Answer:
a) 67
b) x= -8 and 4
c) 31
Step-by-step explanation:
a) if m<1 = (6x - 5) and m<5 = (5x+7), find m<3.
6x - 5 = 5x + 7
-5x + 5 - 5x + 5
x = 12
6(12) - 5 = 5(12) + 7
72 - 5 = 60 + 7
67 = 67
b) if m<4 = 32 and m<8 = (x^2 - 4x), find x.
32 = x^2 - 4x
- 32 - 32
x^2 - 4x - 32
(x - 8)(x + 4)
x - 8 = 0 x + 4 = 0
+ 8 + 8 - 4 - 4
x = -8 and 4
c) if m<4 = (4x - 17) and m<5 = (5x - 29), find m<1.
4x - 17 = 5x - 29
-5x + 17 -5x + 17
-x = -12
/-1 /-1
x = 12
4(12) - 17 = 5(12) - 29
48 - 17 = 60 - 29
31 = 31
