For this case we have:
We define the following variable
x : Speed of the car in South direction
By definition, we know that:
For the car in north direction:
For the car in south direction:
The distance between both cars, after 3 hours, is:
So, we have:
Clearing x;
Thus, the speed of the car in the south direction is
Answer:
Option B
The Original Number is 36 :)
explanation:
Step-by-step explanation:
Quadratic Formula:
√-1 is imaginary number i
Step 1: Define
y = -3x² + 4.5x - 20
a = -3
b = 4.5
c = -20
Step 2: Substitute and Evaluate
basically u have to beble gep
art
c $99,400
$195,00-$120,000=$75,000
$75,000+$5,000+$1,400=81,400
$81,400+$38,000-$20,000=$99,400
