Answer: A) 2.5 km/ hour

You divide 10/4 and get 2.5, so 2.5km an hour.

B) 6.25 km/ hour

You have 2.5km/ hour plus 10km/ hour OVER 2. This would equal 12.5 km over 2

You then get 6.25 from doing 12.5/2

Match the graph to one of the exponential functions .
Ipatiy [6.2K]

Answer:

The second possible answer is the correct one.

Step-by-step explanation:

The second possible answer is the correct one.  As x increases, 4^x increases exponentially.  However, in this case there's a negative sign in front of 4^x, so we know that the graph follows an exponential trajectory downward.  Also note that 4^0 = 1, so 1 - 4^x = 0 at x = 0.

Solve the given system, using the substitution method.. . y = 3x – 4. 9x – 3y = 14. . . A.. There is no solution.. . B.. (12, 14
Gwar [14]
Y = 3x - 4 . . . (1)
9x - 3y = 14 . .(2)

Putting (1) into (2) gives
9x - 3(3x - 4) = 14
9x - 9x + 12 = 14
12 = 14

Therefore, there is no solution.
