Can Photomath solve absolute value equations?

Photomath can handle: quadratic equations, inequalities, simple equation systems, absolute value equations, absolute value inequalities, degrees to radians conversion and much more.

Are absolute value inequalities on the SAT?

We can break SAT and ACT inequalities questions down into three types: those involving a word problem, those involving algebra and those involving absolute values.

How to solve the absolute value inequalities?

The first thing I need to do is clear the absolute-value bars by splitting the inequality into two pieces. Then I’ll solve the two regular inequalities. This is the pattern for “greater than” absolute-value inequalites. This PAIR of inequalities is the solution to the original absolute-value inequality.

How to solve for less than inequalities in math?

Recall that with absolute values and “less than” inequalities, we have to hold the following: Otherwise written, this is: In this form, we can solve for y. First, we have to subtract x from all 3 parts of the inequality: Now, we have to divide each element by 3: What is a possible valid value of x? This inequality could be rewritten as:

Is there a solution to the absolute value problem?

In other words, absolute values are always positive or zero. Okay, if absolute values are always positive or zero there is no way they can be less than or equal to a negative number. Therefore, there is no solution for either of these.

How to calculate the absolute value of X?

For this problem, we must take into account the absolute value. First, we solve for 2 x – 2 > 20. But we must also solve for 2 x – 2 < –20 (please notice that we negate 20 and we also flip the inequality sign). Therefore, x > 11 and x < –9. A possible value for x would be –10 since that is less than –9.
