Answer:
x=19
Step-by-step explanation:
To find this we need to find the simplest form of y and x
Chart:
----------------------------------------------------------------------------------------------------------------Y | 45 |
X | 15 |
----------------------------------------------------------------------------------------------------------------
To find the simplest form divide both sides with their gcf which is right now 15 so divide by 15: For y 15 divided by 45 is 3, for x 15 divided by 15 is one so the graph looks like this:
----------------------------------------------------------------------------------------------------------------Y | 45 | 3 |
X | 15 | 1 |
----------------------------------------------------------------------------------------------------------------
So now we know this fact we can just divide 57 by 3
(We need to divide it to see how many times does it take for 3 to get to 57 and we can use that number to multiply it with 1 and only one since when y is 3 x is 1.)
57 divided by 3 is 19
So we multiply 19 with 1 which is 19
So x is 19
Graph:
----------------------------------------------------------------------------------------------------------------Y | 45 | 3 | 57 |
X | 15 | 1 | 19 |
----------------------------------------------------------------------------------------------------------------
Hope this helps!
Answer:
The value of x is reduced to one third when the value of y is tripled.
Step-by-step explanation:
Here, y varies inversely with x.
⇒
Here, k = Constant of Proportionality.
⇒ k = x y .......... (1)
Now, given y' = 3 y
to find the value of x'
Putting the value in
or, k = 3 y x '.......... (2)
From above statement (1) and (2)
⇒ xy = 3yx'
or, x ' = x/3
Hence, the value of x is reduced to one - third when the value of y is tripled.
Answer:
x=y[base side of isosceles triangle]
x²+y²=19²
x=√{19²/2)}
x=13.44
y=13.44
