The line 5x − 2y = −6 <=> 2y = 5x + 6 <=> y = (5/2)x + 3, has the slope a = 5/2
=> Another line (y = a'x + b) that is perpendicular with this line, must has slope a', that satisfies: a' x (5/2) = -1 => a' = -2/5
=> y = (-2/5)x + b
This line passes (5, -4), then we have:
-4 = (-2/5)*5 + b => -4 = -2 + b => b = -2
=> Solution is y = (-2/5)x -2
Hope this helps!

Answer:
x = 54° y = 126°
Step-by-step explanation:
Interior angles of a triangle = 180°
Therefore x = 180 - 80 - 46 = 54°
y = 180 - x = 180 - 54 = 126°
Answer:
y = -3/2x + 2
Step-by-step explanation:
Since you know it has a point at (0, 2) - the y intercept, put those values into the equation and solve. To be perpendicular it seems the reciprocal of the slope with the opposite sign, so 2/3 is the original slope, and -3/2 becomes the new slope.
y = 2/3x + 8 becomes
2 = -3/2(0) + b We substitute in the x and y values, but we have to figure out what the last number will be.
2 = 0 + b
b = 2
So put the whole equation together
y = -3/2x + 2
Answer:
30
Step-by-step explanation:
30/-5=-6
due to integer rules the number would be negative
Step-by-step explanation:
-3(2x-6)+4=-6x+18+4=-6x+22
