Answers:
choice A) y = 0x
choice D) y = 0/x
========================================================
Explanation:
Choice A is the same as y = 0 because 0x turns into 0. Multiplying 0 with any number always leads to 0.
Similarly, choice D is the same as y = 0 as well. Dividing 0 over any nonzero value leads to 0. Note the key term "nonzero" here. We cannot have 0 in the denominator. So x = 0 is not allowed for choice D.
So for any nonzero x, we have 0x and 0/x result in the same thing.

Extra info:
Choice B can be ruled out because something like x = 2 leads to y = 2.
Choice C is ruled out because we can never have 0 in the denominator.
Answer:
The answer is
<h2>x² + y² + 6x - 16y - 71 =0</h2>
Step-by-step explanation:
The equation of a circle is given by
<h3>( x - a)² + ( y - b)² = r²</h3>
where ( a , b) is the center of the circle and
r is the radius
From the question the center is
P (-3, 8) and radius = 12
Substitute the values into the above formula and solve
That's
( x + 3)² + ( y - 8) = 12²
<u>Expand the terms</u>
That's
x² + 6x + 9 + y² - 16y + 64 = 144
<u>Arrange the terms</u>
x² + y² + 6x - 16y + 9 + 64 - 144 = 0
We have the final answer as
<h3>x² + y² + 6x - 16y - 71 =0</h3>

The area of the largest circular fire pit is 452 square inches.
Explanation:
Given that at a campground, a rectangular fire pit is 3 feet by 2 feet
The radius is given by 1 feet.
<u>Area:</u>
The area of the largest circular fire is given by
Substituting the values in the formula, we get,
Thus, the area of the largest circular fire is 3.14 square feet.
<u>To convert feet to inches:</u>
The feet can be converted into inches by multiplying by 12.
Thus, we have,
Hence, we have,
Simplifying,we get,
Rounding off to the nearest square inch.
Thus, we have,
Thus, the area of the largest circular fire pit is 452 square inches.
Answer:
14,10
Step-by-step explanation:
8=(x+2)/2
16=x+2
x=14
4=(y-2)/2
8=y-2
y=10
First we solve system to see what it indicates.
multiply first equation by 3 and subtract it from second.
it will become
3x + 3y = 72
after subtracting from second we get:
2y = 28
y = 14
x = 24 - 14 = 10
We can conclude that there are more 5 points question. there are 10 three point questions and 14 five point questions.
