Vera is using her phone. Its battery lifw is down to 2/5 and it drains another 1/9 fraction every hour. How long will her batter

just olya [345]

Battery is down currently = 2/5

Battery drains at the rate of 1/9 every hour.

Remaining battery life of Vera = 1 -2/5 = 3/5

Let y we the number of hours battery will last.

So, 1/9 y = 3/5

y = 27/5

y = 5 + 2/5 hours

y = 5 hrs and 24 mins

So battery will last another 5 hrs and 24 mins.

hope this helps:)

Write an inequality for the given graph.

Gekata [30.6K]

Answer:

$y$

Step-by-step explanation:

<em>Find the equation of the dashed line</em>

The line pass through the points

$A(0,-3)$ -----> is the y-intercept of the line

$B(6,0)$

Find the slope of the line m

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values

$m=\frac{0+3}{6-0}=0.5$

Remember that

The equation of the line into slope intercept form is equal to

$y=mx+b$

we have

$m=0.5$

$b=-3$

substitute

$y=0.5x-3$

<em>Find the inequality</em>

we know that

The solution of the inequality is the shaded area below the dashed line

$y$
