Answer:
f(3) = 7
Step-by-step explanation:
Substitute x = 3 into f(x) , that is
f(3) = 4(3) - 5 = 12 - 5 = 7
5 2/3 - 1 1/4
5-2 =3
2/3 - 1/4 = 8/12 - 3/12 = 5/12
answer is 3 5/12
A.450.80
Multiply 40x9.80=392
Take 1/2 of 9.80 that equal 4.90
4.90 plus 9.80 $14.70x4=58.80
$58.80 plus 392 equals 450.80
