Step 2, because she added 4 only on one side.

Step 2 They were suppose to combine -3 - 4 to get -7, not use inverse operations (which should have been to the other side of the equation, not the same side) The right side should have said 6x -7 not  6x + 1

Permutations vs combinations(one step):
Bogdan [553]

Answer:

the expression is: ^{15}P_3=\frac{15!}{(15-3)!}

and 2730 different ways are possible.

Step-by-step explanation:

In the given question we have to choose a president, vice

president, and secretary.

Permutations are used when order is important so, as in the given question order is required. We would use permutations

The formula used is: ^nP_r=\frac{n!}{(n-r)!} where:

n=total number of objects

r=number of objects selected

In our case: n=15, r=3

Putting values and finding the answer:

^nP_r\\^{15}P_3=\frac{15!}{(15-3)!} =2730 \ ways

So, the expression is: ^{15}P_3=\frac{15!}{(15-3)!}

and 2730 different ways are possible.

At which values of x does the function F(x) have a vertical asymptote? Check all that apply.
Anton [14]

You get vertical asymptotes because the x-value causes you to try to divide by 0.  

If you look at the denominator, the x-values of 0, 1, and -5 all will make the denominator equal to 0, making the whole function explode.  

    You find these by solving  3x(x-1)(x+5)=0.

That's your answer: 0, 1, and -5
