x-3+3 > 7+3
x > 10
Answer:
3
Step-by-step explanation:
The f^-1 notation indicates you need to find the inverse of the function
y=2x+1
x=2y+1
Exchange the x & y variables. Note this is what accomplishes that reflection across the line y = x
7=2y+1
-2y=1-7
-2y=-6
Divide both side of the equation by -2
negative divide negative is positive so
y=3

Answer:
A car is more fuel efficient and it goes 30 miles per gallon (5/12 gallon to travel 12 1/2 miles)
Step-by-step explanation:
A car : 5/12 gallon to travel 12 1/2 miles
(12 1/2) / (5/12) =
(25/2) / (5/12) =
25/2 * 12/5 =
150/5 =
30 miles per gallon
B car : 5/7 gallon to travel 20 5/7 miles
(20 5/7) / (5/7) =
(145/7) / (5/7) =
145/7 * 7/5 =
145/5 =
29 miles per gallon
most fuel efficient is A car....it gets 30 miles per gallon
