Answer:
<u>D) x² - y = 10x + 25 + y</u>
Step-by-step explanation:
A relation only becomes a function if each x-value only has a single y-value as the answer.
<u>Evaluating</u>
- A and B cannot be the answers as each value will get 2 answers
- C will also not be the answer as y² means at least 2 answers will be given
- <u>D</u> is the best option as each inputted x-value will get an answer of a single y-value

- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
6x - y = -14
-2x + y = 6
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Elimination</em>
- Combine 2 equations: 4x = -8
- Divide 4 on both sides: x = -2
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define equation: -2x + y = 6
- Substitute in <em>x</em>: -2(-2) + y = 6
- Multiply: 4 + y = 6
- Isolate <em>y</em>: y = 2
Answer:
10
Step-by-step explanation:
boxes= 2.5× 4.5× 6.2= 69.75
tray= 2.5× 9× 31= 697.5
697.5÷69.75= 10
