Answer:

C infinitely many solutions

Step-by-step explanation:

multiply second equation by -3

-3 × (4x + 3y) = -12 ➡ -12x - 9y = 36 now add this to second equation

12x + 9y -12x -9y = -36 + 36 ➡0 = 0

we say there's infinite solutions because whatever value you write for x and/or y there will be a solution.

Lady_Fox [76]

Answer:

Step-by-step explanation:

Slope of the trail is expressed as;

Slope = vertical distance/horizontal distance

Given

Vertical distance = 60metres

Horizontal distance= 300metres

Substitute

Slope = 60/300

Slope = 6×10/30×10

Slope = 6/30

Slope = 6×1/6×5

Slope = 1/5

Hence the slope of the trail in reduced fraction is 1/5
