against wind the speed = x-y
distance traveled = 2460
2460/x-y= 6
6x-6y= 2460
x-y=410...........1
..
with wind speed = x+y
distance is same 2460
2460/x+y=5
5x+5y=2460
x+y=492............2
..
Add equation 1 & 2
x-y+x+y=410+492
2x=902
x= 451 mph speed of plane in still air.
..
Plug the value of x in equation 1
451-y=410
y=451-410
y=40 mph the speed of wind

Step-by-step explanation:
Answer:
D. the graph of g(x) is shifted 3 united left and 4 units up.
Step-by-step explanation:
When a change is made inside the parenthesis to the input, the function shifts left and right. Addition shifts it left while subtraction shifts it to the right. Here it is translated three units to the left. Adding or subtracting a number outside the parenthesis will slide the function up and down. Here it is shifted 4 units up.
Example: f(x) = x 
f(3) = 3 x+3 = 3
x+3-3 = 3-3
x=0 and f(0) = 0
So f(0) +4 = 0+4 =4

Step-by-step explanation:
Answer:
Step-by-step explanation:
If the measures of angles 1 and 2 are congruent, then the measures of 3 and 4 should also be congruent because they are vertical angles.
