Answer:
Speed of Jet in Still Air = 265 miles per hour
Speed of Wind = 22 miles per hour
Step-by-step explanation:
Let x be speed of jet
and c be speed of wind
We know D = RT, where
D is distance
R is rate
T is time
For first leg:
1435 miles in 5 hours, the rate is:
Rate = 287 mph
For second leg:
1215 miles in 5 hours, the rate is:
Rate = 243 mph
So 287 is with wind and 243 against wind, thus we can write:
x + c = 287
x - c = 243
Adding gives us:
2x = 530
x = 265 miles per hour [still rate]
Speed of wind:
x + c = 287
265 + c = 287
c = 22 miles per hour [speed of wind]
(b-7)m=r
Use the distributive property to multiply b-7 by m.
bm-7m=r
Add 7m to both sides.
bm=r+7m
The equation is in standard form.
mb=7m+r
Divide both sides by m.
mb/m = 7m+r/m
Dividing by m undoes the multiplication by m.
b= 7m+r/m
Divide r+7m by m.
b= r/m+7
A. g(x)=(4x)^2
All you have to do is graph each equation and see what matches g(x) on the graph given.
Answer:
the dif is i would take the plus 9.5% each time cause you could always do over and get you salary even greater and it's better getting a plus then just the 450 every time
