The pont (2,-1)lies on the straight line 3y=x+d a) calculate the value of D

b) another straight line passea through the pont (0,5) and through the point(3,-4)

(i)whats the equation of the line​

answer: h

step-by-step explanation:

ab will be equal to

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°

d. corresponding side lengths in similar triangles are proportional in length.
