Answer:
(0,-9) You have to substitute 0 for x and solve for y
Answer:
The inverse is 1/2x +4
Step-by-step explanation:
g(x)=2x -8
y = 2x-8
Exchange x and y
x = 2y-8
Solve for y
x+8 = 2y-8+8
x+8 = 2y
Divide by 2
1/2 x + 8/2 = 2y/2
1/2x +4 = y
The inverse is 1/2x +4
Answer:
The estimated amount earned by band each day is $107.
Step-by-step explanation:
Let the amount Hey band earned each night = $k
Now, the band played for 3 nights.
So, the amount earned in 3 days = 3 x ( amount earned each day)
= 3 x $k = $3k
Also, the band earned an amount of $321 in 3 days.
⇒$3k = $321
or, k = 321/3
⇒ k = 107
Hence the estimated amount earned by band each day is $107.
Let the speed of first car be x mph
the speed of the second one is (x+3) mph
Relative speed=x+x+3=(2x+3) mph
but
time=distance/speed
thus
3=(261)/(2x+3)
solving for x we get:
3(2x+3)=261
6x+9=261
6x=261-9
6x=252
hence:
x=42 mph
Thus the average speed of first car is 42 mph
Average speed of the second car is (42+3)=45 mph
