Answer:
Step-by-step explanation:
y intercept is -3
x intercept is 4
Answer:
y+2=-1/3(x-1)
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-1-(-2))/(-2-1)
m=(-1+2)/-3
m=1/-3
m=-1/3
y-y1=m(x-x1)
y-(-2)=-1/3(x-1)
y+2=-1/3(x-1)
X+Y=8 »» X=8-Y
now we can substitute X with 8-Y in the second equation, which was X-Y=2
X-Y=2 »» (8-Y)-Y=2 »» 8-2Y=2 »» 2Y=8-2 »» Y=6/2 »» Y=3
since X=8-Y, and Y=3, so X=8-3=5
X=5 and Y=3
Answer:
<h2>n = - 8</h2>
Step-by-step explanation:
![4(n + 5) = 4 + 2n](https://tex.z-dn.net/?f=4%28n%20%2B%205%29%20%3D%204%20%2B%202n)
<u>Expand the terms in the bracket</u>
That's
![4n + 20 = 4 + 2n](https://tex.z-dn.net/?f=4n%20%2B%2020%20%3D%204%20%2B%202n)
Subtract 2n from both sides of the equation
![4n - 2n + 20 = 4 + 2n - 2n \\ 2n + 20 = 4](https://tex.z-dn.net/?f=4n%20-%202n%20%2B%2020%20%3D%204%20%2B%202n%20-%202n%20%5C%5C%202n%20%2B%2020%20%3D%204)
Subtract 20 from both sides of the equation
![2n + 20 - 20 = 4 - 20 \\ 2n = - 16](https://tex.z-dn.net/?f=2n%20%2B%2020%20-%2020%20%3D%204%20-%2020%20%5C%5C%202n%20%3D%20%20-%2016)
<u>Divide both sides by 2</u>
![\frac{2n}{2} = - \frac{ 16}{2} \\](https://tex.z-dn.net/?f=%20%5Cfrac%7B2n%7D%7B2%7D%20%20%3D%20%20-%20%20%5Cfrac%7B%2016%7D%7B2%7D%20%20%5C%5C%20)
We have the final answer as
<h3>n = - 8</h3>
