K = -48
1. subtract 5 from both sides
-4 = k/12
2. multiply 12 from both sides to get k alone
-48 = k
Answer:
y = -5/4x + 7 1/4
Step-by-step explanation:
The difference in y (10) over the difference in x (8)
Answer:
See below
Step-by-step explanation:
<u>Given function</u>
<u>We can find its factors:</u>
- x³ + 3x² - 7x - 21 =
- x²(x + 3) - 7(x + 3) =
- (x² - 7)(x + 3)
We can conclude that the given polynomial function is fully divisible by (x + 3) and the quotient is (x² - 7)
Also one of zeros of the function is -3
Answer:

Step-by-step explanation:
It is given that, the radius of a circle is 8 inches and we are to find the circumference of the circle.

To find the circumference of the circle we must know this formula first :

Where
- r is the radius of the circle.
- We'll take the value of π as 3.14
Now substituting the values in the formula :



Therefore,
- The circumference of the circle is 50.24 inches
