Answer:

see explanation

Step-by-step explanation:

The given formula is a recursive formula which allows a term in the sequence to be found using the previous term.

Given

$A_{n}$ = $A_{n-1}$ + 3 with A₁ = 2, then

A₂ = A₁ + 3 = 2 + 3 = 5

A₃ = A₂ + 3 = 5 + 3 = 8

A₄ = A₃ + 3 = 8 + 3 = 11

A₅ = A₄ + 3 = 11 + 3 = 14

The first 5 terms in the sequence are 2, 5, 8, 11, 14

What are the factors of expression (y-3)(x+7)

torisob [31]

That is easy!! :)
y=3 and x=-7

When you find the factors of something like this, you have to just get the letter alone.

For example: y-3. You have to first write it as y-3=0, then you add 3 from BOTH sides of the = so that you can make the -3 go away and y will be alone. So, it will look like this: y-3+3=0+3. Then, you solve it for y (which just means that you want y by itself on one side of the = ). So, -3+3=0, which means they disappear from that side; since 0+3=3, that's what that side turns into, so what you end up with is y=3

Same thing goes for the x+7 equation:
x+7=0
x+7-7=0-7
x=-7
