Answer: y = -3/2x -5
explanation:
y = mx + b
7 = -3/2(-8)+b
7= 12 +b
subtract 12 on both sides
-5 = b
y = -3/2x - 5

Answer:
x = 21/4
Step-by-step explanation:
re-arrange the equation
-4+5x-7-3x = 10-2x (move 3x to the other side)
-4+5x-7-3x+2x = 10 (move 2x to the other side)
5x-7-3x+2x = 10+4 (move 4 to the other side)
5x-3x+2x = 10+4+7 (move 7 to the other side)
4x = 21 (add up both sides)
x = 21/4 (divide both sides by 4
| r + 3 | > 7
r + 3 > 7 r + 3 < -7
r > 7 - 3 r < -7 - 3
r > 4 r < -10
so, r > 4 and r < -10
==========================
what percent of 60 is 12
percent formula : is/of = %/100
percent = x
is = 12
of = 60
now sub
12/60 = x/100
cross multiply
60x = 12 * 100
60x = 1200
x = 1200/60
x = 20%
