LUCKY_DIMON [66]
There are 116,280 ways to select the officers.

Since order is important, we use permutations:

P(20,4)=\frac{20!}{(20-4)!}=\frac{20!}{16!}=116280

Graph the system below and write its solution.
Diano4ka-milaya [45]

Answer:

See the graph attached. It has one solution: (6,-4)

Step-by-step explanation:

The slope-intercept form of a line is:

y=mx+b

Where m is the slope and b is the intersection of the line with the y-axis.

Given the first equation  y =\frac{-1}{2}x -1

You can identify that:

b=-1

Substitute y=0 to find the intersection with the x-axis

0 =\frac{-1}{2}x -1\\1(-2)=x\\x=-2

This line passes through the points (0,-1) and (-2,0)

Given the second equation:

-2 + y = -6

Solve for y:

y = -6+2\\y=-4

It passes through the point (0,-4).

Now, you can graph. See the figure attached.

It has one solution,which is the point of intersection of both lines:  (6,-4)

At a local fitness center, gym members pay $3 per workout with an annual membership fee of $140. Non-members pay $10 per workout
sleet_krkn [62]

Answer:

Yes the membership is worth it. If you have a membership you will pay $140 for the whole year. Then, it is $3 everytime you workout and if you plan on working out 2 times a month the total will be $72 dollars. So $72 + $140 is $212 yearly. If you don't get the membership you pay $20 a month because you will workout twice a month. So, 20 times 12 is $240. It may seem like it's not worth it but it actually comes out cheaper. So, yes I do think the membership is worth it.

Step-by-step explanation:

Hope you find this helpful. If you have questions feel free to ask.
