Analyzing a Linear Combination of a System of Equations
The linear combination method is applied to a system of What does 0 = 0 indicate about the solutions of the
equations:
system?
1. (4x + 10y = 12)
There are 0 solutions to the system.
(10x + 25y = 30) -
The solution to the system is (0,0).
There are solutions to the system at the x- and y-
2. 2x + 5y = 6
intercepts.
-2x - 5y = -6
There are infinitely many solutions to the system.
3.0 = 0

Find the value of x in each case. give reasons to justify your solutions! d q ∈ pr

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14

If the car had not hit the fence, how much farther would it have skidded? solve the skid-distance formula to find the extra distance that the car would have traveled if it had not hit the fence. round your answer to two decimal places. note that unit conversion is built into the skid distance formula, so no unit conversions are needed.
