Answer:
<h2>In the attachment.</h2>Step-by-step explanation:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept → (0, b)
We have m = -1 and b = 3. Substitute:
The graph is a straight line. Therefore we need only two points to plotting the graph.
One we have, the y-intercept (0, 3). Calculate other point.
Put any value of x to the equation of a line and calculate the value of y:
For x = 3:
Answer:
The solutions for both system of equations are as follows:
Step-by-step explanation:
The first set of equations is:
It can clearly be seen that the coefficients of y are already same in magnitude with different signs so we have to add both equations
So adding both equations, we get
Putting x=5 in equation 1
The solution is (5,2)
The second set of simultaneous equations is:
We can see that the coefficients of x in both equations are same in magnitude with opposite signs so
Adding both equations
Putting y= -1 in first equation
The solution is: (2,-1)
Hence,
The solutions for both system of equations are as follows:
Answer:
4y
Step-by-step explanation:
every part of the equation can be evenly divided by 4 and y
so this leaves you with 4y (-4 + 3y - 1)
