What statement is true about the relationship between the value of k and then number of solutions for the system of equations?A system of equations is shown below:3x - 2y = 79x - 6y = kA) For any value of k; the system of equations has no solution. B) For any value of k; the system of equations has infinitely many solutions. C) If k is equal to any value other than 21, the system of equations has no solutionD) If k is equal to any value other than 21, the system of equations has infinitely many solutions.

can i get the link to the assignment?

step-by-step explanation:

47 - 90 = 43

43 - 180 = x

x = 137

(2x + 16) + (x) = 180

step-by-step explanation:

given,

abcd is a quadrilateral inscribed in a circle

angle a is labeled x plus 16, (x + 16)

angle b is labeled x degrees, (x)

angle c is labeled 6x minus 4, (6x – 4)

angle d is labeled 2x plus 16, (2x + 16)

what equation can be used to solve for angle b?

we know that the sum of the opposite angles of a simple quadrilateral inscribed in a circle is 180 degrees.

angle b is opposite angle d

therefore, angle b + angle d = 180

(x) + (2x + 16) = 180 

same as (2x + 16) + (x) = 180
