You can tell if lines are perpendicular or not by seeing if meet in a right angle. A right angle is like a square, and the lines would have to be 90 degrees.
One example is when the two lines (horizontal and vertical) meet each other at the ends.
(You MUST make sure that they are directly horizontal and vertical. If not, they will either be acute or obtuse).
I hope this helped!
Answer:
-22d -102

Answer:
Step-by-step explanation:
For each game played the chance of winning is 0.05 and losing is 0.95.
If the student wins, they get $5 -$1 = $4, but they lose $1.
<u>Expected value is:</u>
It means you will make $0.75 per average game.
Answer:
y intercept (0, 4)
x intercept (4, 0)
I hope this is good enough:
$2,500 • 7.5% (or 0.075) = $187.50 (for one year).
For two years, the interested added onto the original price is $375 because $187.50 • 2 (years) = $375.
$2,500 + $375 = $2,875
The total of the cost of the surgery and the interest is $2,875.
Hope this helps! ❤️
