If x and y are whole numbers that don't have10 as a factor, and if xy = 1,000, find x + y.
2 2*2*5*5*5
2*2 2*5*5*5
To solve for x and y when xy = 1,000, you can use the substitution method. First, rewrite the equation as x = 1000/y. Then, substitute this value of x into the original equation to solve for y. Once you have a value for y, you can plug it back into the equation x = 1000/y to solve for x.
Yes, you can use a calculator to solve for x and y. Most scientific calculators have the ability to solve equations with two variables, such as xy = 1,000. Simply input the equation and the calculator will give you the values of x and y.
Yes, there are multiple solutions for x and y when xy = 1,000. For example, x = 250 and y = 4 is one solution, as well as x = -500 and y = -2. It is important to check your answers by plugging them back into the original equation to ensure they satisfy the given condition.
Yes, you can use algebraic manipulation to solve for x and y when xy = 1,000. You can rewrite the equation as x = 1000/y and then use basic algebraic operations, such as factoring and simplifying, to solve for y. Once you have a value for y, you can plug it back into the equation x = 1000/y to solve for x.
The equation xy = 1,000 can be applied in various real-life situations, such as calculating the dimensions of a rectangle with a fixed area of 1,000 square units. It can also be used in finance, such as determining the interest rate when the principal and final amount are known to be 1,000. Additionally, this equation can be used in science and engineering to calculate values for variables that are inversely related.
