Answer:
Step-by-step explanation:
x is the independent variable. y is the dependent variable.
Answer: 
Step-by-step explanation:
Remembert that, by definition:
→ 
Then, you can rewrite
in exponential form:

Now you can solve for the variable "x":
Add 6 to both sides of the equation:


And finally you must divide both sides of the equation by 2, then:

Answer:
The equation of the line is given as 2 y - x = 4.
Step-by-step explanation:
Here, the slope of the given line = 1/2
The point on the line is (x0,y0) = (6,5)
Now, by POINT SLOPE FORMULA:
The equation of line with (x0,y0) and slope m is written as:
(y - y0) = m (x-x0)
So, here the equation of line is given as

Hence the equation of the line is 2 y - x = 4.
Hey there! I'm happy to help!
Let's call our hamburgers h and our cheeseburgers c and set up a system of equations to solve.
c+h=512
c=3h
Let's plug this value of c into the first equation to solve for h.
3h+h=512
4h=512
Divide both sides by 4.
h=128
Therefore, 128 hamburgers were sold on Wednesday.
Have a wonderful day! :D
The commutative property of addition means that when you see a problem, you change the order. The co in commutative means change order. That's what my teacher told me.
