The slope and Y-Intercept for y=-x+2

katovenus [111]

Answer:

1 and 2

Step-by-step explanation:

slope is 1

y intercept is 2

basically base it off the equation y = mx + b

the m is the slope, but since in this case there is no number before x, you just put 1, since 1 times x is just x and thats why its left out

the b is the y intercept, so in this case its 2

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 $in^3$

From the sum of 3x^2-5x+1 and x^3 +3x - 1 subtract 2x^3 - 4x2

Mariana [72]

Answer:

it is -x^3 + 7x^2 -2x if you meant subtract 2x^3 - 4x^2 But if you meant subtract. 2x^3 - 4x +2 then the answer is -x^3 +3x^2 +2x -2
