You add 2x and 7x to get 9x
so the answer is 9x+5y
3/10=4/x
3x=10(4)
3x=40
x=13.33
Answer:
-0.25, -0.15, -0.6
Step-by-step explanation:
- 1/4= -0.25.
Bigger number with negative = smaller number
Answer:
Symmetric point: x = -1; (-1, 5)
Minimum of f: None; approaches -∞.
Maximum of f: y = 5.
Is f(x) a one-to-one: No, it fails the horizontal line test and is not injective.
Increasing from: -∞ to -1; (-∞, -1)
Decreasing from: -1 to ∞. (-1, ∞)
