Answer:

90º clockwise rotation

Step-by-step explanation:

The rotation is a 270º counterclockwise rotation, since 270º rotation is

(x, y) → (y, -x)

F(1, 3) → (3, -1)

270º counterclockwise rotation is the same as a 90º clockwise rotation, so the answer is 90º clockwise rotation.

if y varies directly as x and y is 48 when x is 48 when x is 6 which expression can be used to find the values of y when x is 2

Oksanka [162]

Answer:

the expression is

y=8x

Step-by-step explanation:

y varies directly as x is written as

$y \alpha x$

introducing constant

y=kx

from the question, when y=48, x=6

substitute it in the formula

48=6k

making k the subject by dividing through by 6

$\frac{48}{6} = \frac{6k}{6}$

k=8

putting the value of k in the expression,

y=8x

the value of y when x=2

y=8×2

y=16

thus the value of y when x=2 is 16.

The vertices of a parallelogram are shown below.

OleMash [197]

The vertices for the dilated image can be found by multiplying the coordinates of the original image by the scale factor. In this problem, the scale factor is 1/3.

(0,0) ⇒ 0 x 1/3 = 0 ; 0 x 1/3 = 0 ⇒ (0,0)
(27,0) ⇒ 27 x 1/3 = 9 ; 0 x 1/3 = 0 ⇒ (9,0)
(36,30) ⇒36 x 1/3 = 12 ; 30 x 1/3 = 10 ⇒ (12,10)
(9,30) ⇒ 9 x 1/3 = 3 ; 30 x 1/3 = 10 ⇒ (3,10)

Answer is choice D. (3,10)

Which of the following is the general term for the sequence? -a, a^2, -a^3, a^4,...

Elis [28]

Answer:

The answer would be $-a(-a)^{n-1}$ .

Step-by-step explanation:

We can simply substitute the terms into this equation. Checking the 1st term, $-a(-a)^{1-1} = -a(-a)^{0} = -a(1) = -a$ . Moving on to the second term, we see $-a(-a)^{2-1} = -a(-a)^{1} = -a(-a) = a^{2}$ . And so on and so forth. We can see how the answer fluctuates between negative and positive, while gaining one more exponent every term, which fits with the sequence given. Therefore, the answer would be $-a(-a)^{n-1}$ .

Hope this helped!
