In the process of solving rational cquations, we may obtain _
extraneous solution
it is NECESSARY TO CHECK the solutions obtained if it will satisfy the equation or not. true or false
true
In some cases, a rational equation DO NOT have a solution. true or false
true
If the Rational Equation contains SUM or DIFFRENCE of rational expressions we can multiply by the LCM to remove the fractions, then solve for the value of variable algebraically. true or false
true
If both sides of the equation is a single rational expression we can just cross-multiply, then solve for the value of variable algebraically. true or false
true
The x and y axes, divides the plane into 4 QUADRANTS. true or false
true
The x coordinate or abscissa indicates the horizontal distance to the right or left of the y-axis. true or false
true
The y coordinate or ordinate indicates the directed distance of that point from the x- axis. true or false
true
if the point lies on the 1st quadrant, both of the coordinates have a positive sign. true or false
true
if the point lies on the 2nd quadrant, the x coordinate is negative and the y coordinate is positive. true or false
true
if the point lies on the 3rd quadrant, both of the coordinates have a negative sign. true or false
true
if the point lies on the 4th quadrant, the x coordinate is positive and the y coordinate is negative. true or false
true
if there is a 0 in any of the coordinate, the point will just lie along one of the axes. true or false
true
All Functions are Relations but not all relations are functions. true or false
