X/2 = 8
▶ ️2 = 8 × X. (transposing X to RHS )
▶️ 2 = 8X
▶ ️X = 8/2. (transposing 2 to RHS )
▶️ X = 4
hence the value of X is 4.
Answer:
The smallest xx-intercept is 
The largest xx-intercept is 
The yy-intercept is
.
Step-by-step explanation:
Given a quadratic function in the following format:

The x-values of the x-intercepts are
, given by the following formulas.



We have that:

This is not in the format above. I will multiply by (-1), so we have:

So, 



This means that
The smallest xx-intercept is 
The largest xx-intercept is 
The y-intercept is the value of f(x) when x = 0. So


The yy-intercept is
.
Answer:
-1/2
Step-by-step explanation:
cos(x+pi) = -cos(x), so the answer is -1/2.
Let's begin by listing out the information given to us:
There are four students: n = 4
Number of students to be selected: r = 2
To calculate the combination of 2 students to be chosen, we use:

Therefore, there 12 possible combinations from these
