Answer:
Step-by-step explanation:
Given the following equation:
You can follow these steps in order to solve for "x" and find its value:
1. Apply Distributive property on the right side of the equation:
2. Subract from both sides and add the like terms:
3. Subtract 1.8 from both sides:
4. Finally, divide both side of the equation by -1.5:
Answer:
Option b
Step-by-step explanation:
To write the searched equation we must modify the function f (x) = | x | in the following way:
1. Do y = f(x + 4)
This operation horizontally shifts the function f(x) = | x | by a factor of 4 units to the left on the x axis.
y = | x +4 |
2. Do
This operation horizontally expands the function f (x) = | x | in a factor of 4 units.
3. Do
This operation vertically shifts the function f (x) = | x | by a factor of 4 units down on the y-axis.
4. After these transformations the function f(x) = | x | it looks like:
Therefore the correct option is option b. You can verify that your vertex is at point (-4, -4) by making f (-4)
