The volume equals length x width x height so multiply all of those with a calculator and you’ll get your answer hope I helped :)
The equation would be:
m = 30b where 'm' represents the amount of money and 'b' represents the number of boxes sold.
m is the dependent variable
b is the independent variable
Answer:
x = 5, y = -1/2
Step-by-step explanation:
3.5x - 5y = 20
3x + 4y = 13 multiply by 1.25 so the y's match up (you could match x's too)
3.75x + 5y = 16.25
–––––––––––––––––––––––
3.5x - 5y = 20
3.75x +5y = 16.25
7.25x + 0y = 36.25 you can add or subtract here (on this equation you add)
7.25x=36.25
x=5 So now we have x=5 and to find y we can just plug in x into one of the equations
–––––––––––––––––––
3(5) + 4y = 13
15 + 4y = 13
4y = -2
y = -1/2
x = 5, y = -1/2
Then you can plug in both to check your answers.
Answer:
line of best fit
Step-by-step explanation:
line of best fit is NOT a method for solving a quadratic equation.
Rest of all the methods are used for solving a quadratic equation.
