Answer:
<h2>The slope m = 2</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
<em>y = mx + b</em>
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
<em />
We have the equation:
<em>y = 2x - 1 → m = 2, b = -1</em>
at x = 0, y = 100, y-intercept
meaning at 0 years, at the very beginning of functioning, the satellite had 100 units of power.
at y = 0, x = 10, x-intercept
meaning, at year 10, the satellite had 0 units of power, already out of power.
Distributive property is in the form of:<span>
a (b+c) = ab + bc</span>
<span>
In this case, we try writing 47 as:</span>
47 = 50-3 or 47 = 40+7
Therefore:<span>
11 x 47 = 11 x (50-3) = 11 x 50 - 11 x 3 = 550 - 33 =
517
or
<span>11 x 47 = 11 x (40+7) = 11 x 40 + 11 x 7 = 440 + 77 =
517</span></span>
