P = paddling speed
C = speed of the current
Upstream: 6 = 4 (P - C. Downstream: 6 = 3 (P + C)
4P - 4C = 6
3P + 3C = 6
12P - 12C = 18
12P + 12C = 24
Add the equations:
24P = 42. P = 42/24 = 1.75 mph
Subtract the equations:
-24C = -6
C = 0.25 mph
Answer:
Resulting plot in the image attached
Step-by-step explanation:
Start by making a table of (x,y) pairs that satisfy this equation. Notice that two pairs would be enough, but it is always safer to obtain at least three to see them actually "aligned".
We are trying to find values for y when x= 0, 2, and 4 to make our calculations simple:

When x = 0 then:
So we plot the value (0,-3) on the x-y plane.
When x = 2 then:
So we plot the value (2,-2) on the x-y plane.
When x = 0 then:
So we plot the value (4,-1) on the x-y plane.
Please see the points and the resulting line in the image attached
25 remainder 6 is how many times
Answer:
X = 1
Y = -3
Step-by-step explanation:
The Cartesian coordinate system, also called the rectangular coordinate system, is based on a two-dimensional plane consisting of the x-axis and the y-axis.
So the ratio of the first engine is 4 gasoline: 1 oil. 4:1 ratio. So the question is asking __ gasoline: 5 oil? Simple. For every 1 part of oil is 4 parts gasoline, so for the answer, you'd cross multiply.
