Point R′ (−2, 8) is the image of point R (−2, 2). Which of the following algebraic representations could be used for that transf
insens350 [35]

Answer:

C) (x,y) → (x,y+6)

Step-by-step explanation:

As the x value stays the same after the transformation, we know that there can be no changes to the value x, automatically limiting the options to answer C.

The mathematical way to find the value y is changed by would be by setting up a small equation as follows:

8 = 2 + n, where n is some number that the y value is altered by.

Solving for n gives the value 6, proving that the translation must add 6 to the y value.

The area of a rectangular patio is 384 square feet.
Usimov [2.4K]

the ratio of the length and width = 3:2

Step-by-step explanation:

let the length be =x

width be = \frac{2x}{3}

area of a rectangle = length X width

so, x X \frac{2x}{3} = 384

or, x^{2} X 2/3 = 384

or, x^{2} = (384 X 3)/2

= 576

or, x = 24 ( taking square root)

hence, length is 24

width is = 24 X (2/3)

=16

so the ratio of length and width = 24 : 16

= 3:2
