Question:
Solve for x: . Fill in both values for x below. Write the greater value for x in the first column.
Answer:
and
are the values for x.
Explanation:
The equation is
Subtracting both sides by 7,
Dividing both sides by 12,
Now, we shall write the equation by removing modulus by adding plus and minus on the other side of the equation.
or
Solving the equation , we get,
or
Thus, the solutions are and
It had taken a while for me to understand the problem. From what I understood, the given pairs of points are tabulated below:
x f(x)
-7 -11
-1 1
3 9
4 11
7 17
Then, the choices are equations in terms of x. The correct equation should yield the pairs tabulated above when the x-values are substituted into the equation. So, the solution is basically just substituting x to each of those equations, then you get the corresponding y values. Check which of those question has pairs similar to the given. I suggest that you tabulate the numbers so that it would be easier for you. For me, I used MS Excel as shown in the picture. Th x-values are in the first column gathered from the given. I applied the equations to get the f(x) values. As you can see, the pairs matched with the third column. Therefore, the answer is: f(x) = 2x+3.
