Answer:

-2a + 3b

Step-by-step explanation:

Since you need to simplify the expression, you need to combine like terms. 3a and -5a are like terms because they both have the variable a. 3a + -5a equals -2a. 2b + b equals 3b. Since b would equal 1. If you combine them together, you get -2a + 3b.

Hope this helps!!

Find the domain of the graphed function.
Burka [1]

The domain of the graphed function is x≥0.

<h3>What is domain of graph ?</h3>

The set of all input values of the graph is called domain of graph.

<h3>What is the required domain ?</h3>

We have to find the horizontal length of the graph, which is the length in x-axis.

In the given graph, the value of x starts from 0 and crossed the value 10

So, x=0 & x>10, which means all the positive values of x & x = 0 is the domain of this graph.

Hence, we can say that, x≥0 is the domain we want.
