Isolate the variable by dividing each side by factors that don't contain the variable.
x = - 6
Answer:
True
Step-by-step explanation:
It is true because the graph of
passes through the point 
x = 16
y = 4
Substitute
4 = 16 - 12
4 = 4
Therefore, the answer is true.
Answer:
The value of the test statistic is 
Step-by-step explanation:
The null hypothesis is:

The alternate hypotesis is:

Our test statistic is:

In which X is the sample mean,
is the value tested at the null hypothesis,
is the standard deviation(square roof of the variance) and n is the size of the sample.
In this problem, we have that:

So



The value of the test statistic is 
Answer:
3x plus 5 is definetely greater than -16 cause of the negative and 8 is bigger also then a negative
Step-by-step explanation:
The points (0, 3) and (4, -1) are on the graph of y = -x + 3.
I have a site that I use a lot that is perfect for problems like these. It's called Desmos.com. It's basically a free online graphing calculator that is super helpful for most problems relating to graphs.
