Remember, you can do ANYTHING to an equation as long as you do it to both sides

x+x+2+2x=-2
regropu to add x's
1x+1x+2x+2=-2
4x+2=-2
minus 2 from both sides
4x+2-2=-2-2
4x+0=-4
4x=-4
divide both sides by 4
4x/4=-4/4
(4/4)x=-1
1x=-1
x=-1

What is the volume of the figure?
Arlecino [84]
So the equation for volume is V=Bh
V is volume, B is area of the base, and h is height
To find the area of the base we need to multiply the height times the base of the triangle and divide by 2
(16*12)/2=96
Now multiply times the height
or 24
The volume of the prism of 2304 mm^3

1. Calculate the equation of the line through the points (1, 1), (4, 3), (10, 7) and (40, 27).
Gala2k [10]

Answer:

y = (2/3)x + 1/3

Step-by-step explanation:

Check that a single straight line will actually go through all four of these points.  Going from (1, 1) to (4, 3), the 'rise' is 2 and the 'run' is 3, which would make the slope, m, equal rise/run = 2/3.  Going from (4,3) to (10, 7), m = rise/run = 4/6 = 2/3 (again).

Let's find the slope-intercept form of the equation of this line:  y = mx + b

Arbitrarily choose the point (1, 1).  Here x = 1, y = 1 and m = 2/3.  Then

we have

1 = (2/3)(1) + b, or 1 = 2/3 + b, so that b must be 1/3.

The equation in question is y = (2/3)x + 1/3
