Answer:
The slope is -9
and the interpretation is that the percentage that drops on the battery per hour is 9%
Step-by-step explanation:
Generally, the equation of a straight line can be represented by the formula;
y = mx + b
where m is the slope and b is the y-intercept
With respect to the given equation, the slope is -9
What it means is that the percentage that drops per hour on the battery is 9%
She will pay $139.23 (which is rounded up from $139.2255).
You take the price of the dress, and subtract it from 50 percent off, which gives you $119.995. You then add in the price of the shoes, which gets you to $154.695. You then subtract the 10% off from $154.695, which gets you $139.23 after it's rounded up.
Step-by-step explanation:
-0.5x >= 4
x <= -8 (divide by -0.5, flip the inequality sign)
Hence the correct number line is the 2nd one.
