Answer:
4y = -3x +30
Firstly you have to look for the gradient or slope using the points given in the question.
Then substitute the gradient (m) into y= mx+ c
Answer:
20 days
Step-by-step explanation:
t = time required by one worker to complete the job alone
(t+8) = time required by the other worker
So:
7.5/ t + 7.5/ (t + 8) = 1
Solve for t.
...
t = 12 days, the first guy working alone
The other worker would finish the job in 20 days.
(1/2)x+b=y because the equation that given the slope is 1/2 if you leave y alone and take the x’s number
put the point now , 4+b=3 so b is -1
the equation is (1/2)x-1=y
If you round the 6. Or if they ask u to round the tenth place or ones place and do the opposite or something else
