Answer:
true.
Step-by-step explanation:
Answer:
See explanation below to use the vertex form to solve a quadratic equation.
Step-by-step explanation:
(x - h)^2 - k = 0, the vertex is (h, -k)
An example below, taking a quadratic equation and completing the square:
x^2 - 2x - 1 = 0
x^2 - 2x = 1
(-2/-2)^2 = 1, add 1 to both sides of the equation.
x^2 - 2x + 1 = 1 + 1
(x - 1)^2 = 2
(x - 1)^2 - 2 = 0
The vertex is (1, -2)
Answer:
x = -10
Step-by-step explanation:
First, determine the slope of the answer. The x-axis is a horizontal line, thus the new line must be vertical. All vertical lines are represented by the equation x = a number. That number represents the x-value of all the points the vertical line passes through.
So, since the line passes through (-10, -1), take the x-value of that point and put it into that equation. Thus, x = -10.
Answer:
b
Step-by-step explanation:
The expected outcome of spins based on the probability information is 60.
<h3>How to calculate the probability?</h3>
From the information, Joey decides to spin the wheel 60 times. Therefore, the expected outcome of spins is 60.
The thing that the booth owner can do to make the wheel more profitable for himself is to make winning probability less than that of losing.
Here, the booth owner do makes the wheel more profitable for himself as the winning is smaller.
