2 - 3 (2x - 5) = 6x + 1
2 -6x +15 = 6x +1  distribute the -3 to (2x -5)
-6x + 17 = 6x + 1  add 2 + 15
16 = 12x add the -6x to the positive 6x and subtract the 1 from 17
1 1/3 = x divide 16/12

If a1=1 and an+1=ann+2 for n≥1, determine a1,a2,a3, and a4
Sedbober [7]

Answer:

a1 =1

a2= 1/3

a3= 1/12

a4 = 1/60

Step-by-step explanation:

a(n+1) = an/(n+2)

if n=1

a(1+1)= a1/(1+2)

a2= a1/3

a2= 1/3

if n=2

a(2+1)= a2/(2+2)

a3= a2/4 = a2 × 1/4

a3= 1/3 × 1/4 = 1/12

if n=3

a(3+1)= a3/(3+2)

a4= a3/5 = a3 × 1/5

a4= 1/12 × 1/5 = 1/60

How many are 13 x 13 ?​
mote1985 [20]

Answer:

169

Step-by-step explanation:

13*13=169

We can split the two 13's up:

(10+3)(10+3)

Multiply 10 with 10, 10 with 3, 3 with 10, and 3 with 3.

Basically, just multiply every single term together.

100+30+30+9

100+69

169

Hope this helps!

In the picture it has the actual question that I am currently trying to solve right now.
Taya2010 [7]

Answer:

\begin{gathered} a)\text{ Amplitude = 4} \\ b)\text{ Period = 5} \\ c)\text{ Midline = 2} \end{gathered}

Explanation:

Here, we want to get the properties listed for the plot shown

a) Amplitude:

Amplitude\text{ = }\frac{max-min}{2}\text{ = }\frac{6-(-2)}{2}\text{ = }\frac{6+2}{2}\text{ = 4}

b) Period

The period is simply the distance from max to max or min to min

We have that as:

1\text{ + 4 = 5}

c) Midline:

midline\text{ = }\frac{max\text{ + min}}{2}\text{ = }\frac{6-2}{2}\text{ = }\frac{4}{2}\text{ = 2}
