Think of the 13-ft length of the ladder as the hypotenuse of a right triangle. Represent the horiz. distance from foot of ladder to base of tree by x, or 5 ft.
Represent the vert. dist. from base of tree to top of ladder by y, which is unknown.
Then (13 ft)^2 = (5 ft)^2 + y^2, or
169 ft^2 = 25 ft^2 + y^2. This simplifies to y^2 = 144. Thus y = + 12 feeet.
Note: Please pay attention to your spelling: "lader i up agenst a tree" should be "the top of a 13-ft ladder is placed against a tree."

Answer:
First one: function and linear
Second one: function and non-linear
Third one: not a function and linear
Step-by-step explanation:
• The first one is set in the linear function formula y=mx+b, so it is a linear function.
• The second one is a non-linear because functions with exponents have different shapes and can intersect more than once unline linear functions.
• The third one isn't a function but it is linear because it isn't set equal to a variable and it would become a linear if you simply it to isolate a variable.
I hope this helps!!!
