2x - 3(x-1) = -1
2x -3x + 3 = -1
-1x + 3 = -1
-1x = -4
x = 4
y = 4 - 1
y = 3
(-9,-2) (1,3)
slope = (3 - (-2) / (1 - (-9) = 5/10 = 1/2
y - y1 = m(x - x1)
slope(m) = 1/2
(1,3)...x1 = 1 and y1 = 3
sub
y - 3 = 1/2(x - 1)
y - 3 = 1/2x - 1/2
y = 1/2x - 1/2 + 3
y = 1/2x - 1/2 + 6/2
y = 1/2x + 5/2 <=== slope intercept form
Answer:
Beta is 60 degrees, and the angle of A should be 30 degrees.
Step-by-step explanation:
Its a right triangle, so it equals 180 degrees, there's a perpendicular angle at 'C' so its 90 degrees, B and its angle of 'Beta' 60 degrees, and angle 'A' can be 30 degrees. if in need of more explanation please look into complimentary and supplementary angles should give you a good idea.
Answer:
no solution
Step-by-step explanation:
the roots are x values where the graph interacts the x axis. to find the roots replace y with 0 and solve for x
