1) solve for x by multiplying each equation with the opposite number and making one a negative

-4(5x + 2y =-9)-4
5(4x +3y = 25)5

2) multiply on both sides of equal sign

-20x - 8y = 36
20x + 15y = 125

3) add all the like terms to get new equation

7y = 161

4) simplify

7y = 161
/7 /7

y = 23

5) make ordered pair and then input 23 into original equation

( x , 23)

5x + 2y = -9
5x + 2(23) = -9
5x + 46 = -9
-46 -46
5x = -55
/5 /5

x = -11

6) input to ordered pair

(-11, 23)

7) Thats your answer!

What would area B be and why?

Annette [7]

Answer:

B= y+2w

Step-by-step explanation:

We can see that A= y+3w, so because B is missing one of the w's, the area must be y+2w.

=. What does the expression (x+3)(9) represent? Why?

tresset_1 [31]

Because when you multiply the 9 by x you get 9x and when you multiply the 9 by 3 you get 27. So then your final answer would be 9x + 27.
I hope this helps!! :)

Need help on 20. Prove that a and b are parallel

Serjik [45]

a and b are parallel because 114 = 66+48 = 114, these two angles are the same because they are alternate exterior angles, and they couldn't be the same if a and b are not parallel.
