Then, it would be: 1/2 (n+2) - 2/5 n = 5
So, OPTION B is your answer.....
Answer:
radius = 10
(x-5)² + (y-11)² = 100
Step-by-step explanation:
The circumference is given, we get r = 20π/2π = 10
∴Equation of circle is (x-5)² + (y-11)² = 100
Answer: I can help you to solve by graphing the second one, the 2 answers are 1. Slope: 1/3, x-intercept: (–6, 0), and y-intercept: (0, 2). And 2. X-intercept: (–3, –2, –5/6, 0, 1) and Y-intercept: (–16, –6, –23/12, –4, –12)
Step-by-step explanation:
Answer:

Step-by-step explanation:
Answer:
Option B , C and E are correct

(y+25)(y-30)=0
Step-by-step explanation:
Given : Area of rectangular room is 750 square feet.
Width of the room is 5 feet less than the length of the room.
Let y be the length of the room
then,
As per the given condition
width of the room is: y-5
Area of rectangle is multiply the length by its width.
Area of rectangle = 
Substitute the given values in above formula we get;
......[1]
or we can write this as;
750 -y(y-5)=0
[1] ⇒
or
or


(y+25)(y-30)=0
Therefore, the equation which can be used to solve for y are;
,
and (y+25)(y-30)=0
