Answer:

  b = 10

Step-by-step explanation:

a) Solve by inspection. b=10 makes both fractions equal to 1.

Both the numerator and denominator of the fraction on the right are 2 greater than those of the fraction on the left. The fractions will be equal when numerator and denominator are equal.

__

b) Multiply by 60 and solve in the usual way.

  6b = 5(b+2)

  b = 10 . . . . . . . . . . subtract 5b

__

c) Expand the fraction on the right, subtract the variable term.

  b/10 = b/12 + 2/12

  b(1/10 - 1/12) = 1/6

  b/60 = 1/6 . . . . simplify

  b = 60/6 = 10 . . . . multiply by 60

<em>Comment on the question</em>

There is no "y", so you cannot solve for y. This is another example of poor quality control (editing) of math curriculum materials. It is my sincere wish that you not have to put up with that. Math is tough enough without this added confusion.

sleet_krkn [62]

Answer:

Step-by-step explanation:

Answer:

(-5, 1)

Explanation:

We are given a kite on the graph which is rotated 180° clockwise about the origin and then reflected over the Y axis followed by reflection over the X axis.

We are to find the coordinates of point A after the complete transformation.

A (-5, 1)

When a point is rotated 180° clockwise about the origin, the signs of its coordinates change.

A (-5, 1) ---> A' (5, -1) - after clockwise rotation of 180 degrees about origin

Then this point A' is reflected over the Y axis where the y coordinate remains the same but x coordinate changes its sign.

A' (5, -1) ---> A'' (-5, -1) - after reflection through y axis

Now this point A'' is reflected over the X axis where the x coordinate remains the same while y coordinates changes its sign.

A'' (-5, -1) ---> A''' (-5, 1) - after complete transformation

Answer:

22 posts

Step-by-step explanation:
