Equations for X and Y Needed: I get how to solve X and Y equations such as- "Solve for X," or ,"Solve for Y." I just need to make sure I don't forget HOW to do it. SO if you can, please write the equation in the first comment, and the answer to it in the 2nd one. Thanks for reading this :)

Step-by-step explanation:

x+2y=4

2x+y=5

x+y=1

3x-2y=4

-x-4=16

5x-3y=-11

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

x^6

step-by-step explanation:

this is correct because:

x-6=0

0*x=0

so

x^6
