Diagram?... I dont know
Means, for every 1 input, there is 1 coresponding output
normally x is input and y is output in form (x,y)
so just look for the option(s) that has/have every first number repeat with only 1 2nd number
A. -7 repeats with 5 and -3, not a function
B. no repeats of first number (6,-8) and (-5,-8) are fine because first numbers don't repeat, das is funciton
C. no repeats, function
D. no repeats, function
answer is B,C,D
Answer:
The 3 positive integers of which the sum is equal to their product are, 1 , 2 and 3
1 + 2 + 3 = 6
So, when we add 1, 2 , and 3, we get six, now let's see on multiplying them,
1 * 2 * 3 = 6
Hence, the positive integers that have the same sum as their product are,
<em> 1 , 2 , and 3</em>

Answer is A.
step 1 , 16 was not multiplied by 9
should be
54x - 9y = 144
Answer: 39 years old
Step-by-step explanation:
First find Sarah's age.
It is said that their ages sum up to 50 and that Sarah's mother is 28 years older than Sarah.
Assume Sarah's age is x.
Sarah's mother's age would be: x + 28.
The expression would therefore be:
x + (x + 28) = 50
2x + 28 = 50
2x = 50 - 28
x = 22/2
x = 11
Sarah is 11 which means her mom is:
= 11 + 28
= 39 years old
