Evaluate when x = 0 and y = 9: 14x - 3xy + 6x - y *

Step-by-step explanation:

14(0)-3(0)(9)-3(0)(9)+6(0)-9

=0-0-0+(-9)

=-9

constants mean the stopped points or the points on a graph that nothing is changing, hope this

step-by-step explanation:

m∠5 + m∠3 = m∠1   is true.

m∠5 + m∠6 = 180 is true

m∠2 +m∠3 = m∠6   is true

m∠2 +m∠3 +m∠5 = 180   is true
