Step-by-step explanation: Please think this through, I don't know if I'm correct. It is either all or one of these
Answer:
it depends
Step-by-step explanation:
If 17 is the hypotenuse
if you are looking for the hypotenuse
Standard form is just putting (in this case) variables in alphabetical order. First we simplify- 2x+4=4y would become 1/2x+1=y. This is already in standard form, as numbers w/o variables come at the end. simplifying the next one is more tricky. first you get a variable/number alone-
9-2x-2y=4x+3
9-2y=6x+3
6-2y=6x
1-1/3y=x
1=x+1/3y
3=x+y
x+y=3
sorry if I was wrong and not of any help, But I do believe this is correct.
