to inverse a equation make all y's x and andy x's y
Thus the inverse is
x=4y-8
Evaluated to
4y=x+8
y=
2.5 km because 1.5 is half of 3 and half of 5 is 2.5
1/12 is the square root of 1/144
15/4 simplifies to 3 1/2 and 17/5 simplifies to 3 2/5 so 15/4 is greater
All you have to do is look at the graph.
5 gallons of gas is $8.80, let’s figure out how much one gallon is. 8.80/5=$1.76.
1.76•6=10.56 check
1.76•7=12.32 check
Now let’s figure out how much 10 gallons of gas cost.
1.76•10=17.6
10 gallons of gas costs $17.60
