The slope of the line = 1/2
Let them be X and Y..
now...
yx=100 ....
y=100/y ...
now...
x+y= s....where s is their sum...
but y=100/x
now....x+100/x=s..
by differentiating both sides with respect to x..
1-100/x^2=ds/dx
but ds/dx=0..
100=x^2 ..
x=10..
so y=10
For this type of problem the way to do it is..
1) add the inside of the triangle, in this case it is --> 132 + (2×+4) and then you set it equal to the number that's outside the triangle which is 112
2) and then you solve .... 132+4=136
3) your equation should look like ---> 2×+136=112
4) you subtract 136 from both sides
5) you get 2×= -24
6) divide 2 from both sides.. and you get ×=-12
that's if they are asking for the value of X
if they want to go further... you plug in the value of x in which we found was -12 into the angle above... I hope I helped.
Answer: The value of y is 
.
Explanation:
It is given that the graph of a proportional relationship passes through (12, 16)
and (1, y).
The graph of a proportional relationship means the x and y coordinates are in a proportion k. The equation of the graph is in the form of y=kx. Where k is the proportion factor.
It is given that the graph passing through (12,16).
So the equation of the line is,
put x=1.
Therefore, the value of y is .
