what is the distance between (0.-3) and (9.6)
Answers
Answer:
d = 12.7 when rounded to the nearest tenths
Step-by-step explanation:
Distance formula:
d=√((x_2-x_1)²+(y_2-y_1)²)
Your ordered pairs (0, -3) and (9, 6)
d=√((9-0)²+(6-(-3))²)
d=√((9))²+(6+3))²)
d=√(81 + (9)²)
d = √162
d = 12.727...
d = 12.7 when rounded to the nearest tenths

Option 2
Step-by-step explanation:
Given function:
x=8 and y=6x=5 and y=20Option 1: ×
Table one: y=8-6
if y is 6 then 8-6 can’t be 6 it is 2.
Option 2: √
Table one:
y=8-2
y would be 6 then this would be correct..
Table two:
y=4x
if y=20 then x would be 5 and if y is 16 then x=4.
Option 3:×
y=4x
this is wrong since table 2 is y=4x..
Option 4:×
Table one
y=x-4
if y is 6 and x is 8 then this is wrong..
Therefore, option 2 is correct..
