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.

a boat going upstream at 4 mph then travels downstream at 10 mph. what is the rate of the boat in still water

elixir [45]

Answer:

7 mph

Step-by-step explanation:

If b is the rate of the boat, and s is the rate of the stream, then:

b − s = 4

b + s = 10

Solve the system of equations with substitution or elimination. Using elimination, add the equations together:

2b = 14

b = 7

The boat's rate is 7 mph.
