ludmilkaskok [199]

Hey!

-------------------------------------------------

This just shows to substitute all of x with -1.

g(-1) = 3(-1) - 5

g(-1) = -3 - 5

g(-1) = -8

Hence, the answer is -8!

Hope This Helped! Good Luck!

Divide 1/2 and 3/4 and it can not be a mixed number.
mamaluj [8]

Answer:

Many options - 4/6 or 2/3 or 0.66

Step-by-step explanation:

When dividing fractions, we use KCF (keep, change, flip) so our new equation is 1/2 x 4/3. Just multiply! Your answer should be 4/6, and if it needs to be simplified, the answer is 2/3. The answer as a decimal is 0.66 !
