I hope this helps you
y=5x+6 this lines slope= -5
-3 (6x-y)= -54
6x-y= 18
y= 6x-18 this lines slope= -6
parallel lines slopes equal
-5 is not equal -6 not parallel
6 and 4/7 is a mixed number that is equal to 46/7
Answer:
823*53=43619
Step-by-step explanation:
I use the following method when it comes about products of big numbers
I grab the longer and put on the first line, below I put the smallest number
823
x 53
Now just is matter of performing 2 products
823*3 which goes in a line below the prior
823*5 which goes in a line below the prior, and put an extra zero to the right
At the end of it, just sum the terms from two lines above
823*3= 2469
823*5=4115 (with no extra zero)
So
823
x 53
-------
2469
41150 (with extra zero)
---------
43619
