The correct answer is A. y = 2x +1

Explanation:

An equation is a statement that shows equality. In this context, the equation should lead to two equal numbers even if the values of y and x change. In this context, the correct equation is y= 2X + 1 because this is the only one, in which, the value of Y is always equivalent to 2x + 1. To prove this, let's replace y and x for the values of the table.

First column

5 = 2 · 2 + 1

5 = 4 + 1

5 = 5

Second Column

9 = 2 · 4 + 1

9 = 8 + 1

9 = 9

Third column

13 = 6 · 2 + 1

13 = 12 + 1

13 = 13

Fourth column

17 = 8 · 2 + 1

17 = 16 + 1

17 = 17

A^2 +a-6. You use the method of foiling where you multiply the first two terms, the the outside terms, the inside terms, then the last terms. You would do a•a, then a•-2 the a•3 then 3•-2. You would get a^2 -2a +3a -6. Then combine like terms to get your answer.

1. Kim's age is twice that of her sister. When you add Kim's age to her sister's age, you get 24. How old is each

Andre45 [30]

Answer:

a) Let Kim's age be k, then Kim's sister's age is k/2

k+ $\frac{k}{2}$ =24

b) k+ $\frac{k}{2}$ =24

1 $\frac{1}{2}$ k=24

k=16

$\frac{k}{2}$ =8

Kim's age is 16 while her sister's age is 8.
