The coordinates of B would be C. (4, -8)

I got this because when reflecting over the x axis, the only value that changes is the y value. If you graph it out, the y value is the opposite while the x is the same.

Hope this helps!

Cara and Jena, working together, can clean the house in 4
kirill115 [55]

Answer:

\frac{4}{3}hrs/house

Step-by-step explanation:

Rate is the amount of work done per unit of time;

  Let Cara's rate  = C

   Let Jena's rate  = J

        C + J  = 4  ------ i

Now;

  Working alone:

             Jena takes twice as long as Cara

                          J  = 2C  ---- i

How long does it take Cara to clean a house alone

           C + J  = 4

             J = 2C

        C + 2C = 4

           3C = 4

              C = \frac{4}{3}hrs/house
