1) Find x, if 1/3 of x is 14
BartSMP [9]

"of" means multiply      and         "is" means equal

1. \frac{1}{3}x = 14

                                x = 14(3)      <em>multiply both sides by 3 to isolate "x"</em>

                                x = 42

2. \frac{1}{5}x = 14

                                x = 14(5)      <em>multiply both sides by 5 to isolate "x"</em>

                                x = 70

3. \frac{2}{5}x = 14

                                2x = 14(5)      <em>multiply both sides by 5 </em>

                                2x = 70

                                  x = 35         <em>divide both sides by 2 to isolate "x"</em>

4. \frac{7}{8}x = 14

                                7x = 14(8)      <em>multiply both sides by 8 </em>

                                7x = 112

                                  x = 16         <em>divide both sides by 7 to isolate "x"</em>

Find a point-slope form for the line with slope 1/5 and passing through the point (- 4. - 8).
andrew11 [14]

Answer:

y+8 = 1/5(x+4)

Step-by-step explanation:

The point slope form of a line is

y-y1 = m(x-x1) where m is the slope and (x1,y1) is a point on the line

y- -8 = 1/5(x - -4)

y+8 = 1/5(x+4)

Madame Pickney has a rather extensive art collection and the overall value of her collection has been increasing each year. Thre
grigory [225]

Answer:

About $1,178,974

Step-by-step explanation:

Alright, the sequence we have right now is:

500,000       550,000      605,000

We want to find the common ratio, so let's divide 550,000 by 500,000 and see if we get the same value as 605,000 divided by 550,000:

550,000/500,000 = 1.1

605,000/550,000 = 1.1

Now, we know that r = 1.1. We also know the first term is: a_1 = 500,000.

We use the explicit rule of a geometric sequence:

a_n=a_1*r^{n-1}

Here, we want to find a_{10} , which means that n = 10. We know r and a_1, so we just plug in these values:

a_{10}=500,000*(1.1)^{10-1}=500,000*(1.1)^{9} ≈ 1,178,973.85 ≈ 1,178,974

Thus, the answer is about $1,178,974.

Hope this helps!
