y + 3 = 
(x - 5)
the equation of a line in point- slope form is
y - b = m ( x - a )
where m is the slope and (a, b) a point on the line
here m = and (a,b) = (5 , - 3 )
y + 3 = (x - 5 ) ← in point-slope form
Answer: x = 9.611 ; or ; x = 9 11/18 .
_________________________________________________
Explanation:
________________________________________________
All angles of any triangle must add up to 180 degrees.
So, (10x - 4) + (8x + 3) + 91 = 180 ; Solve for "x" ;
___________________________________________
10x - 4 + 8x + 3 + 81 = 180 ;
Combine the "like terms" on the left-hand side of the equation:
___________________________________________
+10x + 8x = 18x ;
- 4 + 3 + 8 = 7 ;
____________________________
18x + 7 = 180 ;
___________________________________________
Subtract "7" from each side of the equation:
___________________________________________
18x + 7 - 7 = 180 - 7 ;
___________________________________________
to get:
18x = 173 ;
_________________________________
Divide EACH side of the equation by "18" ; to isolate "x" on one side of the equation; and to solve for "x" ;
_________________________________
18x / 18 = 173 / 18 ;
_________________________________
x = 9.6111111111111111....
_____________________________________
Write as: 9.611 ; or; 9 11/18.
____________________________________
The answer is 9 3/7 the last one
