Which graph matches the exponential function f(x) = (3)x?

How do you determine whether a relationship represented as as graph is linear or nonlinear

3x + 4y = 5 x- 3y = -7 solve by substitution

*let m∠cob = 50°30’, m∠aob = 70° and m∠aoc = 20°30’. could point c be in the interior of ∠aob? why? a. point c could be the interior of aob but it is not the only case b. point c is the interior of aob c. point c is not the interior of aob d. the given is not possible for the plane geometry answer
