Answer:

  (5, 1) or maybe (h, k)

Step-by-step explanation:

The given form has no letters other than the variable. The vertex in this vertex-form equation can be read from the expression as (5, 1).

In the generic vertex form ...

  f(x) = a(x -h)² +k

the letters (h, k) are used to represent the vertex.

__

You would need to consult your curriculum materials to see what letters your author uses for the vertex in vertex form.

Vera is using her phone.Its battery life is down to 2/5,and it drains another 1/9 every other. How many hours will her battery l
Margarita [4]

Let x be total hours of battery life. We have been given that battery life of Vera's phone is down to 2/5. So remaining battery life,

1-\frac{2}{5}=\frac{5-2}{5}=\frac{3}{5}

We have been also given that it drains another 1/9 every other hour. Now let us substitute our given information into an equation.

\frac{1}{9}\cdot x=\frac{3}{5}

Now we will solve for x.

x=\frac{3\cdot 9}{5}=\frac{27}{5}

x=(5+\frac{2}{5})hours

Let us convert 2/5 into minutes. We know 1 hour has 60 minutes.

60\cdot \frac{2}{5}=24\text{minutes}

Therefore, remaining battery life will be 5 hours and 24 minutes.

4x-10=30<br> 2n-7=30 <br> S/3+2=4
emmasim [6.3K]

Answer:

x=10 n=18.5 s=6

Step-by-step explanation:

4x-10=30

Add 10 to both sides

4x-10+10=30+10

4x=40

Divide by 4 on both sides

(4x)/4=40/4

x=10

2n-7=30

Add 7 to both sides

2n-7+7=30+7

2n=37

Divide by 2 on both sides

(2n)/2=37/2

n=18.5

(s/3)+2=4

Subtract 2 from both sides

(s/3)+2-2=4-2

(s/3)=2

Multiply by 3 on both sides

3s/3=2*3

s=6
