Hi, ok all you need to do is use the direct variation formula which is= y/x=y/x so you will replace your numbers by each value which get us to = 3/-6=y/1 so you cross multiply which gives us 3=-6y you divide 3 by -6 and that is the value of y, thank you for reading hope it helps ;)
5x+3y=58
5x-3y=22
(3y gets cancelled bc 3y-3y=0, then add 5x with 5x, so you're left with)
10x=80, (divide both sides by 10)
x=8
Now we look for y. So choose one formula from the two (let's say 5x + 3y=58)
Substitute x for 8 so it will look like---- 5(8)+3y=58
Multiply 5*8--- so you get -- 40+3y=58
Subtract 40 from both sides and you're left with 3y=18
divide both sides by 3
you get y=6
In conclusion, x=8 and y=6 hence, (8,6)
Answer:
300-20x<100
Step-by-step explanation:
More than, is like greater than, making it a greater than sign,
$100 is the number that is being compared to the other two, so it goes on the other side
$300 is the inital price, so it has no variable
Last, the $20 represents the cost per shirt giving it an unknown variable
I hope this helps u
pls give a brainliest and a thx ;)
Repost your question. Unclear as typed.
Top 1. Substitute 3y on both sides of the equation.
Bottom 2. Substitute 2y on both sides of the equation
3y and 2y cancel
Divide x by 4 and 26 by 4.
Is there die points on a graph or decimal?
I have not done this for years but there is many calculators that can show you step by step online. I recommend using these
