First you want to use the distributive property. So, $9*p-(9*4)=-18$ . Which equals $9p-36=-18$ . Next use the addition property of equality to make your first step to isolate variable p. Which equals $9p-36+36=-18+36$ . Then simplify the equation down to $9p=18$ . Lastly, is the division property of equality $(9p)/9=18/9$ . Once again simplify to $p=2$ . Always make sure to pull your answer back into the original equation to see if the answer is correct.

$9(2-4)=-18$

$9(-2)=-18$

$-18=-18$

Step-by-step explanation:

9(p-4) = -18

9p - 36 = -18

9p = -18 + 36

9p = 18

p= 18/9

p = 2

Check:

9 ( 2 - 4 ) = - 18

9 (-2) = - 18

- 18 = - 18

How many ways can a committee chairman choose 4 people for a subcommittee if there are 12 members on the whole committee?

Marina86 [1]

A group of k elements can be chosen from a group of n elements in $\frac{n!}{k!(n-k)!}$ ways.

$(^{12} _4)=\frac{12!}{4!(12-4)!}=\frac{12!}{4! \times 8!}=\frac{8! \times 9 \times 10 \times 11 \times 12}{2 \times 3 \times 4 \times 8!}=\frac{9 \times 10 \times 11 \times 12}{2 \times 3 \times 4}= \\ \\
=3 \times 5 \times 11 \times 3=495$

The answer is B. 495.

Point B is on the graph of the function f(x) = -3x^2. If the x-coordinate of point B is 2, which ordered pair gives the location

Oksana_A [137]

<span>f(x) = -3x^2</span>
insert x=2
y=-3*2^2
y=-3*4
y=-12
so your pair is (2,-12)
