Answer:
- simplifies to -2x -17 = 5x -10
- x = -1 . . . . the solution
Step-by-step explanation:
-2(x+5)-7=3x+2(x-5) . . . . starting equation
-2x -10 -7 = 3x +2x -10 . . . eliminate parentheses using the distributive property
-2x -17 = 5x -10 . . . . . . . . . collect terms
-7 -2x = 5x . . . . . . . . . . . . . add 10
-7 = 7x . . . . . . . . . . . . . . . . . add 2x
-1 = x . . . . . . . . . . . . . . . . . . . divide by 7
Answer:
B
Step-by-step explanation:
Answer:
The following lines is perpendicular, y=-x+6 and y=x+1
Step-by-step explanation:
- Slope of parallel lines are equal
(ex. slope of 2 stays 2 )
- Slope of perpendicular lines to another is the negative reciprocal
(ex. slope of 2 becomes -1/2)
y = -x + 6 and y = x + 1
the slope for y = -x + 6 is <em>-1 (-1/1)</em>
the slope for y = x + 1 is <em>1</em>
the slope -1 is the negative reciprocal of 1
hence, the definition of perpendicular fits the given
