Answer:
3x-y=1 is in the form Ax+By=c
where A=3, B=-1, C=1
Step-by-step explanation:
we have to convert the equation y-5=3(x-2) to the form Ax + By = C.
the equation y-5=3(x-2) is in the form
which is the point slope form of a straight line in cartesian coordinate.
where m is the slope of the line and is the point through which the line is passing through.
therefore y-5=3(x-2) becomes y-5 = 3x-6
y-5+6=3x
y+1=3x
3x-y=1
this equation is in the form Ax+By=c
therefore comparing these two equations we get
A=3, B=-1, C=1
Answer:
Given,
2 cups of yellow paint is needed for every 3 cups of red paint to make a batch of orange paint,
So, the ratio of yellow paint and red paint in a batch of orange paint = 2 : 3
Make two number lines,
First one represents the multiple of 2 and second one represents the multiples of 3,
By the double number line ( shown below ),
It is clear that,
For 3 batches of orange paint, 6 cups of yellow paint and 9 cups of red paint are needed.
