given the equation 3x − 4y = 8, which equation below would cause a consistent-dependent system? 3x 4y = −8 6x − 8y = 12 9x − 12y = 24 16x 12y = −10
If you would like to know which equation would cause a consistent-dependent system, you can find this using the following steps:
3x - 4y = 8 /3
3 3x - 3 4y = 3 8
9x - 12y = 24
The correct result would be 9x - 12y = 24.
Answer:
Equation (c) 9x - 12y = 24 would cause a consistent-dependent system
Step-by-step explanation:
Given equation 3x − 4y = 8
We have to find the equation from the given option that would cause a consistent-dependent system.
A given system of linear equation \(a_1x+b_1y+c=0 \ and\ a_2x+b_2y+c_2=0\)
If a consistent system has an infinite number of solutions, it is dependent . When you graph the equations, both equations represent the same line that is slope of both the equation will be same.
that is possible when \(a_2\) is multiple of \(a_1\) and \(b_2\) is multiple of \(b_1\) and this multiplication factor is same for both.
Thus, for the given equation 3x − 4y = 8
Only equation (c) 9x - 12y = 24 is a multiple of equation 3x − 4y = 8 with same factor of multiplication 3
Also, the slope of two equation is same \(\frac{3}{4}\)
Thus, equation (c) 9x - 12y = 24 would cause a consistent-dependent system
