yes the situation is directly proportional, because the slope is consistent.<span />
Answer:
y=x-8 and y=-x+4
Step-by-step explanation:
The slopes of the lines can be anything, as long as they are the opposite reciprocals of each other. Then you can plug in the point for x and y to solve for b in both lines (for y=mx+b where m is the slope)
Answer:
x=0.18 repeating
Step-by-step explanation:
Solve the rational equation by combining expressions and isolating the variable x

HI THERE!
i can help you :)
------------------------------------------------------------------------------------------------------------------
let the number of raisins (in pounds) be R and the number of peanuts (in pounds be p.
since the bag is 30 pounds, so R+P =30
the total cost of the bag is 30 pounds* 4.05 per pound = $121.50 .
now we can use the per-pound costs to write an equation . . .
5R+3.8P=121.5
Now just solve that first equation. . (R+P=30) for R. R= 30- P
now use that to substitute in the other equation
5R+3.8P=121.5
5(30-p) + 3.8P=121.5
solve for p
150- 5P+ 3.8p = 121.5
150-1.2p=121.5
150-1.2p=121.5
-1.2p=-28.5
P=23.75
now use that to find r
R+p =30
r+23.75=30
R=6.25
(hope this helps sorry it took so long to type )
have a good day !
