Tvaries inversely as the square root of u.
t = 3 when u = 4.
find t when u = 49.

t =

Step-by-step explanation:

Given that t varies inversely as the square root of u then the equation relating them is

t = ← k is the constant of variation

To find k use the condition t = 3 when u = 4, thus

k = t = 3 × = 3 × 2 = 6

t = ← equation of variation

When u = 49, then

t = =

1. x> -5

2. x< 8

step-by-step explanation:

1. 2x> -10

divide by 2 from both sides of equation.

2x/2> -10/2

simplify, to find the answer.

-10/2=-5

x> -5 is the correct answer.

2. 3x< 24

divide by 3 from both sides of equation.

3x/3< 24/3

simplify, to find the answer.

24/3=8

x< 8 is the correct answer.

i hope this you, and have a wonderful day!
