The answer is 4. 2x plus 7 is equal to 15. First you subtract 7 from both sides then divide by 2 to get the answer 4. Hope this helps!

Step-by-step explanation:
<u>Domain And Range Of A Function</u>
Let y=f(x) a real function. We call the domain of f to every possible value x can take that produces one real value for y. The range of f, is the set of all those values y can take when we take every possible element from the domain.
In the image, we can see the graph of a function who takes values of x without restriction, if x was greater than the maximum value shown in the graph, f(x) will take greater values also. The same happens if x was smaller than the minimum value shown in the graph. We can conclude the domain of x is
We can also see the values of y come from , then reach a minimum value of -2, and then increases without limits to . This means the range is
50x12= 600 then 3x12 =36
so
600-36= 564
