Answer:

Reflected about the y-axis and then rotated 90° counterclockwise

Step-by-step explanation:

(x , y) to (-x , y) --> reflected over y-axis

then (-x , y) --> (-y, -x) -->90 degrees rotation counterclockwise

So answer is the last one

The translation of ABCD to A'B'C'D'<br> is given by (×+[?].y-[ ]).

Answer:

(x + 1 , y - 3)

Step-by-step explanation:

Compare x-coordinate of A(-6,1) and A'(-5,-2)

-6 + a = -5

a = -5 +6 = 1

x- coordinate of A' = x coordinate of A + 1

Compare y-coordinate of A(-6,1) and A'(-5,-2)

1 + a =-2

a = -2 - 1 = -3

y- coordinate of A' = y coordinate of A - 3

A(-6 , 1) = A'(-6+1 , 1-3) = A'(-5, -2)

D(( -1 , 1) = D'(-1+1, 1 - 3) = D'(0,-2)

C(-2,3) =C'(-2+1, 3-3) = C'(-1,0)

B(-4,3)= B'(-4+1 , 3-3) = B'(-3,0)

In what ways was the introduction of imaginary numbers similar to the introduction of negative numbers and the introduction of i

raketka [301]

The introduction of imaginary numbers similar to the introduction of negative numbers through the determination of square root of a negative number.

<h3>Imaginary numbers </h3>

Complex numbers are square root of a negative number. Since a square root of a negative number cannot be determined, it is always represented with "i"

Given the rational number √-4 for instance, this will result in complex number or imaginary number since it is a negative number.

The equation through the point (-2, 5) and is parallel to the line with the equation y=2x+7

andrezito [222]

If a line is parallel to y=2x+7 the line must have the same slope but different y- intercept. The equation y=2x+7 has a slope (m) of 2 and y- intercept of 7.

By using the point slope formula and the point (-2,5) we have:

$y = m(x -x1) + y1 \\ \\ y = 2(x - ( - 2)) + 5 \\ \\ y = 2(x + 2) + 5 \\ \\ y = 2x + 4 + 5 \\ \\ y = 2x + 9$
