Kn + 4f = 9f
kn + 4f - 4f = 9f - 4f
kn = 5f
kn/5 = 5f/5
kn/5 = f.
f = kn/5 or
f = 1/5 (kn).
I'm going to do this on paint and upload it.
Hope this helps
Answer: Choice C
The pink equation is y = 2x-3
The yellow equation is y = -2x+1
Notice how the pink equation crosses the y axis at (0,-3) or at -3 on the y number line. This tells us that the pink equation has a y intercept of -3. So b = -3
This only happens with the equation y = 2x-3. The other equations do not have a y intercept of -3. So this quickly rules out the other choices leaving C as the only answer.
An alternative is to find two points on the pink line, such as (0,-3) and (1,-1). Then find the slope of the line through those points. You should find the slope to be m = 2. So m = 2 and b = -3 leads to y = 2x-3. Follow similar steps for the yellow line as well.

Answer:
Step-by-step explanation:
you set the equation and try to bring it over one
i will do one of them for you
$9.40 for 5 cans of soup
to find what one can costs, divide 9.40 by 5
and you get $1.88
or you can set a proportion
9.40 x
--------- = ----------
5 1
cross multiple
5x=9.40
x=1.88
