The terms are (4.2x), (-3.9), (-5.1x), (6)

like terms are terms that represent the same variable.

-3.9 & 6 both do not represent any varibles, they are just numbers, so they are like terms

4.2x & -5.1x both represent (x) so they are like terms.

to collect like terms, you create a smaller equation, just for them.
so you equations are;
-3.9+6
&
4.2x-5.1x

note: you know to add the 6 as all positive numbers have a + infront, it is just not written.

-3.9+6=2.1
4.2x-5.1x=-1.1x

therefore your equation after collecting like terms is 2.1-1.1x.

Hope this helps :)

You drive from your home to a vacation resort 420 miles away. You return on the same highway. The average velocity on the return
attashe74 [19]
<h2>Time required to complete the round​ trip T=\frac{420}{x}+\frac{420}{(x-15)} where x is average velocity on the outgoing​ trip.</h2>

Step-by-step explanation:

Let average velocity of outgoing trip = x mph

The average velocity on the return trip is 15 miles per hour slower than the average velocity on the outgoing trip.

Average velocity of return trip = (x-15) mph

Distance to vacation place = 420 miles

Distance to vacation place = Time for outgoing trip x average velocity of outgoing trip

          420=t_1\times x\\\\t_1=\frac{420}{x}

Distance to vacation place = Time for return trip x average velocity of return trip

          420=t_2\times (x-15)\\\\t_2=\frac{420}{(x-15)}  

We have total time T = t₁ + t₂

That is

                     T=\frac{420}{x}+\frac{420}{(x-15)}

Time required to complete the round​ trip T=\frac{420}{x}+\frac{420}{(x-15)} where x is average velocity on the outgoing​ trip.

Which is not an agency under the direction of the Department of Homeland Security?
fredd [130]
The Federal Bureau of Investigation is not an agency under the direction of the Department of Homeland Security. The correct option among all the options that are given in the question is the third option or option "c". FBI is actually the domestic intelligence and security agency. I hope the answer comes to your help.
