Since x=x, this is an isosceles right triangle. By the Pythagorean Theorem:
h^2=a^2+b^2 (the hypotenuse squared is equal to the sum of the squared sides)
5^2=x^2+x^2
25=2x^2
2x^2=25
x^2=25/2
x=√(25/2)
x=5/√2 now if we rationalize the denominator...
x=(5√2)/(√2√2)
x=(5√2)/2
It is in y intercept form
y = mx + b
where b is the y intercept
y = 3/4 x + 2
so b = 2
therefore the y intercept is 2
Try -×=4??? i just started to learn how to do variable expressions correctly bc i just transfered to an high accelerating school, but if I'm wrong w the answer im very sorry, as i am just now learning.

Answer:
Step-by-step explanation:
We are given that Twice the difference of a number and 2 is equal to three times the sum of the number and 4. And we have to tell the number.
Let the number be x
Its difference from 2 = x-2
Twice the difference =2(x-2)
Sum of number and 4 = x+4
Three times of the sum : 3(x+4)
Hence 2(x+2)=3(x+4)
2x+2×2=3x+3×4
2x+4=3x+12
Subtracting 12 and 2x from both sides.
4-12=3x-2x
-8=x
Hence the number is -8
