For the parallelogram, if m< 2+5x-28 abd m< 4=3x-10, find m< 3.

Opposite angles of a parallelogram are equal, so: 

5x - 28 = 3x - 10 

2x = 18 

x = 9 

Plug x = 9 into the equations 

m angle 2 = 5x - 28 = 5 * 9 - 28 = 17 

m angle 4 = 3x - 10 = 3 * 9 - 10 = 17 

The sum of all angles in a parallelogram is 360, 

and we know: m angle 1 = m angle 3, so: 

m angle 1 + m angle 2 + m angle 3 + m angle 4 = 360 

m angle 3 + 17 + m angle 3 + 17 = 360 

2 * (m angle 3) = 360 - 17 - 17 = 326 

m angle 3 = 163

The discount is 8.70 . you dont tell us the percent of tax added so there is no way to find out, unless i'm not seeing anything. without tax its 37.70

(6,1)(5,4)slope = (4 - 1) / (5 - 6) = 3/-1 = -3y = mx + bslope(m) = -3use either of ur , = 6 and y = 1now sub and find b, the y int1 = -3(6) + b1 = -18 + b1 + 18 = b19 = bso ur equation is : y = -3x + we need it in standard formy = -3x + 3x to both sides3x + y = 19 < == standard form
