Answer:

see below

Step-by-step explanation:

The first equation is in slope-intercept form, so you can see that the boundary line has a slope of -2 and goes through the point (x, y) = (0, -4). Since the comparison is "<", the line is dashed and shading is below it.

The second equation is that of a vertical boundary line at x=-3. It is solid, because the comparison includes the "equal" case. Shading is to the right of it, where x values are greater than -3.

Cmon man, your not even trying.

3(x+6) is x+6+x+6+x+6 or 3x + 3(6).

That simplified is 3x + 18

Answer:

1 7/18

Step-by-step explanation:

5/9 + 5/6 write all numerators above the least common denominator which is 18.

10+15/18 then you add the numerators which will make it 25/18 which alternative form will be 1 7/18, or in decimal 1.38

Which of the following represents the equation y = mx + b, where m is a positive integer, written in standard form?

babymother [125]

<h3>Answer:</h3>

B. mx−y=−b

<h3>Step-by-step explanation:</h3>

Start with ...

... y = mx +b

Subtract mx.

... -mx +y = b

You want the leading coefficient positive, so multiply by -1.

... mx -y = -b . . . . matches selection B

A net is pretty much a three dimensional shape unfolded into a flat construction. Imagine cutting the edges of a box and unfolding it so you can lay it flat on the ground. That would form a net for the 3D shape of the box.
In this case, 1 and 2 obviously aren't right since they would both involve triangles in their net. 3 is close, but the parts of the net wouldn't be completely equal. Therefore it has to be 4, the cube.
