Answer: 4 / 11
Step-by-step explanation:
There are 4 vowels in total, 11 cards.
Answer:
Step-by-step explanation:
Step 1: Subtract -2x from both sides.
x2+x−7−−2x=−2x−−2x
x2+3x−7=0
For this equation: a=1, b=3, c=-7
1x2+3x+−7=0
Step 2: Use quadratic formula with a=1, b=3, c=-7.
x= −b±√b2−4ac / 2a
x= −(3)±√(3)2−4(1)(−7) / 2(1)
x= −3±√37 / 2
x= −3/2 + 1/2 √37 or x= −3/2 + −1/2 √37
Answer:
x= −3/2 + 1/2 √37 or x= −3/2 + −1/2 √37
Answer:
(0, 1/3)
Step-by-step explanation:
You find the y-intercept when the x value is 0, so plug in 0 for x and simplify
f(x) = -(2/9)(0) + 1/3
f(x) = 1/3
The y-intercept is at the point (0, 1/3)
Consider the given equation to be f(x) whose first derivative is positive for all real x. This implies f(x) is a strictly increasing function. Thus it has only 1 root.
