Yes because it is linear, also if you set up the proportion 2/4=1/2 they are equal.

Answer:
x = sqrt 2, y = 2
Step-by-step explanation:
45-45-90 triangles have a ratio of 1 : 1 : sqrt2
1. Plug in the 3 in all the x’s that are in the equation:
(3)2 + y2 = for x2 + y2
(3)2 - y2 = for x2 - y2
This would get you for both equations..
6 + y2 = for x2 + y2
6 - y2 = for x2 - y2
2. Now let’s plug in the value of y which is -4:
6 + (-4)2 = for x2 + y2
6 - (-4)2 = for x2 + y2
This would get you for both equations...
-2 = x2 + y2
14 = x2 - y2
Hope this helped, have an awesome day!
Answer:
y=-8
Step-by-step explanation:
Let's solve your equation step-by-step.
15y−4=12y−28
Step 1: Subtract 12y from both sides.
15y−4−12y=12y−28−12y
3y−4=−28
Step 2: Add 4 to both sides.
3y−4+4=−28+4
3y=−24
Step 3: Divide both sides by 3.
3y
3
=
−24
3
y=−8
