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

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 <span>9x - 12y = 24.</span>

Answer:

If you move the decimal point the same number of places in the dividend and the divisor, you are multiplying them both by the same power of 10. That does not change the quotient

Mumz [18]

Answer:

863-7=856, 870-30=840, 900-55=845

Step-by-step explanation:

I think this may be the answer that is if you are to change the equations to subtraction problems, I can't see the picture so it's hard to answer.

Have a great day!
