Answer:

y= 2x-3 m=2 b= -3

Step-by-step explanation:

we distribute 2(x-2)

y-1 = 2(x-2)

y-1 = 2x-4

then add one to both sides

y-1= 2x -4

+1 +1

since it is negative four and you are adding one it would be -3

y= 2x -3 that is your slope intercept form.

y= mx +b so m=2 and b= -3

Find the volume of a pyramid with a square base, where the side length of the base is

valina [46]

Answer:

Volume = 1114.1 $in^3$

Step-by-step explanation:

Recall that the formula for the volume of a pyramid is given by:

$Volume=\frac{1}{3} \,B\,*\,H$

where B is the area of the pyramid's base (in our case a square of side 12,8 in), and H the pyramid's height (in our case 20.4 in).

Then the square base of the pyramid has an area given by: $(12.8\,\,in)^2=163.84\,\,in^2$

Finally,we can now write the volume of the pyramid as:

$Volume=\frac{1}{3} \,B\,*\,H\\Volume=\frac{1}{3} \,(163.84)\,*\,20.4\,\,in^3\\Volume=1114.112\,\,in^3$

Rounding the answer to a tenth of a cubic inch, we get:

Volume = 1114.1 $in^3$
