Which sequence of transformations takes figure b to its image b'?
a. a reflection in the y-axis, followed by a translation 6 units up
b. a reflection in the x-axis, followed by a translation 2 units left
c. a reflection in the x-axis, followed by a counterclockwise rotation of 180 about the origin
d. a reflection in the y-axis, followed by a counterclockwise rotation of 270 about the origin

D. a reflection in the y-axis, followed by a counterclockwise rotation of 270 about the origin

Step-by-step explanation:

Well, the first obvious step is to reflect it across the y-axis. Now, for the next step, since we do not have a 90°-clockwise rotation option, we have to go with something similar to that, which would be a 270°-counterclockwise rotation. If you think about it, since 3 × 90 is 270, and rotating this figure 90° clockwise [one rotation] would go from Quadrant III to Quadrant II, going the other way around [270°counterclockwise (three rotations)] will also go from Quadrant III to Quadrant II [to Quadrant to Quadrant I to Quadrant II].

I am delighted to assist you anytime my friend.

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)
