Write the following in slope-intercept form
12x + 10y = 100

slope-intercept form: y = mx + b

we know what format we need to change the equation to.

subtract 12x to each side to get 10y alone.

12x - 12x + 10y = 100 - 12x

10y = -12x + 100

divide 10 to both sides to get y alone.

10/10y = -12/10x + 100/10

y = -6/5x + 10

y = -6/5x + 10 is your answer. i hope this helpes! let me know if i got something wrong that i need to fix.

.

step-by-step explanation:

.

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.
