Whats 8 multiplied by 10 to the 7th power
x = 2y
x - 8 = y + 6
replace x by 2y in the second equation
2y - 8 = y + 6
y - 8 = 6
y = 14
x = 2*14 = 28
kendra had $28 and kareem had $14.
slope intercept form is y = mx + b
the be is your y intercept (0,8)
the m is your slope (2) by putting a one under it you can graph it more easily:
to get your next point follow the slope which is
what this means is we follow the fraction and go up 2 and right one (positive slope) or down 2 and left one (positive slope) to get our next points
for a negative slope it would be up and then left or down and then right

her score in the first game was 173.
sue's total score for the 3 games = 3*162 = 486 points.
let her score in the first game be x points. then in the second game she scored (x - 10) and in the third, ( x - 10 - 13) points:
x + (x - 10) + (x - 23) = 486
3x - 33 = 486
3x = 519
x = 173 (answer).
