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.

Answer:

34a^2 + 21a - 20

Step-by-step explanation:

(12a^2 + 6a -8) - (-22a + 12 - 15a)

12a^2 + 6a - 8 + 22a + 12 - 15a

34^2 + 6a - 8 - 12 + 15a

34^2 + 21a - 20

0.6w = 0.48 how u do this
vovangra [49]

A variable next to any number means to multiply, so we would do the inverse operation -- We would divide 0.48 by 0.6, which is 0.8. Therefore, W=0.48. To check your work, multiply 0.6 by 0.8, and what do you know? It's 0.48! :)

10) Choose the solution for each linear system.
hodyreva [135]

Answer:

<h2>10.  C. (2, -1)</h2><h2>11.  B. (-2, -4)</h2>

Step-by-step explanation:

10.

\left \{ {{x-2y=4} \atop {4x+2y+6}} \right.

The y values cancel out if you add the equations

5x = 10

x = 2

plug in x

2 - 2y = 4

-2y = 2

y=-1

Answer: C. (2, -1)

11.

\left \{ {{6x-2y=-4} \atop {-4x+3y=-4}} \right.

In order to get terms to cancel out, multiply the top by 3 and bottom by 2

\left \{ {{18x-6y=-12} \atop {-8x+6y=-8}} \right.

The y values cancel out if you add the equations

10x = -20

x = -2

plug in x

6(-2) - 2y = -4

-12 - 2y = -4

-2y = 8

y = -4

Answer: B. (-2, -4)
