Answer:

6x+1

Step-by-step explanation:

Hi there!

We are given the following expression:
4x + 8 + 2x - 7

And we want to simplify

When we simplify, we want to combine like terms. This means that we want to add terms with the same variables together (like x), and then combine them  

If there is no variable, then we add and combine the terms that don't have any variable together as well

Please note that we cannot combine terms with different variables (so if you had x+y, then it would stay as x+y).

In this case, we have 4x + 8 + 2x - 7

4x and 2x are like terms; they have the same variable (x). If we add them together, the result is 6x

8 and -7 are also like terms; they both don't have a variable. If we add (or rather, subtract) these terms, the result is 1.

Now we add 6x and 1 together, which would be 6x+1 (1 doesn't have a variable after it, so we can't combine it with 6x).

6x+1 is our answer.

Hope this helps!

Prove that A is in the subset B if P(A) is in the subset P(B)
natima [27]
Show that if p(a) ⊂ p(b) then a ⊂ b. 

<span>I will assume p() means power set. </span>

<span>proof: let x∈a, then {x} ∈ p(a) and so by hypothesis {x} ∈ p(b). However {x} could not be in p(b) unless x∈b. This shows that each element of a is an element of b and hence a ⊂ b.

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

Triangles triangle ABC and triangle DEF are similar. Find the angles of these triangles if Mesurements of angle A=100 degrees, a
beks73 [17]

Answer:

<D = 100

<E =30

<F =50

Step-by-step explanation

Given that triangles triangle ABC and triangle DEF are similar, this means that their angles are congruent i.e

<A = <D

<B = <E

<C = <F

Given

<A = 100 then <D = 100

<B = 30°, then <E = 30°

To get <F, we will use the expression

<D+<E+<F = 180 (sum of angles in a triangle is 180°)

100+30+<F = 180

130+<F = 180

<F = 180-130

<F = 50°

Hence the measure of <F is 50°

Find the approximate location of 2/3, 1/2, and 3/8 on a number line 0 to 1
schepotkina [342]

Answer:

0.6 (terminating), 0.5, 0.375

Step-by-step explanation:

I would assume you are wanting these in decimal form. In that case, you would have:

2/3 = 0.6 (terminating)

1/2 =  0.5

3/8 = 0.375
