Solve the system of linear equations by graphing. x - 4y = -4 -3x – 4y = 12
1 answer:
Answer:
We conclude that the solution to the system of linear equations will be:
(x, y) = (-4, 0)
Step-by-step explanation:
Please check the attached diagram.
In the attached diagram:
- The red line represents the line x - 4y = -4
- The blue line represents the line -3x – 4y = 12
From the diagram, we can easily identify that both lines meet or intersect at x = -4 and y = 0.
In other words, the point of intersection of the system of equations is:
(x, y) = (-4, 0)
We know that the point(s) of the intersection of the system of equations represents the solution of the system of equations.
Therefore, we conclude that the solution to the system of linear equations will be:
(x, y) = (-4, 0)

Answer:
The intercepts
Step-by-step explanation:
Given:
Required
Determine the intercepts
The equation is a linear equation and the intercepts of the equation is calculated as thus;
For x intercepts; substitute 0 for y
Add 1 to both sides
Divide both sides by 4
Simplify fraction to lowest term
For y intercept, substitute 0 for x
Subtract 5 from both sides
Divide both sides by 3
Reorder
Hence, the intercepts
Answer:
D)
Step-by-step explanation:
Given expression:
The above expression can be rewritten using grouping symbols by using properties of equality.
We apply distributive property of multiplication according to which:
the product of a number and each addend individually added together is equal to the product of that number and sum of the addends.
So, we can write
