Answer:
Yes, he is correct
Step-by-step explanation:
25% of 20 is 5 (0.25*20)
100% of 20 is 20
if you take 125% of 20, you'll end up with 25
Answer:
x = -18
Step-by-step explanation:
x - (-5)= - 23
you would do the opposite of -5 which is positive 5 and you would add 5 to the negative 5 to cancel out that -5 and add 5 to the -23 which gives you -18 so x = -18
Hope this helps!

7 weight exactly the same, therefore the 8th golf ball doesnt weigh the same as the 7. so the 8th ball is slightly lighter
Answer:
I think it is D. Because x=x and there's infinite possibilities.
Answer: Choice B
{(0,0), (1,2), (2,4), (3,4)}
===============================================
Explanation:
A function is only possible if each x input leads to exactly one y output. For choice A, we have x = 1 lead to y = 3 and y = 5 at the same time, which is what the points (1,3) and (1,5) are saying. Therefore, choice A is not a function.
Choice C is also ruled out because x = 2 repeats itself as well. In this case, (2,3) and (2,4) means that the input x = 2 leads to the two outputs y = 3 and y = 4.
Choice D can be eliminated also for two reasons: x = 0 shows up twice, so does x = 2.
Only choice B has each x value listed one time only. So that means each input leads to exactly one output.
If you graph choice A, C or D, you'll find they fail the vertical line test. The vertical line test is where you test if you can draw a vertical line through more than one point on the graph. If you can draw a vertical line through more than one point on the graph, then the relation fails to be a function.
