Answer:
y=3x-7
Step-by-step explanation:
Two points on the line are (3,2) and (4,5) using the slope equation, 5-2/4-3=3/1
y-2=3(x-3)
(2+) y-2=3x-9(+2)
y=3x-7
You would add 4y to both sides of the equation which would leave you with
4y - 3 = 8x
then you would divide the entire equation by 4 leaving you with
y - 3/4 = 2x
then you would add 3/4 to both sides of the equation leaving you with
y = 2x + 3/4
your answer is the first one, MNO is similar to GHK
the sum of the interior angles of a triangle is 180°
MNO
180 - 22 - 79 = 79° (angle N)
GHK
180 - 79 - 79 = 22° (angle K)
From here you see that they have the same angles, so they are similar.
Its a simultaneous equation:
lets make "x" the used games and "y" the new ones
4x + 2y = 84
6x + y = 78. (multiply this by 2 to cancel out y)
12x + 2y = 156
so now we subtract them:
12x - 4x = 156 - 84
x = 9
used games cost $9
new games cost 78 - 6(9) = $24
Janet has $120 but she already bought 3 NEW games so:
120 - 3(24) = $48 left
48/9 = how many used ones she can buy = 5. something
she can buy 5 used
