The domain of the graph is {-3, -1, 1, 4}. The range of the graph is {-4, -1, 1, 4}

The domain of the set of ordered pairs is {-4, -3, 1}. The range of the set of ordered pairs is {1, 3, 4}

====================================================

Recall that the domain is the set of allowed x values. All we do is list the unique x coordinates of each point which are -3, -1, 1 and 4. The range is the set of y values so we just list the unique y coordinates of each point which are -4, -1, 1 and 4.

The same will happen with the other problem as well. The set of points listed is pretty much identical to the first problem, but the points haven't been graphed, but instead their coordinates have been listed out. The first coordinate is the x coordinate. The second coordinate is the y coordinate. Each point is in the form (x,y).

The ratio of boys to girls in Mrs. Ronilo's math class is 3 to 2. What percent of the class is boys? A) 33% B) 40% C) 60% D) 66%

nikdorinn [45]

Answer:

C) 60.

Step-by-step explanation:

Okay, I do math a little bit different than other kids... No worries though, its still correct.

First, find out how many times five can be put into a hundred. You should have gotten 20.

Now, we can use the twenty we got. Multiply 20 by the ratio of the boys. So 20 * 3 = 60.

Girls would be

20 * 2 = 40.

Those two numbers add up to a hundred so its all good. ^-^

Write a linear equation. Explain it in number please! 20 points!!!

juin [17]

To find a linear question, we must have two points on the line and we must know the slope.

Let us choose two points at random:

(-6,12) and (-5,14)

Now let us find the slope of the linear line:

$m = \frac{y2-y1}{x2-x1} =\frac{14-12}{-5--6} = 2$

So the slope is 2.

Now let us set up the equation which now requires only one point and the slope

let us use the point (-6,12) and the slope of 2

$y-12 = 2(x+6)\\y = 2x +12 +12\\y= 2x +4$

So the linear line is y = 2x + 4.

Hope that helps!

How do I solve 28.8=18x

kolezko [41]

28.8 = 18x....divide both sides by 18, eliminating the 18 on the right side
28.8 / 18 = x
1.6 = x <==
