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

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

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

kaheart [24]

Answer:

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 c.

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 c is -2.

Proportion of u/8=13/17

GalinKa [24]

$\dfrac{u}{8}=\dfrac{13}{17}\qquad\text{cross multiply}\\\\17u=(8)(13)\\\\17u=104\qquad\text{divide both sides by 17}\\\\\boxed{u=\dfrac{104}{17}}$
