To round to the nearest ten you would look one place to the right from the tens place. if this number is greater than or equal to 5 you round up, if it is less than 5 you round down.
in this case the tens place is a 2, and to the right we have a 6 in the ones place.
6 is greater than 5 so we round up.
626 rounded to the nearest ten is 630
Answer:
5y=9x-2
y=mx-b
m=slope
y=9/5x-2/5
m=9/5=1.8 slope of pArallel
slope of pARALLEL=-1/M SLOPE OF A LINE PERPENDICULAR
m=-5/9 slope of a line perpendiculr
Answer:
60
Step-by-step explanation:
Answer:
-11
Step-by-step explanation:
y=-7-4= -11
We can rearrange the initial equation to y=mx+b
y=2x-5
Since perpendicular slopes must equal -1,
x=the perpendicular slope
2x=-1
x=-1/2
(Or you can just take the negative reciprocal above is just the "formula form" for it)
Therefore, the perpendicular slope is -1/2
