Answer:
3x - 2 = 10
Step-by-step explanation:
1/-3 or 4/-12, as long as you multiply or divide the numerator and the denominator with the same number the fraction will be equivalent. To get 1/-3 I divided 2 with 2 and -6 with 2.
Answer:
Idk
Step-by-step explanation:
Answer:
x=30
Step-by-step explanation:
So we know that a shape with 4 angles equal 360 degrees and this has 4 angles. Since we know that 4x is one and 2x is one We cna use the vertical angles to find the other two. Since 4x is opposite of an unknown side it is also 4x becuase vertical angles are equal becuase they are opposite sides of each other. Same thing with 2x
Now add them all up
4x+4x+2x+2x which will equal 12x
now 12x=360
x=30
Answer:
The lines are perpendicular.
Step-by-step explanation:
If the lines are parallel, then the slopes are equal
If the lines are perpendicular, then the slopes are negative reciprocals
If neither of the above occur, then the lines are neither parallel or perpendicular.
y = 2x + 3 is in slope-intercept form, so the slope = 2
2y + x = 6
Solve for y: 2y = -x + 6
y = -1/2(x) + 3 so the slope = -1/2
2 and -1/2 are negative reciprocals, so the lines are perpendicular.
Note: Negative reciprocals have a product of -1. 2(-1/2) = -1
