Find the linear function. f(x)=-9+8 the inverse for the linear function is f^-1(x)=

1 answer:

8 0

I'm assuming there is supposed to be a x next to the -9. If that is the case, the inverse is:

f(x) = (x - 8)/-9

You can find this by switching the x and f(x) values and then solving for the new f(x) value.

x=-9f(x)+8 ---> subtract 8 from both sides
x - 8 = 9f(x) ----> divide both by -9
(x - 8)/-9 = f(x)

Answer:

#1. 31.4 square units

Step-by-step explanation:

We are solving for the square units and also we are circumference formular

which is C = R x 2) (3.14)

R is 5 but in a case they don't give us the Radius and gives us the Diameter we decide the Diameter by 2 and we will get the radius.

Back to the problem

C = R x 2) (3.14)

C = 5 x 2 x 3.14

C = 10 x 3.14

C = 31.4

$To \; find \; the \; maximum \; number \; of \; items \; possible \; in each \; packet,\\we \; need \; to \; find \; the \; Greatest \; Common \; Factor\\ \; of \; 527 \; Pencils, \; 646 \; erasers \; and \; 748 \; sharpeners.\\\\We \; need \; to \; list \; the \; Factors \; of \; each \; number \; as \; given \; below\\ \; and \; identify \; the \; greatest \; common \; factor.$

$The \; factors \; of \; 527 \; are:\\1, \; 17, \; 31, \; 527\\\\The \; factors \; of \; 646 \; are:\\1, \; 2, \; 17, \; 19, \; 34, \; 38, \; 323, \; 646\\\\The \; factors \; of \; 748 \; are:\\1, \; 2, \; 4, \; 11, \; 17, \; 22, \; 34, \; 44, \; 68, \; 187, \; 374, \; 748\\\\Then \; the \; greatest \; common \; factor \; is \; 17.$

$Conclusion: \\There \; will \; 31 \; Pencils, \; 38 \; Erasers,\\ \; and \; 44 \; Sharpeners \; in \; each \; of \; SEVENTEEN \; packet.$
