Answer:
The point (0, 25) is not a solution, but the point (-4, 10) is a solution.
Step-by-step explanation:
You can graph the inequality and check. The first point (0, 25) is on the boundary line, but that line is NOT part of the solution set. The second point (-4, 10) is well inside the solution space.
(0, 25) is not a solution
(-4, 10) is a solution
_____
You can put the values into the inequality and see if a true statement results.
-10(0) +(25) > 25 . . . . False
-10(-4) +(10) > 25 . . . . true
The first point is NOT a solution; the second point IS a solution.
Each value in the 'x' column (on the left) is unique. There are no repeated x values. This means we do have a function.
Put another way, each x value leads to exactly one y value. This is another way to see that we have a function. A function input must have one output or else it would lead to confusion or ambiguity. For example, let's say you wanted to convert from celsius to fahrenheit. You would use the conversion function F = (9/5)C+32. The idea is whatever celsius C value you plug in, you should get ONE and only one fahrenheit value. Otherwise, it would be impossible to know which fahrenheit temperature to go with.
Yet another way is to graph each (x,y) point and notice it is impossible to draw a single vertical line through more than one point mentioned in the table. This graph passes the vertical line test to further confirm that we do have a function.

Answer: Yes, because every x-value corresponds to exactly one y-value
In other words, the answer is choice B

Ella is baking cookies to put in packages for a fundraiser. Ella has made 86 chocolate chip cookies and 42 sugar cookies.
Ella wants to create identical packages of cookies to sell, and she must use all of the cookies.
What is the greatest number of identical packages that Ella can make?
Multiply the denominators to make it one fraction.
Now for the numerator, you multiply the numerator of the the 1st fraction with the second fractions denominator. Then Multiply the 1st fractions denominator with the 2nd fractions numerator. Now with those two numbers you Subtract it. Whatever number you get is the numerator. So there is the fraction. You would just simplify it. (IF you want to add fractions instead of subtracting the numerators, you add the numerators. Like instead of 68-12 you would do 68+12
