Missy's rotation maps point K(17, –12) to K'(12, 17). Which describes the rotation? 270 degrees counterclockwise rotation 90 deg
enyata [817]

Answer:

The correct option is;

90 degrees counterclockwise rotation

Step-by-step explanation:

The coordinates of the preimage before rotation = K(17, -12)

The coordinate of the image of the preimage after rotation = K'(12, 17)

Therefore, the rotation transformation, transforms, the preimage (x, y) to the image (-y, x), which is equivalent to a rotation of 90 degrees counterclockwise

At which values of x does the function F(X) have a vertical asymptote? F(X) =3/x(x-5)(x+1)
damaskus [11]

Answer:

There are vertical asymptotes at x:  {-1, 0, 5}

Step-by-step explanation:

It's easier (at least for some) if you write this function as

                  3

F(X) = ------------------

            x(x-5)(x+1)

Can you now see that if x = 0, this function is undefined?  Same for x = 5 and x = -1?  There are vertical asymptotes at x:  {-1, 0, 5}

The function p(x) = - 2(x-9)2 + 100 is used to determines the profit on T-shirts sold for x dollars. What would the profit from
dolphi86 [110]

ANSWER

$28

EXPLANATION

The profit function is given as:

p(x) =  - 2 {(x - 9)}^{2}  + 100

where x is the price of the T-shirt in dollars.

To find the profit on a T-shirt whose price is $15, we substitute x=15 into the function and simplify.

p(15) =  - 2 {(15 - 9)}^{2}  + 100

We simplify to get:

p(15) =  - 2 {(6)}^{2}  + 100

p(15) =  -72+ 100

p(15) =  28

-9x-6y=15,9x-10y=145
vazorg [7]

-9x-6y=15

9x-10y=145

Find y first by eliminating the x.

Add the two equations together.

-9x+9x-6y+-10y=15+145

-6y+-10y=15+145

-6y-10y=160

-16y=160

divide both sides by -16 to get +y

-16y/-16=160/-16

y=-10

Use the substitution method to find x

-9x-6y=15

-9x-6(-10)=15

Do the bracket first

-9x+60=15

Move +60 to the other side. Sign changes from +60 to -60.

-9x+60-60=15-60

-9x=-45

Divide both sides by -9

-9x/-9=-45/-9

x=5

Answer:

( 5,-10)
