X+y = -2 is the same as y = -x-2 when you subtract x from both sides
x+y = -2 is the same as 2x+2y = -4 when you multiply both sides by 2
So A, B, and C are the same equation just in a different form.
Answer: Choice D) any of the above
Just plug in the numbers:
4: 16 + 24 = 40 YES
5 = 25 + 40 ≠ 40 NO
8: 64 + 48 ≠ 40 NO
10: 100 + 60 ≠ 40 NO
So A. is the correct answer. Just to be sure:
-10: 100 + ( - 60) = 40
Your answer is A. Hope that helps! :)
Answer:
25 mini loaves
Step-by-step explanation:
Using the first set you can divide and tell that 1 cup of flour is equal to 2.5 mini loaves, applying that to the other set you can inquire that it's true. So therefore what you need to do is multiply 2.5 times the amount of flour you are using.
10 cups = 25 mini loaves
Answer:
B
Step-by-step explanation:
To be a function every input must have exactly one output. There are two input values with 2, therefore this makes it not a function.
