A system of linear equations is shown below, where A and B are real numbers. 3x + 4y = A Bx – 6y = 15 What values could A and B be for this system to have no solutions? A = 6, B = –4.5 A = –10, B = –4.5 A = –6, B = –3 A = 10, B = –3

Respuesta :

Answer:A=6 B=-4.5

Step-by-step explanation:

We want to find the values of A and B such that the given system of equations has no solutions. We will find that the values of A and B can be:

B = -4.5

A = 6

When a system of equations has no solutions?

A system of linear equations has no solutions when the lines are parallel (so the lines never do intercept).

Here the system is:

3x + 4y = A

Bx – 6y = 15

Remember that two lines are parallel if and only if they have the same slope and different y-intercept, then let's write both equations in the slope-intercept form:

y = A/4 - (3/4)*x

y = -15/6 + (B/6)*x

So we must have:

B/6 = -3/4

A/4 ≠ -15/6

From the first one we get:

B = (-3/4)*6 = -4.5

From the second one we get:

A  ≠ (-15/6)*4 = -10

Then from the given pairs, the only one that causes the system to have no solutions is:

B = -4.5

A = 6
