Simplifying

12x + 10 + 3 + 8x = 0

Reorder the terms:

10 + 3 + 12x + 8x = 0

Combine like terms: 10 + 3 = 13

13 + 12x + 8x = 0

Combine like terms: 12x + 8x = 20x

13 + 20x = 0

Solving

13 + 20x = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-13' to each side of the equation.

13 + -13 + 20x = 0 + -13

Combine like terms: 13 + -13 = 0

0 + 20x = 0 + -13

20x = 0 + -13

Combine like terms: 0 + -13 = -13

20x = -13

Divide each side by '20'.

x = -0.65

Simplifying

x = -0.65

The graph of y = tan ⁡(x − π / 2) compared to the graph of y = tan ⁡x has:
vodomira [7]

Answer:

Last Option moved \frac{\pi}{2} units right

Step-by-step explanation:

If we have a function f(x) and we want to move it horizontally then we make the transformation:

y = f (x + h)

If h then the graph of f(x) moves horizontally h units to the right

If h> 0 then the graph of f(x) moves horizontally h units to the left.

In this case we have the function y = tan (x) and the transformation is performed to obtain y = tan(x- \frac{\pi}{2})

Notice that in this transformation

h

<u><em>Then the graph of y = tan (x) moves horizontally \frac{\pi}{2} to the right</em></u>

Archie earns $4 a week for doing choirs. How much will Archie warm in 2 months if there are four weeks in each month?
siniylev [52]

Hello! The answer for your question would be $32. This is because if Archie earns $4 a week and there are 4 weeks in each month, and he works for 2 months, then 4*4 for one week would equal $16. This times 2 would equal $32 therefore, Archie earned $32 dollars for 2 months of doing chores.
