Step-by-step explanation:

First of all, we need to figure out which "category" each observation belongs to. Then we need to count the number of observations in each category and enter that count in the table.

I have numbered the categories 1-4 from top to bottom so that you can see how I have assigned observations to categories. The numbers on the right in the table are the ones the problem is asking for. (6, 2, 3, 3)

A student said thst the distance between (-5,7) and (3,7) is 2 units<br>is the student correct?

Usimov [2.4K]

No.

The distance is |-5 -3| = 8 units. (Y-coordinates are the same, so the distance is measured entirely in the x-direction. Distance is non-negative.)

What is the answer for y=2x-5 and 4x-y=7

Dvinal [7]

Substitute the first equation into the second equation. You will get:

4x - (2x - 5) = 7

Distribute the negative sign into the parenthesis:

4x - 2x + 5 = 7

Simplify

2x + 5 = 7

Subtract 5 on both sides

2x = 2

x = 1

Now, substitute x = 1 into the first equation:

y = 2(1) - 5

y = 2 - 5

y = -3

The solution to the system of equations is (1, -3).

What is the solution to |x + 2| < 1?

Katyanochek1 [597]

Answer:

-3 <x <-1

Step-by-step explanation:

|x + 2| < 1

There are two solutions, one positive and one negative ( remember to flip the inequality for the negative)

x+2 <1 and x+2 > -1

Subtract 2 from each side

x+2-2 < 1-2 and x+2-2 > -1-2

x < -1 and x >-3

-3 <x <-1
