Writing an Equation to Represent a Real-World Problem
Caitlin is designing a railing for a set of stairs. The railing Which function can represent the height, y, of the
will begin at a height of 36 inches and follow the slant of railing in inches according to the horizontal distance in
the stairs, which decreases 9 inches for every 12 inches, x, from the top of the stairs?
horizontal inches
y=-3x + 36
4.
O y=-3x + 36
36 in
© y = x + 36
y = 3x + 36

the answer is: the length is 5/6 yards.

give me a or a 5 star rating if this is correct!

step-by-step explanation:

the argument of alfred t. mahan, henry cabot lodge, and albert j. beveridge was the economically and mass production the the americans could not consume themselves. this led expansion to sell to other foreign nations for profits.

step-by-step explanation:

this is my explanation

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
