Line A is 3x+y=12 and line B is y=4x-2 what changes can be made to make lines A and B perpendicular? WHATS THE ANSWER

9514 1404 393

Step-by-step explanation:

This is a rather open-ended question with an infinite number of possible answers. Here, we have elected to make a change in one coefficient in one of the equations to make its line perpendicular to the other line.

The change to Line A that makes it perpendicular to B results in an equation that is not in standard form. To put the equation into standard form would require another change to that equation.

__

The slope of line A is -3, so a perpendicular line will have a slope of 1/3. The coefficient of x in Line B can be changed to 1/3 to make it perpendicular to A.

__

The slope of line B is 4, so a perpendicular line will have a slope of -1/4. The coefficient of y in Line A can be changed to +12 to make it perpendicular to B.

Additional comment

If your original question has possible answer choices, you need to determine which choice will make the lines perpendicular. When lines are perpendicular, their slopes are opposite reciprocals of each other. The slope is the coefficient of x when the equation is solved for y.

answer: haha (: i’ll go see what it is

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas
