Wolfgang and Heinrich worked as electricians at $14 and $12 per hour respectively. One month Wolfgang worked 10 hours more than
Licemer1 [7]

Let us say that:

x = hours worked by Wolfgang

y = hours worked by Heinrich

 

So that:

x = y + 10

14 x + 12 y = 3520

 

By combining the two equations:

14 (y + 10) + 12 y = 3520

14 y + 140 + 12 y = 3520

26 y = 3380

y = 130 hours

x = y + 10 = 140 hours

 

<span>So Wolfgang worked 140 hours while Heinrich worked 130 hours.</span>

Find the rule and the graph of the function whose graph can be obtained by performing the translation 3 units left and 2 units d
Leya [2.2K]

Answer: Option a.

Step-by-step explanation:

 1. You have the following parent function given in the problem above:

f(x)=x³ (This is the simplest form. We need to translate it 3 units left and 2 units down)

2. If you take the parent function and make y=f(x+3), then you have:

y=f(x+3)=(x+3)^{3} (The function is shifted 3 units left on the x-axis).

3. Then you if you make y=f(x+3)-2, as following, you obtain:

y=f(x+3)-2=(x+3)^{3}-2  (The function is shifted 2 units down on the y-axis).

4. Therefore, that is how you obtain the final function.

The answer is the graph shown in the option a.
