Answer:
b = 2 or b = 7
Step-by-step explanation:
b/(b-7) - 2/b = 7/ (b-7)
b * b - 2(b - 7) = 7 * b
b^2 - 2b + 14 = 7b
b^2 - 9b + 14 = 0
(b - 2)(b - 7) = 0
b - 2 = 0; b = 2
b - 7 = 0; b = 7
Answer
b = 2 or b = 7

To investigate which of the choices satisfy the equation, substitute the values of the abscissas into the equation and solve for y. See if the value of y calculated is equal to the value of the ordinate of the point.
A. (7, -2) ; (2)(7) + 5y = 4 ; y = -2 EQUAL
B. (0, -1) ; (2)(0) + 5y = 4 ; y = 0.8 NOT EQUAL
C. (0, 1) ; <span>(2)(0) + 5y = 4 ; y = 0.8 NOT EQUAL
D. (3, -2) ; (2)(3) + 5y = 4 ; y = -0.4 NOT EQUAL
Thus, the answer is letter A. </span>
