- Coordinates (x, y)
- Coefficients
- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
-5y + 8x = -18
5y + 2x = 58
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Elimination</em>
- Combine 2 equations: 10x = 40
- [Division Property of Equality] Divide 10 on both sides: x = 4
<u>Step 3: Solve for </u><em><u>y</u></em>
- Substitute in <em>x</em> [Original equation]: -5y + 8(4) = -18
- Multiply: -5y + 32 = -18
- [Subtraction Property of Equality] Subtract 32 on both sides: -5y = -50
- [Division Property of Equality] Divide -5 on both sides: y = 10
Answer: 6√7
Step-by-step explanation:
Geometric Mean: Multiply the 2 numbers and take the square root.
6 · 42 = 252
Now take the square root:
√252
Simplify the radical (if needed):
6√7
Your geometric mean is 6√7.

Answer:
F=70.7
Step-by-step explanation:
This is a simple substitution problem.
- The formula to change Fahrenheit to Celsius is
. - They give you C, so substitute it into the problem, which would give you
. - Simplify the right side of the equation by multiplying
by 21.5. - Now, add 32 to 38.7, which should have been your answer to the previous step.
- You should now have F= 70.7 as your answer.
