Which sequences of transformations will map circle<br><br> M onto circle N?
sergiy2304 [10]

Answer:

1: Reflect M across the x-axis

2: Dilate about the center by 3/2

Step-by-step explanation:

Given

See attachment for M and N

Required

Which maps M to N

The coordinates of the radius of the circles are:

M = (5,5)

N = (5,-5)

And the radius of circles are:

r_M=2

r_N=3

The first transformation from M to M' is:

- Reflect across the x-axis

The rule is:

(x,y) \to (x,-y)

M(5,5) \to M'(5,-5)

<em>At this point, M' and N now have the same center but different radius.</em>

The second transformation from M' to N is:

- Dilate about the center by dividing the radius of N by the radius of M

i.e.

k =\frac{r_N}{r_M}

k =\frac{3}{2}

<em>At this point, M has been completely mapped to N.</em>

Complete the solution of the equation find the value of y when x equals 2. -8x - 5y = -1
tatuchka [14]

Answer: y = -3

<u>Step-by-step explanation:</u>

-8x - 5y = -1

<u>+8x        </u>  <u>+8x </u>

       -5y = 8x  - 1

       <u> ÷-5 </u> <u> ÷-5</u>  <u>÷-5</u>

           y = -\frac{8}{5}x + \frac{1}{5}

       y(2) = -\frac{8}{5}(2) + \frac{1}{5}

               = -\frac{16}{5} + \frac{1}{5}

               = -\frac{15}{5}

                = -3

A customer enters an order to buy 1,000 abc at 50, good for the week only. how will this order appear on the order book?
marysya [2.9K]

This isn't math.

GTW means good this week, so choice b.

Don't ever put in GTW orders; it's pretty much asking to be robbed.
