Valentin [98]

Answer:

Officers can be chosen in 5,814 different ways.

Step-by-step explanation:

Given that the bowling team at Lincoln High School must choose a president, vice president, and secretary, to determine, if the team has 19 members, in how many ways could the officers be chosen, the following calculation must be performed:

19 x 18 x 17 = X

342 x 17 = X

5.814 = X

Therefore, officers can be chosen in 5,814 different ways.

Find the value of n that makes the equation -2=n+10 true.
VMariaS [17]

Given:

-2=n+10

To solve, we need to get n isolated on one side. To do this, subtract 10 from both sides. This will cancel the +10 on the right side and give us -12 of the left, leaving us with:

-12=n or n=-12


If you want to check your answer, plug in -12 for n.

-2=-12+10

-2=-2

The statement is true, therefore, n=-12.

3. Given the graph below, determine whether each statement is true or false.
MaRussiya [10]

Answers:

  1. True
  2. True
  3. True
  4. False
  5. False

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

Explanation:

In this context, a zero is another term for x intercept or root. This is where the graph either touches or crosses the x axis. This occurs in three locations: x = -3, x = 2, and x = 0. So those are the three roots. That makes the first three statements true, while the remaining two others are false.

Side note: x = 0 doesn't always have to be involved. Its quite possible to have x = 0 not be an x intercept. The term "zero" is a bit misleading in that regard. I prefer either "root" or "x intercept" instead.
