Answer:
Since two points determine any line, we can graph lines using the x- and y-intercepts. To find the x-intercept, set y = 0 and solve for x. To find the y-intercept, set x = 0 and solve for y. This method of finding x- and y-intercepts will be used throughout our study of algebra because it works for any equation.

Answer:
x=8,9
Step-by-step explanation:
x^2-17x+72=0

Answer:
$787
Step-by-step explanation:
In terms of interest
To find the multiplier using '7% more' continues as follows
100% + 7% = 107%
107/100 = 1.07 (multiplier)
Add the ten years as a power to the multiplier
1.07^10
And multiply this by $400
400 x 1.07^10 = 786.860542916
To the nearest dollar = $787
