The number -2 is a solution to which of the following inequalities?
-3x < 1
x - 7 < -4
-12/x> 10
x + 7 > 5

Substitute the value of x = -2 to the inequalities:

-3x < 1

(-3)(-2) < 1

6 < 1 FALSE

x - 7 < -4

-2 - 7 < -4

-9 < -4 TRUE

-12/x > 10

-12/(-2) > 10

6 > 10 FALSE

x + 7 > 5

-2 + 7 > 5

5 > 5 FALSE

x - 7 < -4

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

maximum area = xy = (16)(32) = 512 ft2

to maximize the area of the garden, the side of the fence parallel to the side of the house should be 32 ft long, and the other two sides should both have length 16 ft.'
