What is the line of symmetry for the parabola whose equation is y x2 - 12x 7?
y=x2-12x+7
Is 6x plus -7 a linear equation?
-1
How can you tell that an equation is linear?
In a linear equation, the highest power of all variables is 1. eg y = x + 3 In this example, the variable (x) has a power of 1 (remember, x1 is the same as x). Therefore, a linear equation. eg 2 y = x2 +7 eg 3 y = p3 + p - 89 In example 2 and 3, variables have a power higher than 1. Hence, they are non-linear equations.
Is 2x equals 7 a linear equation?
yes
When does the nonlinear equation becomes linear equation?
A linear equation is defined as an equation that contains only the first power of the unknown quantity. For example, 5x - 3 = 7 where "x" is the unknown quantity is a linear equation. If an equation contains an unknown quantity having a higher power than 1, then the equation ceases to be a linear equation. For example, 3x2 + 5x + 7 = 0 is a non linear equation known as a quadratic equation, because the unknown quantity "x" has a power of 2. Similarly, equations containing unknowns with higher powers such as x3, x7, x12 are all non linear equations.
How can the degree of the equation tell us if the equation is linear or not?
A linear equation always has a degree of one because the slope has to be constant to form a line. So, x + 7 is linear, 7 - x is linear, 4x - 3.7 is linear, but anything with x2 , etc. is not linear.
Is y plus 4x equals 7 a linear equation?
Yes, y = 4x + 7 is a linear equation.

How do you solve xsquared 2x minus7?
x2 + 2x - 7 is a quadratic polynomial. Every polynomial defines a function called P. Any value of x for which P(x) = 0 is a root of the equation and a zero of the function. x2 + 2x - 7 = 0 add 1 and 7 to both sides x2 + 2x + 1 = 8 (x + 1)2 = 8 take the square root of both sides x + 1 = ± √8 subtract 1 to both sides x = -1 ± 2√2 Thus, the roots of the equation are -1 - 2√2 and -1 + 2√2.
Is y=2x+5 a linear equation?
7
Is 2x equals 7 a linear equation?
