Yes it is. If you put 2/5 in the calculator it will come up as 0.4
Answer:
Step-by-step explanation:
The slope of g(x) is 5 because the slope of h(x) is 5 and g is parallel to h.
In point-slope form:
Rearranging for slope intercept form:
330 km/hr
Step-by-step explanation:
To find speed of the plane against the headwind;
600 km / 2 hours = 300 km/hr
Speed of plane with the wind in its back;
600 km / 5/3 hours = 600 * 3/5 = 360 km/hr
We can create a simultaneous equation from this data.
Assume the speed on pane in still air is x km/h
Assume the speed of wind is y km/h
Therefore;
x – y = 300
x + y = 360
Solving the simultaneous equation by elimination gives us;
x – y = 300
-
x + y = 360
=
-2y = - 60
y = 30
x = 330
The speed of the plane without wind is;
= 330 km/hr
The wind speed is;
= 30 km/hr

Answer: The y-intercept is 1
Step-by-step explanation:
y = mx + b m = slope, and b = y-intercept
plugging in the given values, we get
-9 = (-5/4)(8) + b
simplify to get
-9 = -10 + b
b = 1
y-intercept = 1
