Answer: x > 5
Step-by-step explanation: To solve for <em>x</em> in this inequality, our goal is the same as it would be if this were an equation, to get x by itself on one side.
Since 3 is being subtracted from x, we add 3 to
both sides of the inequality to get x > 5.
When graphing x > 5, we have an open circle on 5 and the
open circle tells us that 5 is not part of our answer.
Then we draw an arrow going to the right to represent
all possible solutions to this inequality, any number greater than 5.
Answer:
7
Step-by-step explanation:
The given equation is
First we solve for y, and for that, we have to islolate y, that is
And it pass the vertical line test. So here y is a function of x .
So we can define the given equation as y as a function of x .
