Answer:
$22.68
Step-by-step explanation:
Meal Price =$18
Sales tax =6%
Tip = 20%
Total Price of the Meal =$18 + (6% of 18)+ (20% of 18)
=$18 + (0.06 X 18)+ (0.2 X 18)
=18+1.08+3.6
=$22.68
The total price of Alyssa's meal is $22.68.
Answer:
see below
Step-by-step explanation:
First determine how much is subtracted from the account
12.57+24.95+36.86 =74.38
They charge .15 per check=3*.15 = .45
Subtract the amounts of the checks and the check fees
139.50-74.38-.45 =64.67
Answer:
About 7:45
Step-by-step explanation:
7:40 OR 7:45 because sometimes the traffic light takes a while but 7:45 is best.
Given a quadratic equation 
, we define the discriminant as
The number of real solutions of the equation depend on the sign of 
:
- If
the equation has two solutions - If
the equation has one double solution - If
the equation has no real solutions
In this case, we have
And so this equation has no real solutions.
In general, √(y²) = |y|, since y can be positive or negative and y² would have the same value either way.
So,
1) if y > 0, then |y| = y, and
-15√(y²) = -15 |y| = -15y
2) if y < 0, then |y| = -y, and
-√(16y²) = -|4y| = -|4| |y| = -4 (-y) = 4y
