Answer:
Second triangle pair
Step-by-step explanation:
In a reflection, the shape is flipped. In the first pair, the corresponding sides as shown by the lines, and the corresponding angle are already in the same position. In the second pair, Δ MLN can be reflected so that line LN match with EG and line LM matches with line EF. ∠L and ∠E will also be mapped to each other when one triangle is reflected.

Answer:
Step-by-step explanation:
concentration = amount of salt/solution
A) Initial concentration= 90/1000 = 0.09
Q = quantity of salt
Q(0) = 90 kg
Inflow rate = 8 l/min
Outflow rate = 8 l/min
Solution = 1000 L at any time t.
Salt inflow = 0.045 * 8 per minute
= 0.36 kg per minute
This is mixed and drains from the tank.
Outflow = 
Thus rate of change of salt
Q'(t) = inflow - outflow = 
Separate the variables and integrate

Use the fact that Q(0) = 90
90 = 360-A
A = 270
So

B) Q(t) = 360-270e^-0.004 = 91.07784
C) When t approaches infinity, we get
Q(t) tends to 360
So concentration =360/1000 = 0.36
Number line graph with closed circle on 120 and shading to the right.
Since they need $150 in total and they already have $30 that means they need $120 or more to complete their $150. That means x = the amount of money they still need has to be greater than or equal to $120. The equation should be x >/= $120. Since a close circle means greater than or equal to and it matches that equation it means it that one. Also the circle has to be on 120 because it that the starting point of the amount they still need. And since they can get 120 or more it points to the right side.
