Answer:

x = 5/3 x= -1

Step-by-step explanation:

|3x-1|=4

There are two solutions to the absolute value equation, one positive and one negative

3x-1 =4 and 3x-1=-4

Add 1 to each side

3x-1+1 = 4+1 3x-1+1 = -4+1

3x=5 3x = -3

Divide by 3

3x/3 = 5/3 3x/3 = -3/3

x = 5/3 x= -1

Answer: 81.2

Step-by-step explanation:

h(t) = -5t² + 40t + 1.2

h(4) = -5(4)² + 40(4) + 1.2 We plug 4 seconds as t, and solve h(4)

h(4) = -80 + 160 + 1.2

h(4) = 80 + 1.2

h(4) = 81.2
