3 0

Answer:

im not the best at algebra but

2a+3b+4c

Step-by-step explanation:

subtract

(2a−3b+4c) from the sum of (a+3b−4c),(4a−b+9c) and (−2b+3c−a).

add

=(a+3b−4c)+(4a−b+9c)+(−2b+3c−a)

=(a+4a−a)+(3b−b−2b)+(−4c+9c+3c)

=4a+8c

then subtract

=(4a+8c)−(2a−3b+4c)

=4a+8c−2a+3b−4c

=2a+3b+4c

Identify the type of function represented by f(x)=3(1.5)^x
Murljashka [212]
Here your base (1.5) is greater than zero, so you have exponential growth here.  That " ^ " is the tip-off to exponentiation.

__ x 5 &gt; 5 <br><br> 3/3 <br> 2/3<br> 5/3
Citrus2011 [14]
_ * 5 > 5

3/3 is equal to 1 which would make them equal to each other.
2/3 is less than one which means it would make the number on the left less than 5, not greater than.
the answer is 5/3 because it is bigger than the other answer choices and will result in a greater number than that on the right.
