Given the following definitions:

sveticcg [70]

Step-by-step explanation:

First,

(A intersect B) = {1,2,4,5} intersect {1,3,5,7}

= {1,5}

Now,

A'n B = (A) - (A intersect B)

= {1,2,4,5} - {1,5}

= {2,4}

ella [17]

Answer:

17 students

Step-by-step explanation:

Given:

There are some students playing soccer.

Five students decided to join the game and now there are twenty-two students playing soccer.

Question asked:

How many students were originally playing soccer?

Solution:

Let initially number of students playing soccer = $x$

As given,

<u>After joining 5 more students, there are 22 students playing soccer, the equation will be:-</u>

$x+5=22$

Subtracting both side by 5

$x+5-5=22-5\\x=17\ students$

Hence, 17 students were originally playing soccer.

What is the relationship between the lines determined by the following two equations?

oksano4ka [1.4K]

Answer:

C. They are the same line.

Step-by-step explanation:

In order to compare the linear equations given, they need to be in the same form. The best form in order to evaluate slope and y-intercept is slope-intercept form, y = mx + b. Since the second equation is already in slope-intercept form, we need to use inverse operations to convert the first equation:

6x - 2y = 16 ---- 6x - 2y - 6x = 16 - 6x ---- -2y = -6x + 16

-2y/-2 = -6x/-2 + 16/-2

y = 3x - 8

Since both equations are in the form y = 3x - 8, then they are both the same line.
