If rectangle ABCD was reflected over the y-axis, reflected over the x-axis, and rotated 180°, where would point A′ lie? Rectangl

e formed by ordered pairs A at negative 4, 1, B at negative 4, 2, C at negative 1, 2, D at negative 1, 1. (1, −1) (1, 1) (−4, −1) (−4, 1) Question 9(Multiple Choice Worth 1 points) (02.02 LC) Pentagon ABCDE is shown on the coordinate plane below: Pentagon on coordinate plane with ordered pairs at A negative 2, 4, at B negative 6, 2, at C negative 5, negative 2, at D 1, negative 2, at E 2, 2. If pentagon ABCDE is rotated 180° around the origin to create pentagon A′B′C′D′E′, what is the ordered pair of point D′?

Create a circle with the origin as its center and a radius of the origin and point A, then locate a point on the circle that is 180° from point A. Create a circle with point A as its center and a radius of the origin and point A, then locate a point on the circle that is 180° from point A. Create a line parallel to the x‒axis from point A, and locate a point on the perpendicular line that is equidistant to the distance between the y-axis and A. Create a line perpendicular to the y-axis from point A, and locate a point on the perpendicular line that is equidistant to the distance between the y-axis and A.

Alexandra [31]

Answer:

28

Step-by-step explanation:

Let n = 21, and evaluate the expression.

a_n = -2 + \dfrac{3}{2}(n - 1)

a_{21} = -2 + \dfrac{3}{2}(21 - 1)

a_{21} = -2 + \dfrac{3}{2}(20)

a_{21} = -2 + \dfrac{3}{1}(10)

a_{21} = -2 + 30

a_{21} = 28

Which function passes through the points (2, 3) and (4, 4)?
Rina8888 [55]

Answer:

C. y=1/2x+2

Step-by-step explanation:

1. Find the slope using the slope formula.

Slope formula: y2-y1/x2-x1

Let the y-value in the second ordered pair (4,4) be y2, and the 3 in the first ordered pair (2,3) be y1. 4 and 2 from these ordered pairs will be x2 and x1.

Plug these values into the equation and simplify.

4-3/4-2

=1/2

Slope is 1/2

2. Choose one of the ordered pairs and plug those numbers and the slope into the point-slope formula.

Point slope formula: y-y1=m(x-x1). M represents the slope, and the x1 and y1 represent the values of the ordered pair.

Let's use the pair (4,4).

y-4=1/2(x-4)

3. Simplify the equation to convert to y=mx+b format.

Multiply the inside of the parentheses by 1/2.

y-4=1/2x-2

Add 4 to both sides.

y=1/2x+2

3. C is your answer, for it matches what you found in the calculations.
