The answer to #2?? I already have the graph but I still need the answer

Sidana [21]

If we have

y = 6x + 1 and x - y = 11, we can take advantage of y - y = 0 as follows:
Subtract x from both sides of the 2nd equation:
-y = 11 - x

Now combine

y = 6x + 1
-y = 11 - x
--------------
0 = 5x + 12. Solving for x, x = -12/5. Using the equation above, find y:
-y = 11 - x
= 11 - (-12/5)
= 55/5 + 12/5 = 67/5

Then the solution is (-12.5, 67/5).

Show that 3 · 4^n + 51 is divisible by 3 and 9 for all positive integers n.

-BARSIC- [3]

Answer:

Step-by-step explanation:

Hello, please consider the following.

$3\cdot 4^n+51=3\cdot 4^n+3\cdot 17=3(4^n+17)$

So this is divisible by 3.

Now, to prove that this is divisible by 9 = 3*3 we need to prove that

$4^n+17$ is divisible by 3. We will prove it by induction.

Step 1 - for n = 1

4+17=21= 3*7 this is true

Step 2 - we assume this is true for k so $4^k+17$ is divisible by 3

and we check what happens for k+1

$4^{k+1}+17=4\cdot 4^k+17=3\cdot 4^k + 4^k+17$

$3\cdot 4^k$ is divisible by 3 and

$4^k+17$ is divisible by 3, by induction hypothesis

So, the sum is divisible by 3.

Step 3 - Conclusion

We just prove that $4^n+17$ is divisible by 3 for all positive integers n.

the total charge for a yearly internet movie rental membership is $231.A registration fee of $15 is paid up front and the rest i

Flura [38]

New members pay a fee of $18 per month.

Step-by-step explanation:

Given,

Yearly movie rental cost = $231

Registration fee = $15

1 year = 12 months

Let,

x be the fee per month.

12x+15=231

$12x=231-15\\12x=216$

Dividing both sides by 12

$\frac{12x}{12}=\frac{216}{12}\\x=18$

New members pay a fee of $18 per month.
