Answer:
n = -40/9
Step-by-step explanation:
Let n = the number
(1/2)n - 2/3 = (1/5)n - 2
Multiply both sides by 30, which will get rid of the fractions.
15n - 20 = 6n - 60
9n = -40
n= -40/9
Hope this helps.
I’m sorry if I’m wrong but from what I know (if it’s the same question) is 2,3
Answer:
B. Point B is opposite of Point C
Step-by-step explanation:
Let B (x1, y1) and C (x2, y2) be two points.
if sum of B and C is 0:
([x1 + x2]/2, [y1 +y2]/2 ) = (0, 0)
then
[x1 + x2]/2=0 then x1+x2 = 0 then x1 = -x2
similarly, [y1+y2]/2 = 0 then y1+y2 = 0 then y1=-y2
Therefore,
B= (-x2, -y2) while C = (x2, y2)
To form the vector notation for the translation:
--> must find how much the new graph moved horizontally from the old
graph
--> <u>the graph moved 8 units horizontally</u>
--> must find how much the new graph moved vertically from the old
graph
--> <u>the graph moved 4 units vertically</u>
<u />
<u />
In vector notation, that would be <u>(8,4)</u>
<u></u>
Hope that helps!
