Answer:
4.1 and 4.2
Step-by-step explanation:
or 4 and 5
The first thing you want to do is combine like terms. This means you should have all the x's on one side and the constants (numbers) on the other side. You can subtract 5x from both sides of the equation and then add 7 to both sides. This gives you -2x=26. Divide both sides be -2 to isolate the variable and your answer is x=-13. Hope this helped!

<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

Answer:
x = 4
Step-by-step explanation:
7x + 8 = 5x + 16
- 8 = - 8
7x = 5x + 8
-5x = -5x
2x = 8
/2 = /2
x = 4
