2x + y - (x + y) = 3z - 6z 
--------------------------------------------------------
<span>x = -3z </span>
------------------------------------------

<span>(-3z, 9z) </span>
 ----------------------------------
<span>(x,y,z) = (-3z, 9z, z) 
</span>--------------------------
<span>x = -3z, y = 9z
---------------------
There for the answer is </span><span>(-3z, 9z) </span>

Which dot plot has the largest range?
romanna [79]

Answer:

Calico Crayfish has the largest range ⇒ The range = 9

Step-by-step explanation:

∵ The rang is the difference between the largest value

   and the smallest value

In the Calico Crayfish the largest value is 10 and the smallest value is 1

∴ The range = 10 - 1 = 9

In the Zebra Mussel the largest value is 10 and the smallest value is 2

∴ The range = 10 - 2 = 8

In the Blue-back Herring the largest value is 10 and the smallest value is 4

∴ The range = 10 - 4 = 6

In the Shield Darter the largest value is 9 and the smallest value is 2

∴ The range = 9 - 2 = 7

∴ The largest range is 9 in Calico Crayfish

12.  \frac{r-3}{-4-(-8)} =  -5
\frac{r-3}{4} = -5
r - 3 = 4(-5)
r - 3 = -20
r = -20 + 3
r = -17

13.  \frac{r-2}{-2-5} = \frac{5}{6}
\frac{r-2}{-7} =  \frac{5}{6}
6(r - 2) = -7(5)
6r - 12 = -35
6r = -35 + 12
6r = - 23
r = \frac{-23}{6}
