Work out the value of x

67.5°

Step-by-step explanation:

Given, 90° + x + 3x = 360°

4x = 360° - 90°

4x = 270°

x = 67.5°

67.5

Step-by-step explanation:

i think this is the answer

y=−9/2x+10

step-by-step explanation:

let's solve for y.

0−9x−2y=−20

step 1: add 9x to both sides.

−9x−2y+9x=−20+9x

−2y=9x−20

step 2: divide both sides by -2.

−2y

−2

=

9x−20

−2

y=

−9

2

x+10

c: y > - 1/6x + 1

step-by-step explanation:

dashed line - meaning this < or > also not equal

solid line - meaning this < or > also equal

your answer is c because y > means up & it's shaded up, but y < means down

hope this ! : )
