Answer:
n =7
Step-by-step explanation:
(n+1) +1 + (n-1) = value first row
3+ (2n-9) +n = value second row
The value has to be the same
Set the equations equal
(n+1) +1 + (n-1) =3+ (2n-9) +n
Combine like terms
2n+1 = 3n-6
Subtract 2n from each side
2n+1-1 -2n = 3n-6-2n
1 = n-6
Add 6 to each side
1+6 = n-6+6
7 = n
Leave the x alone first. -2/5x<9/10+9. then -2/5×<99/10. multiply both sides by 5 you'll get -99/2 < 2x. then divide both sides by 2 you'll get -99/4 < ×

Answer:
<em>y = - 4x + 38 </em>
Step-by-step explanation:
A(3, 9)
B(5, 1)
= 
= - 4
CD║AB
C(9, 2)
y - 2 = - 4(x - 9)
<em>y = - 4x + 38</em>
