Answer:volume is lengthxwidthxheight
Step-by-step explanation:
Length=3
Width=7
Height=10
3x7x10=210 inches ^3
The domain is the set of possible inputs, i.e. the x-coordinates of the points.
Here those are 6, 1 and - 3 which in order is -3, 1, 6.
Then the answer is {-3, 1, 6}.
By the way note that this relation is not a function. Do you know why?
Because the image of -3 is not stated unambiguosly.
Well the area of a trapezoid is defined by the following formula:
A =

where b₁ and b₂ are the bases of the trapezoid and h is the height of the trapezoid.
Let's plug in what we know into this formula:
h = 7 the perpendicular distance between the two bases
b₁ = 15 the shorter parallel side
b₂ = 25 the longer parallel side made up of 4 + 15 + 6
so, A =

This is in square units of measure of course, so 140 in²
Answer:
(3, -3)
Step-by-step explanation:
When asked to solve by elimination, you put them on top of one another, like you're going to add it.
10x + 7y = 9
-4x - 7y = 9
See that 7y? You can cancel those out because one is negative, and one is positive. So those are gone. You finish adding the rest of the numbers as usual and solve for x.
6x = 18
x = 3
Take x, and plug it into either equation to find y.
10(3) + 7y = 9
7y = -21
y = -3
(3, -3)
Hope this helped!
