Answer:
m = -1
Step-by-step explanation:
First write the line in slope intercept form y = mx+b where m is the slope and b is the y intercept
x-y = 6
subtract x from each side
-y = -x+6
Multiply each side by -1
y = x-6
The slope is 1
Perpendicular lines have slopes that multiply to -1
m * 1 = -1
m = -1
The slope of the perpendicular line is -1
Answer:
(4+5)3-8 = 19
Step-by-step explanation:
1) You know that the parenthesis are going to go around 3-8 or 4+5 because that is the only way multiplication is involved. If you put them anywhere else it doesn't change the answer.
2) Try solving the problems (use PEMDAS)
(4+5)3-8 = 9*3-8 = 27-8 = 19
4+5(3-8) = 4+5(-5) = 4-25 = -21
Actually those 4 angles are equal to 110 because those are vertical angles
Answer:x=-2/7
Step-by-step explanation:-2x squared = 4x+3x+2=0
7x+2=0
7x=-2
Divide both sides by 7 x= -2/7
