Answer:72
Step-by-step explanation: This is because of 18 in the first row *4 which is 72
The answer is x bc when you decreasing the interval f(x) it will equal (-2)
Answer:


And replacing we got:

And for this case we can use the first point to find the intercept like this:

And solving we got:

And then the line equation would be given by:

Step-by-step explanation:
For this case we have the following two points given:

And for this case we want an equation for a line with the two points given by:

Wher m is the slope and b the y intercept. We can find the slope with this formula:

And replacing we got:

And for this case we can use the first point to find the intercept like this:

And solving we got:

And then the line equation would be given by:
