Answer:

See below.

Step-by-step explanation:

Part A:

The two lines have the same slope and different y-intercepts. The graphs of the two equations are parallel lines, so there is no solution.

Part B:

The two lines are really the same line with the same slope and y-intercept. Therefore every point on the line is a solution. There is an infinite number of solutions.

Part C.

The two lines have different slopes, so they intersect at a single point. Therefore, there is one solution.

What is -9x-(2x/-3) When x equals 7

yuradex [85]

$-9x- \frac{2x}{-3}$

$-9*(7) - \frac{2*7}{-3}$

$9*7 = 63$

$\frac{2*7}{-3} = \frac{14}{-3}$

Apply the fraction rule : $\frac{a}{-b} = - \frac{a}{b}$

$= - \frac{14}{3}$

$-63-( -\frac{14}{3} )$

Apply rule - ( - a) = a

$-63+ \frac{14}{3}$

Convert element to fraction :

$63 = \frac{63}{1}$

$-\frac{63}{1} + \frac{14}{3}$

Find the LCD 1*3 = 3

$- \frac{63*3}{3}+ \frac{14}{3}$

$\frac{-3+63+14}{3} = \frac{-175}{3}$

Apply the fraction rule : $\frac{a}{-b} = - \frac{a}{b}$ 

$= - \frac{175}{3}$
