Answer:
the last one trust me i am basically a calculator when it comes to math which is 2 1/3 more gallons
Step-by-step explanation:
1 11/12
5 2/3 - 3 3/4
break off 1 from 5:
5 2/3 = 4 5/3
subtract the whole numbers:
4 - 3 = 1
find a common denominator so you can subtract the fractions, and multiply both the numerator and the denominator by the same number:
x 4 =
x 3 =
20/12 - 9/12 = 11/12
so your final answer is 1 11/12
i hope this helps! :)
9/56
Or did you mean:
f(x) = -x -1
f(x) = mx + b
find 2 points on the line:
A( -1 , 0)
B( 0 , -1)
Put them in the equation and fine m & b:
0=m(-1)+b
-1=m(0)+b
so b= -1
and m= -1
so f(x) = -x-1
