Answer:

A prime number is a number where no other number other than 1 can be divided by it. for example, 11 is a prime number because you can only do 11/1. You can't divide any number from 11 except 1 so it is a prime number

Hope this helps!

Answer:

7) First Circle

8)Also First Circle

Step-by-step explanation:

For the first one simplify the bottom expression to get (x-3)(x+7), then cancel out the numerator and x+7 to get 1/x-3. The restrictions are when you solve for x-3 and x+7

The second one is the same thing but this time we simplify the numerator to get (x+2)(x-5). Then, cancel out both x+2. Then you get x-5 as the answer and the restriction is -2 because x+2 is the denominator.

Hope this helps!

Hello,

The equation is written in point-slope form, and the formula is as follows: $y-y_{1} = m(x - x_{1})$ .

$x_{1}$ and $y_{1}$ are representing points on the graph.
$y_{1} = 5$ , and $x_{1} = 7$ .

So therefore, the final answer is B, (7, 5).
