Since supplementary angles equal 180. (2x+15) = 45, which can be found by subtracting 135 from 180. This means that x = 15. And since angle 1 corresponds to the previous angle, we can deduce that angle 1 = 45.

Given the function f(x) = -2c+cx-x^2, and f^-1(5) = -1, find c
AnnZ [28]

Answer:

c=-2

Step-by-step explanation:

We are given the function:

f(x) = -2c + cx - x^2

And that:

\displaystyle f^{-1} (5) = -1

And we want to determine the value of <em>c</em>.

Recall that by definition of inverse functions:

\displaystyle \text{If } f(a) = b, \text{ then } f^{-1}(b) = a

So, since f⁻¹(5) = -1, then f(-1) = 5.

Substitute:

f(-1) = 5 = -2c + c(-1) - (-1)^2

Simplify:

5 = -2c - c - (1)

Combine like terms:

6 = -3c

And divide. Hence:

c = -2

In conclusion, the value of <em>c</em> is -2.

I need your help! Will give brainiest!

Answer:

$128,270

Step-by-step explanation:

Hello!

The income amount $168,050 fits into the fourth line of the table ($82,250-$171,550).  The tax on $168,050 is found as follows:

$16,750 plus 0.28 times the amount over $82,250.

Let's figure the tax:  $16,750 + 0.28($82,250) = $16,750 + $23,030, or

$39,780.  If this tax is deducted from the person's gross pay, the amount left ("take home pay") will be $168,050 - $39,780, or $128,270.
