54 = 3x + 37.5 <== ur equation....and x = number of years
54 - 37.5 = 3x
16.5 = 3x
16.5 / 3 = x
5.5 = x......so it would take 5.5 years...or 5 1/2 years <=

Is the equation parallel perpendicular or neither ? y = 5/4 x+1 and y = 5/4 x-7

weeeeeb [17]

Answer:

Parallel

Step-by-step explanation:

The equation of a line in slope - intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Both given equations are in this form, that is

y = $\frac{5}{4}$ x + 1 → m = $\frac{5}{4}$

y = $\frac{5}{4}$ x - 7 → m = $\frac{5}{4}$

Parallel lines have equal slopes thus the lines are parallel
