has to reduce the n% of board

Then, thickness – n% of thickness = required thickness

On solving we get,

On simplification,

Hence, he has to reduce the board by 35%

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
