Answer:
x
Step-by-step explanation:
Start with hours worked 6 x $9 = 54
Then commission $700 x 0.12 (12% converted to a decimal) = $84
Add up 54 + 84 = $138 total income
So answers are A, the first C (you make $84 in commission), and the last one, you make $138 in total.
Yes, this would be a function.
Using ordered pairs to represent this, we would have (jersey #, points). A relation is a function if no element of the domain matches more than one element of the range; in our case, the domain is the jersey number and the range is the number of points.
The jersey number will not match two numbers of points throughout the season; a player will only have one total number of points throughout the season. Therefore no element of the domain matches more than one element of the range, and this is a function.
Answer:
x = ±3
Step-by-step explanation:
Step 1: Write equation
7x² = 63
Step 2: Solve for <em>x</em>
- Divide both sides by 7: x² = 9
- Square root both sides: x = ±3
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
7(3)² = 63
7(9) = 63
63 = 63
7(-3)² = 63
7(9) = 63
63 = 63
