Two equations: a linear one in y and a quadratic in x.
no, because xx=x squared, and x squared is not linear
YES, all linear equations have x-intercepts. because of the x, y has to be there 2!
It is x-3.
Linear equations come in the form y=mx+b or y=mx-b, where x and y are the variables x and y and b is a constant (like 3). All other equations are non-linear. Linear equations has a power of 1! as long as the X has a power of 1, it is a linear equation.
No, to be linear, both the power of x and y need to be 1. Since x is squared, the power of x is 2.
Yes, the graph of a linear equation can be a line. There are special cases, sometimes trivial ones like y=y or x=x which are linear equations, but the graph is the entire xy plane. The point being, linear equations most often from a line, but there are cases where they do not.
y = x
If you already know that x = -3 and y = 5 what linear equations are you wanting to solve?
A linear equation is one in which the variable is raised to the first power (i.e. x, not x squared or x cubed or anything else). An example would be y = mx + c. In an exponetial equation the variable is part of the exponent, e.g. y = 3^x + c.
Linear equations can be written as y = mx + b. Any other function would be non-linear. Some linear equations are: y = 3x y = 2 y = -2x + 4 y = 3/4x - 0.3 Some non-linear functions are: f(x) = x2 y = sqrt(x) f(x) = x3 + x2 - 2
A system of linear equations determines a line on the xy-plane. The solution to a linear set must satisfy all equations. The solution set is the intersection of x and y, and is either a line, a single point, or the empty set.
y=9+3x is linear because there is only one value of x so it will go up proportionally, for instance if x=1 then y=12, x=2 y=15, x=3 y=18. they will always go up by three, only equations with multiple xs, eg x squared+4x+6 is non linear and x cubed-9 is non linear.
x y squared is a formula For Example- Say x was 3 and y was 5 squared Then it would be 3 squared times 5 squared 9x25=225 That would be your result..... Although... If the variables had no numbers in the equations answer... Then the answer would stay the same x y (squared)
no you smell
Functions and linear equations are the same in that they both deal with x and y coordinates and points on a graph but have differences in limitations, appearance and purpose. Often, functions give you the value of either x or y, but linear equations ask to solve for both x and y.
No, It's a a quadratic equation because you have X squared.
It is a linear equation. The highest power of x in the equation is 1 (3x1-4=12) so its "degree" is 1, and equations of "degree 1" are called linear equations.
y=3x+2 y-4x=9 These are examples of linear equations which is a first degree algebraic expression with one, two or more variables equated to a constant. So x=2 is a linear equation as is y=1 but x2 =1 is not since the variable, x , has degree 2.
Linear equations or inequalities describe points x y that lie on a circle.
These are two expressions, not equations. Expressions do not have solutions, only equations do. NB equations include the equals sign.
To solve it by coordinate graphs you would take a point from the line and plug in the X and Y value into the equations and or inequalities.
No it is a linear one. X^2 = quadratic, x = linear. So if the equation doesn't have an x squared, then it is not quadratic.
