Answer:

x = 12

Step-by-step explanation:

-3x+12=48

-12 -12

*subtract 12 from both sides

-3x = 36

-3x/3 = 36/3

*divide 3 from each sides

x = 12

Which function represents the data in the table

Zolol [24]

It would be d because if you plug in f(6)=(3/2)+1 it would be f(6)=3+1 or f(6)=4. This works for any other of the coordinates.

X = y = (3y + 2) 4x° 52°

antiseptic1488 [7]

TO GET Y I WILL USE THE REASON SUM OF ANGLES IN A TRIANGLE:

$52 + 90 +( 3y + 2) = 180 \\ 52 + 90 + 2 +3 y = 180 \\ 3y = 180 - 90 - 52 - 2 \\ 3y = 36 \\ \frac{3y}{3} = \frac{36}{3} \\ y = 12$

y=12°

TO FIND X I WILL USE THE REQSON ALTERNATE ANGLES

$4x = 52 \\ \frac{4x}{4} = \frac{52}{4} \\ x = 13$

x=13°

THEE ANGLES ARE INSIDE THE PARALLEL LINES :NOTE.
