i.2 tan(− / 12) / 1 − tan2(− 12)
j. cos2 / 8)
k. cos / 8)
l. cos (− / 8 )
m. sin2 ( / 12)
n. sin ( / 12)
o. sin (− / 12)
p. tan / 8)
q. tan / 12)
r. tan (− / 8 )

the answer to the question is a

step-by-step explanation:

it has the same slope and the same y-intercept.

y + 11 = -7/9(x - 18)

y + 11 =-7/9x + 14

b

y = -7/9x + 3

y-intercept (0, 3)

let's solve your equation step-by-step.

24−3x=−27

step 1: simplify both sides of the equation.

24−3x=−27

24+−3x=−27

−3x+24=−27

step 2: subtract 24 from both sides.

−3x+24−24=−27−24

−3x=−51

step 3: divide both sides by -3.

−3x

−3

=

−51
