The answer is C.
For a relation to be a function every x-value must be associated with one y-value. C has the x-value of 1 have two separate y-values. The others do not have an x-value that repeats.
Answer:
The equation of the line is y = 2x - 6
Step-by-step explanation:
To find the equation of this line, we first need to find the slope. To find a slope you need two ordered pairs, which you have here. The first is (5, 4) and the second is (3, 0) - which is the x-intercept of 3. Now that we have this, we can plug into the slope equation.
m(slope) = (y2 - y1)/(x2 - x1)
m = (4 - 0)/(5 - 3)
m = 4/2
m = 2
Now that we have the slope, we can use that and either point in point-slope form. Once we do that, we solve for y to get the equation.
y - y1 = m(x - x1)
y - 4 = 2(x - 5)
y - 4 = 2x - 10
y = 2x - 6
Answer:
6(w+3)(w-7)
Sorry if this is the wrong answer. But I hope you get a good grade on your test.
-8 is the value of this qustion <span />
The volume of the prism is (Length x Width x Height).
To make it easier to work with, let me write (L x W x H).
If you cut each dimension in half, then the volume is
(1/2 x L) x (1/2 x W) x(1/2 x H) .
It's pretty easy to rearrange that, and see what's going on:
1/2 x L x 1/2 x W x1/2 x H =
(1/2 x 1/2 x 1/2) x (L x W x H) =
( 1/8 ) x (original volume) =
( 1 / 2³ ) x (original volume)
Here's the general rule:
If you multiply all the linear dimensions of a drawing OR an object
by some factor 'K' , then
-- all of the linear features, like perimeter, diagonal, circumference,
diameter etc. are all multiplied by 'K' .
-- the 2-dimensional things on it, like area of the drawing, or surfaces
of a prism, sphere or any blob, are all multiplied by K² .
-- the 3-dimensional features, like volume of any prism, pyramid,
sphere, blob, ellipsoid, cylinder etc. are all multiplied by K³ .
