Answer:
-5x + y = -1 or y = 5x - 1
Step-by-step explanation:
5x - y = 9
-5x - 5x
__________
-y = -5x + 9
__ ______
-1 -1
y = 5x - 9
__________________________________________________________
-6 = 5[-1] + b
-5
-1 = b
y = 5x - 1
If you want it in <em>Standard </em><em>Form</em>:
y = 5x - 1
-5x -5x
_________
-5x + y = -1 >> Line in <em>Standard</em><em> </em><em>Form</em>

Answer: Area=36
Step-by-step explanation:
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."
Step-by-step explanation:
45% of number = 180
=> 100% of number = 180 * (100/45) = 400.
Hence the number is 400.
