Which of the following shows why rectangle WXYZ is congruent to rectangle W'X'Y'Z'?
blsea [12.9K]

If you rotated the box 90º, the orrientation would not be the same, so it is not D or B.

After rotating 180º, the box will be in the 1st quadrant. If it moved along the x-axis, it wouldnt be there anymore, and the after-picture shows it in the first quadrant still, so the only answer it can be is C.

determine if f(x)=4x+1/x*5 and g(x)=5x-1/x+4 are inverses of each other. if they are not inverses, explain why.
kherson [118]

f(x) = \frac{4x+1}{5x}                     g(x) = \frac{5x-1}{x+4}

g⁻¹(x): x = \frac{5y-1}{y+4}

       x(y + 4) = 5y - 1           <em>multiplied both sides by y + 4</em>

       xy + 4x = 5y - 1           <em>distributed x into y + 4 on left side</em>

  xy + 4x + 1 = 5y                <em>added 1 to both sides</em>

          4x + 1 = 5y - xy          <em>subtracted xy from both sides</em>

           4x + 1 = y(5 - x)         <em>factored y on the right side</em>

           \frac{4x+1}{5 - x} = y         <em>divided 5 - x from both sides</em>

f(x) ≠ g⁻¹(x)  so they are not inverses of each other

Answer: NOT INVERSES because f(x) ≠ g⁻¹(x)

List the following events in the order in which they happened. Gold is discovered in Georgia. Jackson supports the Indian Remova
evablogger [386]
These events are actually already placed in the order in which they happened:

1. gold is discovered in Georgia - this happened in 1828, when the actual Gold Rush started - everyone wanted to get a hold of some gold

2. Jackson supports the Indian Removal Act with force - the Act was signed in 1830, and meant that Native Americans were supposed to be kicked out of their land so that America could take them over

3. the Supreme Court says Georgia Indian laws are unconstitutional - this happened in 1832, which meant that Georgia didn't have any authority to implement such laws
