5.y=4x-4

6.y=-2x-5

Step-by-step explanation:

(i)

y=mx+c

10=(m)3+1

10=3m+1

10-1=3m

m =3

y=3x+1

I need the answer :(
madreJ [45]

Answer:

z = 62

y = 117

Step-by-step explanation:

Z

118 and z are supplementary.

z + 118 = 180 Supplementary angles add to 180. Subtract 118 from both sides.

z = 180 - 118  Do the subtraction        

z = 62            Answer

Y

The interior angles of all quadrilaterals (convex) add up to 360 degrees.

y + z + 84 + 97 = 360           Given

62 + y + 84 + 97=360          Add

y + 243 = 360                       Subtract 243 from both sides

y = 360 - 243                        combine

y = 117                                    Answer
