So what you would do is put in the 4 where ever you see an x. so it would look like -3(4)+9y=-57 then you solve for y. and the answer is -5. Make sense?
Omg I HATE IXL. the answer is 0.33333333333

Union and intersection of intervals
We are given the following intervals:


We need to find the union and the intersection of the intervals.
Both intervals are represented in the number line as shown in the figure below.
The union of intervals is the set of elements that belong to any of the intervals.
Since both intervals have no common area:

The intersection of intervals is the set of elements that belong to all the intervals.
As pointed above, there is no common area, thus the intersection is empty
