Given: parallelogram QRST where QR equals 6X -5 and RS equals 4X +15, what value of X proves this parallelogram is a rhombus?

answer: b.

step-by-step explanation:

the y coordinate for point b is 0, and answer b is the only one with that y coordinate.

-60.75

step-by-step explanation:

just add the numbers then put the negative sign on it

b.

step-by-step explanation:

option a is correct.

only one solution to the system of equations

step-by-step explanation:

if the graph of the equations do not intersects(i.,e if they are parallel) then, there are no solutions that are true for both the equations.

if the graph of the equations intersects, then there is one solution and that is true for both the equations.

since, in the given figure:

the two lines intersect each other

⇒there is only one solution which satisfy both the lines of an equations.

therefore, there is only one solution to the system of equation
