Answer:

if f(x)= -4x+3

f(-5)= 23

Step-by-step explanation:

first you substitute x for -5

f(-5)= -4(-5)+3

then you multiply

-4(-5)

f(-5)=20+3

you get the positive 20 because negative times negative equals positive

then you just add the rest (20+3) which will give you your answer

f(-5)= 23

For this case we have the following function:
f (x) = (1/3) * (4 ^ x)
We must evaluate the function for x = 2
We have then:
f (2) = (1/3) * (4 ^ 2)
Rewriting:
f (2) = (1/3) * (16)
f (2) = 16/3
Answer:
The function evaluated at x = 2 is:
f (2) = 16/3
option A

Subtracting from a negative number is the same thing as adding. If you have a negative number and you have to subtract from it. You just add both of the negative numbers together.

How can addition properties help me add whole numbers

Bas_tet [7]

Answer:

There are four addition properties that help to add whole numbers :

For any whole number a, b, and c ;

1. Closure property of addition - $a+b$

For example:

2+3=5

4+3=7

We can conclude that if we add any two whole number , we get another whole number.

2. Associative property of addition- when any whole number or variable are added, then that can be grouped in different way without changing result

$a+(b+c)=(a+b)+c$
