Because the angles are equal to each other, you can set the two quantities equal to each other and solve for x. x=20
Multiply the first equation by 2 or divide the second one my 2, to get the #X opposites, to cancel each other out
-4x+6y=12
4x-6y=-6
Or
-2x+3y=6
2x-3y=-3
there’s no solution either way
Answer:
2
Step-by-step explanation:
Answer:
C. Slope is 2
Step-by-step explanation:
Since this equation is written in the y=mx+b equation, 2 would be the slope, because any number that comes before x (AKA "m") is always the slope. For example, if you were trying to find the slope for the equation y=4x+19, 4 would be the slope.
Answer:
The equation of the line that passes through (1, 2) is y = - 2x + 4
Step-by-step explanation:
2x + y - 1 = 0
2x + y - 1 + 1 = 0 + 1
2x + y = 1
2x - 2x + y = 1
y = - 2x + 1
parallel lines have the same slope, so the equation line will be -2
plug in the point, y = mx + b (x, y)
y = (-2)x + b , (1, 2)
(2) = (-2)(1) + b
2 = -2 + b
2 + 2 = -2 + 2 + b
4 = b
y = - 2x + 4
