Replace x with each value then solve:
f(3) = 2(3) +1 = 7
f(0) = 2(0) +1 = 1
f(2) = 2(2) +1 = 5
f(1) = 2(1) + 1 = 3
Now you have:
7 -1 / 5 -3 = 6/2 = 3
1.5ft to inches = 0.125 inches
14×0.125×7= 12.25 inches cubed
The fence is a 8x4 fence as they multiply up to 32 square feet and 8 is double 4. If you add 8+8+4+4 you will get 24. Then you multiply the perimeter (24) by 3 to get the final cost. This means that the final cost will be $72.00.
-36x<8 divide both sides by -36 (reversing the direction of the inequality sign because of division by a negative number)
x>-8/36 the largest common factor of 8 and 36 is 4 so divide numerator and denominator by this factor, 8 to simplify the fraction
x>-2/9 or in proper notation, x=(-2/9, +oo)
Multiply 7 1/2 by 5 1/2 and get 41 and 1/4
now divide 41 1/4 by 1/2 and get 83..
83 would be your answer(I got a little confused so this might be wrong D:)
