Answer:
Below.
Step-by-step explanation:
The center is at (8, 4) and the radius = √11.
√11 = 3.317 to the nearest thousandth.
50 times 12 equals 600 minus 520 equals 80 bars left over.
Choice D is true. It is just another way to write the given function.
To confirm choices A through C, replace x as follows and do the math:
For A, let x = -3. Does it really yield -11?
For B, let x = 0. Does it really yield 5?
For C, let x = 1/2. Does it really yield 4?
Take it from here.
Let the two numbers be x and y, then
xy = 99 . . . (1)
x + y = -34 . . . (2)
From (2), x = -34 - y . . . (3)
Putting (3) into (1), gives
(-34 - y)y = 99
-34y - y^2 = 99
y^2 + 34y + 99 = 0
Therefore, the two numbers are
and
