Answer:
A, C, and D
Step-by-step explanation:
Graph both equations on Desmos or a graphing utility. Make sure you have entered the inequality correctly. You see an area with both red and blue shaded. The area with both colors is where the solutions are. Looking at the graph, A, C and D are in the double shaded region.
Answer:
The correct answer is C.
Step-by-step explanation:
To find this, we need to note that in order to reverse the function of raising the b to the x power, we need to take the log base b of the function. Since the answer C is the only one containing that, it must be the correct answer,
Let the relative speed will be given by:
38/4=9.5 km/h
Let the speed of the first tourist be x km/h
the speed of the second one is (9.5-x) km/h
distance covered by the first one is:
4*x+2=4x+2 km
distance covered by the second one is:
(9.5-x)4 km
=(38+4x) km
total distance will be given by:
(38+4x)+(4x+2)=38
40+8x=38
8x=-2
x=-1/4 km/h
this mean that he was traveling in the opposite direct thus the speed was 1/4 km/k
The speed of the second one will be:
9.5-1/4=9.25 km/h
Answer:
No solution
Step-by-step explanation:
<u>The sides aren't equal so there will be no solution.</u>
