By using shadows, Megan wants to find the height of a flagpole. At a certain time of day, her shadow is 3.5 feet long and the flagpole’s shadow is 14 feet long. Her height is 5.5 feet. How tall is the flagpole?

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?

it would open into a square depending on the type of envelope i’m not sure about the second part

x=-7

step-by-step explanation:

x+3=-10

-10+3=-7

x=-7
