Answer:

Step-by-step explanation:
In writing equations for circles with the center and radius given we follow the formula
.
The value of h and k are the center values of (0,0).
So we have:
h = 0
k = 0
r = 4
Now let's plug these values into our formula.



Answer:
The zeros of the function are x=-7 and x=2
Step-by-step explanation:
we have

we know that
The zeros or roots of the function are the values of x when the value of the function is equal to zero (also is called the x-intercepts)
so
For A(x)=0

Remember that
The <u><em>Zero Product Property</em></u> states that
if ab = 0, then either a = 0 or b = 0, or both a and b are 0
so
Let
----> 
----> 
therefore
The zeros of the function are x=-7 and x=2
Answer:
A + C
Step-by-step explanation:
n = how much the guitar costs.
You know that you spent $45 on the lesson, and the cost of the lesson plus the cost of the guitar equals 325.
280 comes from 325, the cost of the guitar and the lesson, plus the cost of the lesson.
hope this helped! :)
