Answer:
Step-by-step explanation:
From the given picture, it cam be seen that the two triangles are reflection of each other.
Such that their corresponding x coordinate has different sign but same magnitude and the corresponding y-coordinate remains unchanged.
Thus, the reflection must be reflection across y-axis.
The rule of the reflection across y-axis is given by:-
Answer:
The value of x that makes the equation true is 3
Explanation:
From the attached image;
Let us write the mathematical equation of the model.
The long bar means x, while the small squares have a value of 1 each.
solving the equation we have;
Therefore, the value of x that makes the equation true is 3
