Answer: y $\leq$ 2x - 4

Formula is y = mx + b

m is the slope and b is the y-intercept.

Yes its a solution because the line passes through the point (2,0).

Answer:

Choice B.

Step-by-step explanation:

In a function, each x-coordinate can only appear in one single point. In a relation, if more than one point have the same x-coordinate, it is not a function.

Apply the vertical line test.

Imagine a vertical line starting at the left of the graph and moving to the right.

If the line in any position intersects more than one point of the relation, then the relation is not a function.

If the line in every position only intersects one point at a time, then the relation is a function.

Start with Choice A.

A vertical line starts at the left and moves right. It intersects point (-4, 3) by itself. Then it intersects point (-2, 1) by itself. When the vertical line gets to x = -1, it intersects two points, (1, -1) and (-1, 4). This means it is not a function.

Choice B.

Any vertical line in any position intersects at most one point at a time. Choice B is a function.

Choice C.

At x = -2 and at x = 2, a vertical line intersects two points. This is not a function.

Choice D.

At x = 0, a vertical line intersects two points. This is not a function.

Mnenie [13.5K]

Answer: n = 75; p = 30

Explanation: (a) 5p + 4n = 450 where p is for pen and n is for notebook.

(b) 10p + 3n = 525

We can use the elimination method to solve these two equations.

1. Multiply the first equation by 2 so that 10p will cancel out:

2(5p + 4n = 450)

- 10p + 3p = 525

10p + 8n = 900

- 10 p + 3n = 525

5n = 375

2. Divide by 5 to get n alone: n = 75

3. Plug 75 into the first equation: 5p + 4(75) = 450

5p + 300 = 450

4. Subtract 300 from 450: 5p = 150

5. Divide by 5 to get p alone: p = 30

We can test if this is correct by plugging our answers into the second equation:

10(30) + 3(75) = 525

300 + 225 = 525

525 = 525

This is a true statement, which means that our answers are correct.

Three students attempt to define what it means for lines lll and mmm to be perpendicular.

Vanyuwa [196]

Please find diagram attached

Answer and explanation:

Perpendicular lines are lines that meet at 90 degrees/ right angle.

The question seems to be incomplete but I will explain what perpendicular lines are in the context of lines lll and mmm, with some assumptions about the lines.

Assume that line III is 30mm long and line mmm is 25mm long, we say that line III is perpendicular to line mmm if line III meets line mmm at 90 degrees as we see in the diagram attached.
