<em>- 5Y / 2 = 15</em>
<em>multiply both sides by 2, we get</em>
<em>- 5y = 30</em>
<em>Divide both sides by -5, we get</em>
<em>y = - 6 Answer</em>
Answer:
A
Step-by-step explanation:
Don't really want you to die ^^
d = total earnings so it's the dependent/y variable
h = hours so it's the independent/x variable
9.25 = earnings per hour or slope
b = 0 since Chakan starts off with $0
Using y = mx + b...
d = 9.25h + 0 or d = 9.25h
1. Joe- 2+b (or 2+1b)
Micheal- 2b
2. Joe- 2+10=12
Micheal- 2x10=20
3. one distributes and the other just adds regularly.
To solve this problem you must apply the proccedure shown below:
1. You have that the equation of the ellipse is the following:
(x²/400)+(y²/256)=1
2. You have that:
((x-0)²/400)+((y-0)²/256)=1
3. Then, the center is:
(0,0)
4. The vertices are:
a²=400
a=√400
a=20
(-20,0)
(20,0)
b²=256
b=√256
b=16
(0,-16)
(0,16)
5. The focci is:
a²–c²=b²
√(400-256)=c
c=12
(-12,0)
(12,0)
