Answer:

y = 15x + 200

Step-by-step explanation:

It should be y = 150x + 200 because if you look at the first one, 300x is too big.

You can cross out the last two.

Then you can see the second one also doesn't work.

Cross that one out.

The first choice is the only one.

Answer:

The last choice.

Step-by-step explanation:

$\dfrac{k^2-k-2}{k^2-4k-5}=\dfrac{(k+1)(k-2)}{(k+1)(k-5)}=\dfrac{k-2}{k-5}$

The value of k must be restricted from being one that makes the original denominator zero. Hence k ≠ -1 or 5.

Answer:

P ≈ 100

Step-by-step explanation:

260 = P(1+0.054/365)^365(14)

260 = P(1.000147945)^5110

260= P(2.129621112)

P= 122.087444818

P ≈ 100
