Answer:

-5

Step-by-step explanation:

f(-2) means that -2 is going to be our input in this function.

To solve this, simply substitute -2 for x in the expression given.

If f(x) = 3x+1, then f(-2) = 3(-2) + 1

3(-2)+1 = -6+1 = -5

Hope this helped!

Joan and amber have a combined age of 34. If amber is 2 years less than twice Joan's age, how old is each girl?

Illusion [34]

Joan: 12 years old
Amber: 22 years old

If Amber is 2 years less than twice the age of Joan that means that Joan's age (12) times 2 (=24), minus 2 (=22) gives u Amber's age. Also when the two ages are added 12+22 they equal 34
Hope this helps! :)

Consider a bag containing four red marbles, three green ones, one transparent one, three yellow ones, and three orange ones.

Allisa [31]

Answer:

Step-by-step explanation:

Given,

Number of red marble = 4
number of green marble = 3
number of transparent marble = 1
number of yellow marble = 3
number of orange marble = 3

Total number of marble except red and green = 3 +3+1

= 7

So, the total number of possible sets of five marbles such that none of them are green or red can be given by

$n\ =\ ^7C_5$

$=\ \dfrac{7!}{(7-5)!.5!}$

$=\ \dfrac{7!}{5!.2!}$

$=\ \dfrac{42}{2}$

= 21

So, the required number of possible sets are 21.
