Answer:
A product of a number and 12 is increased by 23
Answer:
y= x + 85
Explanation:
If you plug in any of the x values you will get the y value
Circumference of a circle is simply C = πd, d = diameter.
now, we know the diameter is 80, so C = π80, or just 80π.
Add 121/4 to each side:
x²+11x+121/4 < 121/4-8
x²+11x+121/4 < 89/4
(x+11/2)² < √89/2 ⇒ -√89/2 < x+11/2 < √89/2
-11/2-√89/2 < x < -11/2+√89/2
Just type it into a calculator. (since there are three zeroes in 1000 just move the decimal point three times/spots to the left)
61.4/1000 = 0.0614
