What is another pattern for 2,3,6,7,14,15,30,31,62,63,126,127
lana [24]
127,126,63,62,31,30,15,14,7,6,3,2
Ratio of Anne : Mark : Ben = 20 : 35 : 25
= 4 : 7 : 5 ( total 16 parts )
Anne = 4/16 x £80 = £20
Mark = 7/16 x £80 = £35
Ben = 5/16 x £80 = £25
2x -3y = 12;
x + 3y = 6;
__________(+)
3x = 18;
x = 18÷3;
x = 6;
Then, 3y = 6 - 6;
3y = 0;
y = 0÷3;
y = 0;
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.
