Answer:
Step-by-step explanation:
(3-(-6)) / (6-3) = 9/3 = 3
The answer is 26 square units. You use the distance formula to calculate the side lengths then multiply length by width.
So, we know that a^2 + b^2 = c^2. Right? That is called the Pythagorean Theorem.
In this case. We can say that 39 is a, 40 is b, and x is c.
NOTE: It doesn't really matter whether 39 is a or b. a & b are just the two legs of the right triangle.
So, if we say that 39 is a, 40 is b, and x is c. We can plug it into the Pythagorean Theorem.
39^2 + 40^2 = x^2
I'll let you take it from there.

We know that
S. Harlow can bicycle at a rate of 18 miles per hour. To find out how many hours it will take him to bike <span>450 miles we need to use division.
450 </span>÷ 18 = 25
It will take him 25 hours.
Check your work.
18 x 25 = 450
We are correct.
Step-by-step explanation:
The domain of a graph is all of the possible x values, and the range is all possible y values.
7. The graph goes on for both the x and y values, so the domain is (-inf, inf) and the range is (-inf, inf).
8. In this case, the domain is also (-inf, inf), but the range is [-2, inf) as there are no y values less than -2.
9. The domain is [-2, 2], as the x values only range from -2 to 2. The range is [-3, 3] as the y values range from -3 to 3.
10. The domain is (-inf, inf) because all x values are possible. The range is [-1, 1], as there are no y values greater than 1 or less than -1.
