Answer:
The solution to the system of equations be:
Step-by-step explanation:
Given the system of equations
4x-2y = 16
y = -5x+13
Solving the system of equations using the substitution method
Substitute y = -5x+13 in 4x-2y = 16
Now isolate x for
Add 26 to both sides
Simplify
Divide both sides by 14
Simplify
For y = -5x+13
Substitute x = 3
Simplify
Therefore, the solution to the system of equations be:
You start by adding up all the socks, so 12+8=20 then you set up the ratio 8/20 and you simplify it, and the gcm is 4 so you would divide each by 4 which would give you a 2/5 ratio which is option "A"! hope this helps!
11 liters of 25% orange juice, 4 liters of 10% orange juice:
1' let x to be 25% orange juice and y be 10% orange juice
2' .25x+.10y=(15).21
3' x+y=15
4' 2.5x+y=31.5 divide all sides by 10
5' -x-y=-15 multiply all sides by -1
6' 1.5x=16.5
7' x=11
8' y=15-11=4
so 11 and 4 are the answers.
I would say:
<span>The initial values of the two functions are different, and the rates of change of the two functions are the same.

5x + 9+x = 9x
x=3
