Step-by-step explanation:
3:5= 1.5:2.5
Each number is divided or multiplyed by the same number.
Ex. 3/2=1.5 and 5/2=2.5
Hope that helps idk if its right though lol
X = +12 in equation 9. Does that help?
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.
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.
