Answer:
465.988 mph
Step-by-step explanation:
The two speed vectors form two sides of a triangle. Their included angle is 45°, so the law of cosines can be used to find the resultant magnitude x.
x^2 = 500^2 +50^2 -2·500·50·cos(45°) ≈ 217,144.66
x ≈ √217,144.66 ≈ 465.988 . . . . miles per hour
_____
You may find you need to round the answer to the nearest whole number.

Y=5x-3
the slope is plus 5
so if 1 = 2
simply subtract 5 from two and you get -3
