For parallel lines, slopes are equal.
5x - 3y = -10
3y = 5x + 10
y = 5/3 x + 10/3
Required slope = 5/3
C-53.62 times however many she bought.
so c-(53.62x)
because you are taking how much money she spent and subracting it from how much she had
149 will be rounded to 150 so 150×5= 750
So for this, you'll be using the pythagorean theorem, which is
. In this case, 10 and 24 are the legs, and AB is the hypotenuse. Our equation will be 
Firstly, solve the exponents: 
Next, combine 100 and 576: 
And lastly, square root both sides to get 
And in short, Line AB is 26 ft, or the first option.
