Answer:
A line that passes (2, 0) and (-6, 3) has slope:
S1 = (-6 -2)/(3 - 0) = -4/3
Another line that is perpendicular with above line has slope:
S2 = -1/S1 = -1/(-4/3) = 3/4
=> Option B is correct
Hope this helps

Answer:
We can take 2 plates , 3 plates or 6 plates.
Step-by-step explanation:
1 dozen = 12 numbers
Total number of cookies = 42
Each plate has to get atleast 7 cookies ,all the plates should have the same number of cookies and also the number of plates must be greater than or equal to 2.
- If we take 2 plates , there can be 21 cookies in each.
- If we take 3 plates , there can be 14 cookies in each.
- If we take 6 plates , there can be 7 cookies in each.
These are the 3 possible cases.
Since there cannot be broken pieces, no other combination is possible.
2/3
1/8
Would be the simplest forms
Given that initial time for jogging is,

After each week the time is increased by

This gives an arithmetic sequence.
To find n such that,

Therefore,

So,

Therefore, 9 weeks before you are up to jogging 70 minutes.
Answer:
4 1/5
Step-by-step explanation:
(2*3 is the same as 2x3 in multiplication)
Since in a week there are 7 days, you multiply the number of days to the distance walked per day. Which is 7*(3/5), or (3/5)*7
So (3/5)*7=4 1/5 or 4.2
(3/5)*7 equals
(3/5)+(3/5)+(3/5)+(3/5)+(3/5)+(3/5)+(3/5)=(21/5)
There are four 5's in 21, so it is 4 wholes.
4 an the remaining 1 over 5
=4 1/5
