Answer:
15
Step-by-step explanation:
Let index 1 refer to the first point, while index 2 refers to the second one.
The distance d:
d²=(x2-x1)²+(y2-y1)²=(-5-7)³+(3-(-6))²=
(-12)²+9²=144+81=225=15²
d=15
Answer:
Subtract both sides by 7
Step-by-step explanation:
We have to make sure that we isolate the x term first. So we must subtract 7 from both sides.
Recall that for
, we have

Replace
with
and we get

Lastly, multiply this by
, so that

34/3 = 11 1/3 = 11.3333....
