Step-by-step explanation:
If in any set, you can find 2 or more points that lie on the same vertical,
then it is NOT a function, that is, the same value of x yields 2 or more different
values of y, you don't have a function.
e.g. D is definitely not a function. You have (-2,4) and (-2,-4) , the same x of -2 giving you a y value of 4 and -4.
Answer:
The answer is the second one , 0=5 , no solutions .

Answer:
see below
a = 0.66...
b = 0.73
c = 7/8
Step-by-step explanation:
The first two numbers, 0.73 and 0.667, are near the point that is halfway between 0.6 and 0.8. That halfway point is 0.7. The value 0.667 will be below (left) of the halfway point, so is point <em>a</em>. The value 0.73 will be above (right) of the halfway point, so is point <em>b</em>. The remaining value, 7/8, must be point <em>c</em>.
__
You may know that 7/8 = 0.875, so is nearly halfway between 0.8 and 1.
_____
The attached graph has the points color-coded.
_____
Of course you know that the overline in 
indicates that digit repeats indefinitely. The value 0.667 is the number rounded to 3 decimal places.
Answer:
<h3>Circle</h3>
Solve for area
A=π r^2
r =Radius
<h2>You about this first: </h2>
The circumference of a circle is its perimeter or distance around it. It is denoted by C in math formulas and has units of distance, such as millimeters (mm), centimeters (cm), meters (m), or inches (in). It is related to the radius, diameter, and pi using the following equations: C = πd. C = 2πr.
