Answer:
y = -2x+5
Step-by-step explanation:
The formula for slope is y=mx+b.
(m = slope and b = y-intercept)
Plug in the numbers and you get your equation.
Answer:
let jolene's dvd be x
2x+x+3x= total dvds = 6x
2x/6x=1/3
Salena has 1/3 of the total dvds
Answer:
-3.2a-35b+4.8c
Step-by-step explanation:
It might be wrong but this is how i solved it: i used the elimination method to solve this and got x is 3-4y and y is all real numbers
first multiply the top equation by 5 and then you get:
5x+20y=15
-5x-20x=-15
since all the numbers are canceled out it is all real numbers.
then for x since you can’t substitute the y back in i just did:
x=3-4y
i just moved over the 4y
and to prove it you can say you substituted several points and they all worked
hope this helped let me know if you have any questions
