Solve the equation -2(y - 1) = 9

-7/2

Step-by-step explanation:

−2(y−1)=9

(−2)(y)+(−2)(−1)=9       (Distribute here)

−2y+2=9  

−2y+2−2=9−2           (Substract 2 from both sides)

−2y=7                         (Divide both sides by -2)

y= -7/2

have a spoopy halloween lol :'D

-3.5

Step-by-step explanation:

-2(y-1)=9

-2y+2=9

9-2=7

7/-2y

-3.5

a. 74 degrees

step-by-step explanation:

because the lines through the side and the box in the corners shows that these are congruent triangles and since they are mirrored the 37 degrees is also mirrored so the answer is 37 * 2 which is 74.
