The line of best fit has the equation = -3 + 2.5x. What does this equation predict for a value of x = 3?
Answer: 4.5
Divide both sides by 64 to find the value of x
Yes. (Assuming that -3x2 is the best representation of 3x2 that this browser will allow.)
Using the quadratic equation formula:- x = -0.5447270865 or x = 2.294727086
If x squared equals n, then x is the square root of n.
2x + 6y = 93x - 12y = 15Chose the second equation because you can simplify it.3x - 12y = 15 divide by 3 to both sidesx - 4y = 5 add 4y to both sidesx = 4y + 5Replace 4y + 5 for x to the first equation.2x + 6y = 92(4y + 5) + 6y = 98y + 10 + 6y = 914y = -1y = -1/14x = 4y + 5x = 4(-1/14) + 5x = -2/7 + 5x = -2/7 + 35/7x = 33/7
Divide both sides by 64 to find the value of x
You cannot go beyond x = k unless you know the value of k. And in that case, the equation is solved so there is nothing further to do!
Which of the following is the best translation of this equation?
The line of best fit is used to predict future decisions.
Take the square root of both sides of the equation

Strictly speaking the above equation is a tautological equation or an IDENTITY. An identity is true for all values of any variables that appear in it. Thus, the above "equation" is true for all value of x. - that is, it has infinitely many solutions.
undefined.
"1 plus 1" has no variable, no "equals" sign, and no unknown. It's not an equation, and it asks no question. In order to come up with an "answer", one would first have invent a question. "1 plus 1" is at best an arithmetic expression with a numerical value of 2.
Exponent
It depends on which variable you wish to solve for.
