Which expression represents the sum of (2x - 5y) and (x + y)?

3x-4y

Step-by-step explanation:

To express the sum of (2x-5y) and (x+y),

We are going to have

2x-5y+x+y

The next thing to do is to collect the like terms;

Then we have;

2x+x-5y+y

Answer realized will now be

3x-4y

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
