Answer:

Step-by-step explanation:
We have been given the function

From the rational zeros theorem, we have

From the given function,
Leading coefficient = 2
Factors of 2 are 1,2
Constant term = 18
Factors of constant term = 1, 2, 3, 6, 9, 18
Hence, we have

Answer: the number of favorable outcomes
Step-by-step explanation:
It says it on Apex
Answer:
D
Step-by-step explanation:
When you have two opposite numbers on a numberline, that is, a digit that has a negative value and the same digit having a positive value, when you add them together, we would have 0.
i.e. -a + b = 0
In the above options given, the numberline that shows this particular case is the numberline in option D.
In option D numberline, the sum of -1 and +1 equals zero.

Step-by-step explanation:
Let's rewrite the given equation such that only y is on the left side and everything else on the right side:

Simplifying this by dividing by 6, we get

This line has a slope of -1/2, which means that a line perpendicular to this has a slope of 2 (i.e., negative reciprocal). So we can write its equation as

This is the slope-intercept form of the equation of the line perpendicular to our given line. To complete this form, we need to find the value of b. Since this line passes through (1, -7), put these numbers into our equation to get

Therefore, the slope-intercept form of the equation can be written as
