To solve this problem, we need to use the distance formula.

Distance = $\sqrt{(x2 - x1)^2 + (y2 - y1)^2}$

x1 = -9

x2 = 2

y1 = -7

y2 = -6

Plug your numbers in

Distance = $\sqrt{((2) - (-9))^2 + ((-6) - (-7))^2}$ . Simplify each parenthesis.

Distance = $\sqrt{121 + 1}$ . Add these numbers together and take the square root.

Distance = √(122) or 11.05 units.

Answer:

$\sqrt{122}$

subtract the x from the other x and the y from the other y. Put that equation in a square root.

15% of 52.95 is 7.94

so they should tip $7.94

Let f(x) = x+2/x+6 <br> f^-1(-6) =

GREYUIT [131]

We can explicitly find the inverse. If $f^{-1}(x)$ is the inverse of $f(x)$ , then

$f\left(f^{-1}(x)\right) = \dfrac{f^{-1}(x)+2}{f^{-1}(x)+6} = x$

Solve for the inverse :

$\dfrac{f^{-1}(x) + 2}{f^{-1}(x) + 6} = x$

$\dfrac{f^{-1}(x) + 6 - 4}{f^{-1}(x) + 6} = x$

$1 - \dfrac4{f^{-1}(x) + 6} = x$

$1 - x = \dfrac4{f^{-1}(x) + 6}$

$f^{-1}(x) + 6 = \dfrac4{1-x}$

$\implies f^{-1}(x) = \dfrac4{1-x} - 6$

Then when x = -6, we have

$f^{-1}(-6) = \dfrac4{1-(-6)} - 6 = \dfrac47-6 = \boxed{-\dfrac{38}7}$

Alternatively, we can first solve for x such that $f(x) = -6$ . Then taking the inverse of both sides, $x = f^{-1}(-6)$ . (The difference in this method is that we don't compute the inverse for all x.)

We have

$\dfrac{x+2}{x+6} = -6$

$x + 2 = -6 (x + 6)$

$x + 2 = -6x - 36$

$7x = -38$

$\implies x = \boxed{-\dfrac{38}7}$

Find the possible value or values of n in the quadratic equation 2n2 – 7n + 6 = 0.

nika2105 [10]

$2n^2 - 7n + 6 = 0\\
2n^2-4n-3n+6=0\\
2n(n-2)-3(n-2)=0\\
(2n-3)(n-2)=0\\
n=\dfrac{3}{2} \vee n=2

Drag a description to match each equation

ivanzaharov [21]

Hi,

Answer:

1) y = 2x - Multiplicative: y is 2 times x

2) y= x +2 - y is 2 more than x

<u>My work:</u> These are the right answers, because whenever there is an variable such as x next to a number it’s means to multiply. The second would be y is more than x because one the other two are for x values and two, because in this problem you add.

I Hope I Helped!
