Answer:

The screenshot shows the correct answers; 5x + 5y = 25 is linear.

For a equation to be linear:

The equation should not have square root, cube root, etc.
The value of x is not greater than one. X should not have an exponent.
X is not in a denominator of a fraction.
"xy" should not be in the equation.

The formula for circumference is C=2*pi*radius. Therefore your setup would be C=2*pi*3.1. When you actually work this out you get 19.5 after rounding.

How would you describe the graph of the function in interval 2? Select all that apply.

The graph of the function is missing and so i have attached it alongside the options.

Answer:

B & C are correct.

Step-by-step explanation:

From the attached graph, we can see that at interval 2, the line is falling down and not rising.

This means that the function is decreasing because y is decreasing while x is increasing.

Also, when both x and y are increasing, the slope is positive but when one is increasing and the other is decreasing like we have here, it means the slope is negative.

Thus, the function is decreasing and the slope is negative.
