The quadratic formula cannot be used to solve an equation if the coefficient of the equation's x2-term is 0.
What is the equation for 1 divided by the sum of 2 and n?
0.5
What happens when you try to calculate the slope of a vertical line?
You cannot: the slope is not defined.
The quadratic formula cannot be used to solve an equation if a term in the equation has a degree higher than?
Two.
Explain why the roots of a quadratic equation are imaginary if the value of the discriminant is less than 0?
The square of any real number is non-negative. So no real number can have a negative square. Consequently, a negative number cannot have a real square root. If the discriminant is less than zero, the quadratic equation requires the square root of that negative value, which cannot be real and so must be imaginary.
What is the slope intercept form when a vertical line is passing through 5 -8?
The slope of a vertical line is undefined and so there cannot be a slope-intercept form of the equation.
Why can you not write an equation of a vertical line?
A vertical line has the equation x = C (a constant value), where y has all values, x has only one value, and the slope is undefined (the run, Δx, is zero, so you cannot divide the rise by the run).
Explain statically indeterminate structure?
The structures which cannot be solved by the equilibrium equation are known as indeterminate structures.
Are all linear equations functions why or why not?
The equation x=c where c is a constant is the equation of a vertical line. It can't be a function but it is linear so the answer is no. For example, the vertical line produced by the linear equation x = 3 does not represent a function. We cannot write this equation so that y is a function of x because the only x-value is 3 and this "maps" to every real-number y.
How do you graph if there is no slope?
A line with no slope is a vertical line. The slope is undefined, and cannot be represented by a real number. A horizontal line has a slope, but the slope is zero. Consider the "y = mx + b" form of the straight line equation. For a horizontal line the slope is zero, so y = 0x +b => y = b, which is the equation of a horizontal line. For a vertical line, there is no slope, so you can't substitute for m; the equation can't be written in the form y = mx +b. The equation of a vertical line has the form x = a.
Exactly vertical or perpendicular?
There is no such thing as exactly vertical because either it is vertical or it is not. You cannot have approximately vertical - it is not vertical, then. Vertical means at 90 degrees to the horizon (or horizontal).
What is the slope of the line with equation y -7x?
y - 7x is not an equation, it is an expression. An expression cannot have a slope.y - 7x is not an equation, it is an expression. An expression cannot have a slope.y - 7x is not an equation, it is an expression. An expression cannot have a slope.y - 7x is not an equation, it is an expression. An expression cannot have a slope.
A graph that is verticle?
Cannot exist. And a vertical graph is simply a vertical graph!
What is the vertical angle of 43?
An angle of 43 degrees cannot be a vertical angle. A vertical angle, by definition, is 90 degrees
What is the equation for Standard Form?
Ax+By=C A- Cannot be negative Equation- Cannot have decimals or fractions in it
How can you get a linear equation from 3 coordinates?
You cannot. You need four coordinates (two horizontal and two vertical) to uniquely identify two points. Having identified the two points, you can determine the slope (or gradient) as [difference in vertical coords]/[difference in horizontal coords] Then use this slope (m) and either of the two points in the equation y = mx + c to determine the value of c.
What is the slope for the equation 7?
Equation 7 is not an equation and so cannot have a slope.
