1 answer:

6 0

Use this formula: $d= \sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }$

a) d=11

Work:
d=sqrt((4-(-7))^2+(5-5)^2
d=sqrt((11)^2+(0)^2)
d=sqrt(121+0)
d=sqrt(121)
d=11

b) d=4

c) d = 16

d) d=160

e) d=12

City R has a temperature of -2 degrees. City S has a temperature of -6 degrees. Write an inequality to compare the temperatures

Answer:

-2 > -6 . . . or . . . R > S

Step-by-step explanation:

If you plot the temperatures of the two cities on a number line, you see that the temperature for City R is plotted to the right of the temperature for City S. This means the temperature of City S is less than that of City R.

If your inequality relates cities:

S < R or R > S

If your inequality relates temperatures:

-6 < -2 or -2 > -6
