Two lines are perpendicular if their slopes are in a relation .
So we need to find slopes and if the above relation holds then we can claim the lines are perpendicular.
To find slopes, use slope formula
The first slope of a line passing through is
The second slope of a line passing through is
Now check if is true
This means the two lines <em>are</em> perpendicular.
Hope this helps.
Answer:
$779.1
Step-by-step explanation:
Original price = $980
<em>Michelle bought a computer that was 25% off the regular price of $980. </em>
Amount Michelle bought it = 75% of $980 = 0.75 * 980 = $735
<em>If a 6% sales tax was added to the cost of the computer,</em>
Sales tax = 6% of $735 = 0.06 * 735 = $44.1
<em>what was the total price Michelle paid for the computer?</em>
Total Price = Amount Michelle bought it + Sales Tax
Total Price = $735 + $44.1 = $779.1
