Answer:

A'(-4, 7) . . . . ending in quadrant 2

check switched coordinates for C', D'

Step-by-step explanation:

The transformations accomplished by rotations are ...

(x, y) ⇒ (-y, x) . . . . . 90° CCW or 270° CW

(x, y) ⇒ (y, -x) . . . . . 90° CW or 270° CCW

(x, y) ⇒ (-x, -y) . . . . 180° (either direction)

You notice that coordinates are switched and one is negated in each of these transformations. I assume that your line "Coordinates after the switch" is intended to lead you through that first step, then "New coordinates after rotation" is intended to be the same set of coordinates with the appropriate sign change.

1. A(7, 4) 90° CCW ⇒ (4, 7) ⇒ A'(-4, 7) . . . . ending in quadrant 2

2. B(-8, -1) 180° ⇒ B'(8, 2) . . . . ending in quadrant 1 (correct)

3. C(9, -5) 270° CW ⇒ (-5, 9)* ⇒ C'(5, 9) . . . . ending in quadrant 1

4. D(-6, -11) 90° CW ⇒ (-11, -6)* ⇒ D'(-11, 6) . . . . ending in quadrant 2

_____

* I would leave the original signs on the "coordinates after the switch". Here, you have dropped the signs. I don't know what you've been taught, but that's not how I would do it, as you can see above.

The table represents the total miles traveled, y, after a number of hours, x. Which linear equation represents the situation?
A. y=60x
B. y=60x+480
C. y=4x+240
D. y=270x

Answers

The correct answer is A! y=60x

Because when you take the number on the left side (hours, x) and multiply it by 60, you’ll get the answer in the right side (mile, y).

Like for example:

2.5 hour x 60 = 150 miles

Correct Answer: A

Explanation:
150/2.5 = 60
y= 60x

A ladder is placed against a wall. The foot of ladder is 3 feet away from the wall and the top of the latter hits the wall 15 feet of the ground. What is the slope of the ladder?
RIGHT ANSWERS ONLY!

Answers

Answer:

Step-by-step explanation:

The slope of the ladder is 5.

What is slope of a line?

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

Given that, the foot of ladder is 3 feet away from the wall and the top of the ladder hits the wall 15 feet of the ground.

We know that, slope = Rise/Run

Now, slope =15/3

= 5

Therefore, the slope of the ladder is 5.
