Given a = -3, b = 4 and c = -5, evaluate a + b + c. -4 -6 -12

-4

Step-by-step explanation:

-3 + 4 + -5 = -4.

Hope this helps.

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
