Jade spent 1/2 of a hour playing on her phone. That used up 1/9 of her battery. How long would she have to play on her phone to use the entire battery

4.5 hours

Step-by-step explanation:

.5 spends 1/9

1 spends 2/9

1.5 spends 3/9

2 spends 4/9

2.5 spends 5/9

3 spends 6/9

3.5 spends 7/9

4 spends 8/9

4.5 spends 9/9 or 1 full battery

step-by-step explanation:

i dont get

asnwer is (g o h o f)(x) = 2x - 6/x + 7

step-by-step explanation:

given,

f(x) = x - 3/x

g(x) = x + 3

h(x) = 2x + 1

we need to find : (g o h o f)(x)

we can write (g o h o f)(x) = g[ h{ f(x) } ]

so first we find h{f(x)}

h{f(x)} = f(x) + 3 = (x - 3/x) + 3

h{f(x)} = x - 3/x + 3

now we find g[ h{ f(x) } ].

g[ h{ f(x) } ] = g(x - 3/x + 3)       {plug h{f(x)} = x - 3/x + 3 in g[h{f(x)}] }

g(x - 3/x + 3) = 2 (x - 3/x + 3) + 1

                    = 2x - 6/x + 6 + 1

                    = 2x - 6/x + 7

hence we get (g o h o f)(x) = 2x - 6/x + 7
