No association because the dots are just scattered all over the graph
Negative association would be when the dots are going toward downwards
Positive association would be when the dots are going toward upwards
5(2y + 7) = 20
5(2y) + 5(7) = 20
10y + 35 = 20
<u> -35 -35</u>
<u>10y</u> = <u>-15</u>
10 10
y = -1 1/2
To solve this system of linear equations we need a little trick called elimination steps are below
we are given the following system of equations


if you look at the x variables in both equations you can see that we can easily eliminate them by multiplying the bottom equation by -4 as so


simplify and we get


now we can combine like terms on each side with the x's cancelling and get

now divide off -35

great now we can go back to our original system and pick a equation and substitute y back in to find x lets use

so now we substitute y and get




now we put x and y into one coordinate (x,y)
so now our FINAL ANSWER IS
(-17,-1)
Answer:
x > 5
Step-by-step explanation:
isolate x by subtracting 7 from both sides
x > 12 - 7
x > 5
Answer:

Step-by-step explanation:
Let
be the number of bags with 8 onions and let
be the number of bags with 3 onions. We have the following system of equations:

Subtracting
from both sides of the first equation, we get
. Substitute this into the second equation:

Therefore, the number of 8-onion bags is:

Thus, the chef got 4 8-onion bags and 3 3-onion bags.
