Answer:
x = 14 and x = - 7
Step-by-step explanation:
Not that + (- ) = -
(a)
x + (- 4) = 10, that is
x - 4 = 10 ( add 4 to both sides )
x = 14
(b)
2x - 10 = - 24 ( add 10 to both sides )
2x = - 14 ( divide both sides by 2 )
x = - 7

Answer:
y =
+ 2
Step-by-step explanation:
The slope of the line that has an x intercept of (2,0) and y-intercept of (0,-6) is:
Slope(s) = Change in y ÷ change in x
s =
= 3
The slope of the perpendicular line to this line with slope of 3 has to have a slope of -1 ÷ 3 = 
Reason: The product of slopes of lines perpendicular to each other have to be -1
So the slope of the perpendicular line that passes through (-6,4) is 
As mentioned earlier, we derive a slope of a line by dividing the change in y by the change in x
Taking another point (x,y) on the line,
= 
= 
y - 4 =
x - 2
y =
x + 2
