Answer:
; 3
Step-by-step explanation:
In this question, we're being asked to write an equation using the word format. Let's find key words in the statement.
The <u>sum</u> of a <u>number x and 4</u>, <u>all divided by 3.</u>
<u></u>
Looking at the wording, we can conclude that we are adding x and 4, and dividing that by 3. So here's how the phrase would look as an expression.
(x+4) or 
Now, there's another part to this problem. We must evaluate the value of the expression if x is given to be 5. So let's plug it into our equations.
<u>(5)+4</u>
3

9/3 gives you 3, so your answer would be 3.

Answer:
2^(x-1) -5x +12
Step-by-step explanation:
f(x) = 2^(x-1) + 3
g(x) = 5x - 9
(f-g) (x) = 2^(x-1) + 3 - ( 5x-9)
Distribute the minus sign
2^(x-1) + 3 - 5x+9
Combine like terms
2^(x-1) -5x +12
A. If you divide 6 by 5, you will get 1.2 . So then if you add the 4/15 it will probably be 30 2/3. Because letter C. (31 1/3) seems like too much.
A - 3
Using the coordinates of the diameter, it is possible to figure out the radius.
Using the y axis, you can determine that 4 and -2 total to be six apart, leaving the diameter to be six. Knowing that the radius is half of the diameter, you can easily split the diameter in half to get the radius of 3.
Hope this helps!
