Answer:
C
Step-by-step explanation:
What makes a function is if each input or x-value has EXACTLY one output or y-value.
a. is wrong because the x value 1, has both an output of 1 and 4
b. is wrong because -1 is repeated 4 times with all different outputs
c. is correct because each input has exactly one output. None of the x values repeat itself
d. is wrong because -1 has 2 outputs.
so this is what makes a function and what doesn't. Hope this helps!

Answer:
2 pieces.
Step-by-step explanation:
To identify how many pieces he can split with 8/10 of a candy bar, divide 8/10 by 1/3.
<u>Divide 8/10 by 1/3:</u>

<u>Find the Ricipricol, then flip the sign:</u>

<u>Multiply:</u>
<u />
2.4 represents how many pieces of chocolate he can make with 8/10 of a candy bar.
However, 2.4 pieces can't be made, therefore he can only make 2 <u>full</u> pieces.
Answer:
<h3>⇒ A. 2 should be distributed as 2y + 12, y = 6</h3>
Step-by-step explanation:
Here are the steps to solve this equation:
<u>Given:</u>
First step: 2(y+6)-4y
Use the distributive property.
<u>Distributive property:</u>
<h3>
⇒ A(B+C)=AB+AC</h3>
2(y+6)
2*y=2y
2*6=12
2y+12
Isolate the term of y from one side of the equations.
2y+12=4y
Subtract by 12 from both sides.
2y+12-12=4y-12
Solve.
2y=4y-12
Then, you subtract by 4y from both sides.
2y-4y=4y-12-4y
Solve.
2y-4y=-2y
-2y=-12
Divide by -2 from both sides.

Solve.
Divide the numbers from left to right.
<u>Solutions:</u>
-12/-2=6

- <u>Therefore, the correct answer is A. "2 should be distributed as 2y+12, y=6".</u>
I hope this helps. Let me know if you have any questions.
Answer:
8x-8
Step-by-step explanation:
if Lana is X year
then that makes Yan 3X-4
