Hey and help me help me help plz

17

Step-by-step explanation:

First you subtract 13-9 to find the distance between the 2 numbers. That gets you 4 but if the numbers are 2 spaces away from one another then that means that the number line increases by 2. Then you add 4 to 13 and that’s how you get 17.

easy its decreasing

step-by-step explanation:

because its top point is at the to of the graph on the left side (atleast from the veiw i see it) now if that top point wast in the lower part of the graph it would be increasing hope this have a nice day

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
