r/v + a = 5
subtract a from both sides
r/v = 5-a
multiply by v on both sides
r = v*(5-a)
Answer:
A) 1
Step-by-step explanation:
To solve, just plug in the numbers to the equation for x until both sides are equal to each other.
Plug in 1:
2(1 + x) = x + 3
Let x = 1:
2(1 + 1) = 1 + 3
Solve. Remember to follow PEMDAS. First, add parenthesis, then multiply. On the other side, add:
2(1 + 1) = 1 + 3
2(2) = 4
4 = 4 (True)
A) 1 is your answer.

5 - 3x = -19
-3x = -24
Divide by -3
Solution: x = 8
These intervals are measured by the x-values. Additionally, intervals of increase and decrease are always express with parentheses in interval notation. Therefore, the decreasing interval is (-2, 0)U(1, 3) and the increasing interval is (0, 1).
Hope this helps!
I don't think two points is enough to determine a unique ellipse. In fact,
I'm sure of that. If you only have two point, then an infinite number of different
ellipses can be drawn through them. I know it takes three points to determine
a circle, and I'm sure you need at least that many for an ellipse.
