There are no solutions. These two equations never intersect
The content of the square root must be greater than or equal to zero. Determine the conditions on x that make this true.
As written, you require
.. x ≥ 0
If you intend
.. √(x -1) ∈ ℝ
Then
.. x -1 ≥ 0
Solve this inequality by adding 1.
.. x ≥ 1
Simplify the equation: -3 = 2 + 5v. Subtract 2 from each side to isolate v, this results in: -5 = 5v. Divide both sides by 5 to get the answer to v: -1 = v.
Answer:
9.275 inches or 9 11/40
Step-by-step explanation:
current depth = beginning depth - inches swam up + inches swam down
8 3/4 - 2 3/5 + 3 1/8
= 9 11/40
1) 2x + 3y = 12 -> 3y = -2x +12 -> y = -2/3x + 4
2) 4y - 7x = 16 -> 4y = 7x + 16 -> y = 7/4x + 4
