Y = 2
y = 4x - 10
2 = 4x - 10
2 + 10 = 4x
12 = 4x
12/4 = x
3 = x
solution is : (3,2)
Answer:
(C) Division Property of Equality
Step-by-step explanation:
Looking at the equation
, we see that if we want to isolate y, we need to divide it by 2 - because we're multiplying it by 2, and 2 times a number divided by 2 is just the number.
The Division Property of Equality states that if we have an equation,
, then
.
So, that means
will be equal to
, which is 9.
Hope this helped!
The answer is C because it’s the only answer that could be correct.
Some textbooks describe direct variation by saying " y varies directly as x ", " y varies proportionally as x ", or " y is directly proportional to x . ") This means that as x increases, y increases and as x decreases, y decreases—and that the ratio between them always stays the same.
