Answer:
2y
Step-by-step explanation:
Simplifying
21x + -42y = 0
Solving
21x + -42y = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '42y' to each side of the equation.
21x + -42y + 42y = 0 + 42y
Combine like terms: -42y + 42y = 0
21x + 0 = 0 + 42y
21x = 0 + 42y
Remove the zero:
21x = 42y
Divide each side by '21'.
x = 2y
Simplifying
x = 2y
Answer:
(6,5)
Step-by-step explanation:
okay so the original point is (1,4). we know 1 is our X which is the one that is going up. and 4 is our Y which is going to the right. if you are moving 5 units to the right you will add 5 to 1 (our original x) which equals 6. And going 1 unit up our original Y is 4 so we add the 1 and now we get 5. our new point is (6,5)
I am not sure but I think is the last one!!!!
