Linear functions; what are the coordinates of the point where the line y= - 2/5 x + 12 intersects the x axis?

(-30,0)

Step-by-step explanation:

y=-2/5x+12

y-12=-2/5x          (-2/5=0.4)

y/0.4-12/0.4=x

y/0.4-30=x

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°

r = 78539458390583095803458309458039485093485 or just 3
