Plug in the numbers on the x axis (the ones in the x row) where the x in the problem is.

Since the x is right next to -10 you multiply the number you plug in by -10.

Then, subtract that from 4 and you have your answer!

Answer:

$\displaystyle Bottom\:Right\:Graph$

Step-by-step explanation:

Use the zero-interval test [test point (0, 0)] to verify them as false or true, and to determine whether we shade the shared opposite portions [a shared portion that does NOT contain the origin] or the shared portions that DO contain the origin:

$\displaystyle 0 ≤ 0 - 2 → 0 ≰ -2$

$\displaystyle 0 < -3[0] - 2 → 0 ≮ -2$

So, this system will be shaded in a shared opposite portion.

*NOTE; Both inequalities have an identical y-intercept of $\displaystyle [0, -2],$ so both inequalities must intersect the y-axis at $\displaystyle [0, -2],$ and since there are already lines labeled as <em>dashed</em><em> </em>and solid, we do not have to worry about it in this case.

** None of the other graphs match this, so the bottom right graph has to be it, considering it cut off.

Write the equation for the graph of y = | x | translated left 4 units

Lerok [7]

Answer: y = |x+4|

Explanation:

Imagine that the graph of y = |x| is carved in stone so it cannot move. What we can move though is the xy axis. If we move the xy axis 4 units to the right, then this gives the illusion the V shaped curve is moving 4 units to the left. It goes opposite whatever movement you do to the xy axis.

If we replaced x with x+4, then this moves the xy axis 4 units to the right.

Therefore, going from y = |x| to y = |x+4| will have the V shaped curve moving 4 units to the left.
