{a }^{2}  +   {b}^{2} =  {c}^{2}

{1}^{2}  +  {x}^{2}  =  {2}^{2}
{x}^{2}  =  {2}^{2}  - {1}^{2}
{x}^{2}  = 3 \\  \\ x =  \sqrt{3}
\sqrt{3}  = 1.73

X + 1 = 2 x +1 In the equation above, which choice is a possible value of x + 1?
kaheart [24]

Answer:

1

Step-by-step explanation:

First, we need to find the solution to the system of equations. If x+1 = 2x + 1 , solving for x we have that: x=0.

Given that x=0, the possible value of x+1 = 0 +1 = 1.

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.
