Answer:
n=1
Step-by-step explanation:
n+7n-5=3
8n=8
divide both side by coefficient of n we get
n=1
The unknown number is X;
x/6+2=9;
X/6=7;
X=42;
The answer is 42
(3x-5)(2x-7)
6x^2 - 21 x -10x +35
6x^2 -31x +35
The first one
Answer:
(13, -3)
Step-by-step explanation:
slope = -5/7
(6,2)
m = ( y2 - y1) / ( x2 - x1 )
-5/7 = ( y2 - 2) / ( x2 - 6 )
-5 = y2 -2
+2 +2
-3 = y2
7 = x2 - 6
+6 +6
13 = x2
Check answer again by log them in:
m = ( y2 - y1 ) / ( x2 - x1 )
m = ( -3 - 2 ) / ( 13 - 6 )
m = -5 / 7
I hope this helps!
