Plz help i am in a dia and i dont understand this at all (Solve the equation shown for y.)
2(3y−4)=19−3y
A.2.6
B.3
C.7.6
D.9

y=3

so B

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable.

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

it is b)

hope this : )
