Answer:
In this graph, the y-intercept of the line is -2, if the coordinates are needed, its (0,-2). The equation of the line is y= x-2 ( slope intercept form ).
Step-by-step explanation: I am not sure how to use the multiplication system below to write the equation, so sorry I couldn't help!
x = 9
Since M is the midpoint of XY:
XM = MY
XM = 2x + 11
MY = 5x - 16
2x + 11 = 5x - 16
5x - 2x = 11 + 16
3x = 27
x = 27/3
x = 8

Answer:
39 feet
Step-by-step explanation:
From the question;
let length of ladder =x feet
height of ladder will be=x-3 feet
ground distance of ladder bottom to building=15 feet
Applying Pythagorean relation
a²+b²=c²
where a=15 feet b=x-3 feet and c=x feet thus
x²-15²=(x-3)²
x²-225=x²-6x+9
collect like term
x²-x²-225-9=-6x
-234= -6x
x= 39 feet length of ladder
distance from ground to top of ladder= 39-3=36 feet
