Y(5y) + y(4) + 3y^2
5y^2 + 4y + 3y^2
8y^2 + 4y
Answer:
60
Step-by-step explanation:
5*3=15
3*3=9
4*3=12
4*3=12
4*3=12
(12*3)+9+15= 60
A varies directly with b → a = kb where k is the constant of variation (i.e. slope)
-2 = k × 3 ← substitute values into the formula above
-2/3 = k ← result of dividing both sides by 3
Answer: k =
Answer:
1. x = 2
2. x = 4
Step-by-step explanation:
1. 6 - 4x = 6x -8x + 2
6 - 4x = -2x + 2
+4x +4x
6 = 2x + 2
-2 -2
4 = 2x
/2 /2
2 = x
2.
6 - 6x = 5x -9x -2
6 - 6x = -4x -2
+6x +6x
6 = 2x -2
+2 +2
8 = 2x
/2 /2
4 = x
