Answer:
1
Step-by-step explanation:
Answer:
The graph is shifted 1 unit right
The graph is shifted 2 units down
Step-by-step explanation:
We are given
Parent function as
New function as
we can also write as
We can see that
1 is subtracted to x-value
and 2 is added to y-value
So, f(x) is shifted right by 1 unit
and
f(x) is shifted up by 2 unit
Answer:
A
Step-by-step explanation:
Slope intercept form is y = mx + b
First find the slope or m with this equation (plug in) = =
So your slope is
To find the y-intercept you use y= mx + b and plug in.
6 = 1/4(12) + b
6 = 3 + b (minus 3 on both sides)
3 = b
so 3 is the y-intercept
So the answer is A.
Let airspeed of the plane be x mph and wind speed = y mph. Then we have the following system of equations
x - y = 1160 / 4.833 = 240.0166
and
x + y = 1160 / 4 = 290
adding the 2 equations:-
2x = 530.0166
x = 265 mph = airspeed of the plane
y = 290 - 265 = 25 mph = speed of the wind
