Hello :
<span>X - y = 4...(1)
x + y = 8...(2)
(1)+(2) :2x= 12
</span><span>The x-coordinate of the solution to the system shown is __6___.</span>
<u>Answer:</u>
The coefficient of 
<u>Solution:
</u>
The given expression is 
As per binomial theorem, we know,

Now here a = 2x, b = (- 3y) and n = 10 and k = 0,1,2,….10
Now
will be the 6 term where k =5
Now, 
So, the coefficient of
.

The coefficient of 
Answer:
<h3>

</h3>
Step-by-step explanation:
Let the points be A and B
A ( -5 , 1 ) ⇒( x₁ , y₁ )
B ( 2 , 4 )⇒( x₂ , y₂ )
<u>Findi</u><u>n</u><u>g</u><u> </u><u>the </u><u>slope</u><u> </u><u>of </u><u>the </u><u>line </u><u>passing </u><u>through</u><u> </u><u>these </u><u>Points</u>
Slope = 
plug the values
⇒
We know that 
⇒
Subtract 1 from 4
⇒
Add the numbers
⇒
Hope I helped!
