What is the equation of the line containing the points (0, 0), (-3, -9), and (9, 27)?
you should know this Find the difference of the y values over the difference in your x values to find the slope. Put it into the slope intercept form of the equation with one of the points substituted in and find the intercept. Rewrite the equation with the slope and the intercept. (-9-0)/(-3-0)=-9/-3=3 The slope. 27=3(9)+b 27=27+b 0=b Equation-> y=3x
Which Algebraic Property is illustrated by the equation: a * b = b * a?
The Commutative Property is illustrated by this equation: a * b = b * a.
How do you find the equation of a parabola in standard form given 3 points?
I suggest that the simplest way is as follows:Assume the equation is of the form y = ax2 + bx + c.Substitute the coordinates of the three points to obtain three equations in a, b and c.Solve these three equations to find the values of a, b and c.
What two number multiply to 196 and add up to negative 28?
224
How do you do the Quadratic formula?
The general form of a quadratic equation is ax^2+bx+c=0. The quadratic formula is used to find the x intercepts of a parabola. It goes like this: x=(-b+or-the (square root of b^2-4ac))/2a. With a specific equation you plug the values for a, b, and c into the formula. It is best to use a graphing calculator. Hope this helps.
How do you solve for x using a quadratic equation?
For an equation of the form ax² + bx + c = 0 you can find the values of x that will satisfy the equation using the quadratic equation: x = [-b ± √(b² - 4ac)]/2a
What are the values of a and b given that y plus 4x equals 11 is the perpendicular bisector equation of the line joining a 2 to 6 b?
Their values work out as: a = -2 and b = 4
What is a related equation?
A related equation is a set of equations that all communicate the same relationship between three values, but in different ways. Example: a+b=c a=c-b b=c-a
What are Antoine coefficients for CH4?
The Antoine coefficients for isobutane in the temperature range of -83°C to 7°C are A=13.8254, B=2181.79, C=248.870. These coefficients are valid for Antoine's equation in the form of ln(Psat [kPa]) = A - B/(T[°C] + C). (Source Introduction to Chemical Engineering Thermodynamics 7th ed by J.M. Smith, p.682)
How do you know if an equation is linear?
You know if an equation is linear if it is a straight line. You can also know if the equation is y = mx + b where there are no absolute values nor exponents.

You know if an equation is linear if it is a straight line. You can also know if the equation is y = mx + b where there are no absolute values nor exponents.
What is the answer to ab-b-a 1?
There is no answer since there is no equation (nor an inequality), only an expression. Without the values of a and b, the expression cannot be evaluated.
What is infinite solutions?
The equation or a system of equations having infinite solutions is called identity/identities. (a+b)^2=a^2+2ab+b^2 is an identity. It has infinite solutions. The equation is true for all values of a and b.

What is General equation of a line?
The general equation to represent a line isaX + bY = c, where a, b, and c are given values or parameters.See the reference for more information.
What are the variables in this equation 3ab plus c over 2?
The variables of this equation are your letters: a, b, and c. Variables merely stand in an equation to represent values that we don't know. "Solving" an equation is the process by which we uncover those values. In this particular case, since there are three variables, we cannot discover their values unless we have two other equivalent equations (a system of equations).
What is an equation that performs mathematical calculations on number values?
A squared plus b squared equils c squared
