Answer:
The answer is below
Step-by-step explanation:
A linear graph has an equation of the form:
y = mx + b,
where y and x are variables, m is the slope (rate of change) of the graph and b is the y intercept (value of y when x is 0).
Given that:
2x -2y = 4 , 3x + 2y = 6
The matrix form of the equation is:
AX = B
Answer:
4 cups of water per one cup of lemonade mix
Step-by-step explanation:
80 - 16 = 64
64/16=4
4 cups per cup
Not sure if I got the equations right but this is how I solved it:
Rearrange 6x-y=4 for y. Then since both equations equal y, you can set them equal to each other. From there solve for the y variable. To solve for x, plug in the new found y variable back into one of the original equations. Hope that helps
For this case we need the following skills:
Adding fractions // Subtracting fractions: necessary because operations with fractions need algebraic sum to clear unknowns.
Multiply fractions / Dividing fractions: Sometimes when doing common factor, you need to multiply and divide fractions.
Simplifying fractions: To rewrite the results, it is necessary to simplify fractions
Answer:
All mentioned skills are required.
