Answer:
x int (4,0)
y int (0, -6)
Step-by-step explanation:
Answer:
To decide whether to add or subtract, determine if the values of the coefficients are the same or opposites:
. If the values are the same, subtract the equations.
• If the values are opposites or additive inverses, add the equations.
Step-by-step explanation:
Given
Required
How to solve
Options (1) and (2) are incorrect because none of the options eliminate x or y.
For option (3),
- Check for the coefficients of x and y
- If they are the same (sign and value), then subtract; otherwise add
For instance:
Rewrite the second equation
The coefficient of y are the same, so we subtract;
<em>See that y has been eliminated</em>
If u are looking for x its 4 because if y=2 then u substitue it for y and you get -x+2=-2. to get x by its self you have to subtract 2 from both sides and u end up with -x=-4 and u have to divide -x by -1 to get rid of the negative and u get x=4
Answer:
The average rate of change is -3
Step-by-step explanation:
we have
This is a linear function in slope intercept form
where
m is the slope
b is the y-intercept
In this problem
The slope is equal to
Remember that
In a linear function the average rate of chance is a constant and is equal to the slope of the linear function in any interval
therefore
The average rate of change is -3
