How can you tell if a function is linear or non linear?
If it can be written in the form y = mx + c where m and c are constants [or, equivalently, ax + by = k where a, b and k are constants] then y is a linear function of x.
What are 5 forms of equations of lines?
Standard form: ax + by + c = 0 (a, b, c constants, x and y variables)Slope intercept form: y = mx + c (m, c constants, x and y variables)Two points form: given P = (a, b) and Q = (c, d)(y - b)*(x - a) = (d - b)*(c - a ) (a, b, c, d constants, x and y variables)Parametric equation x = a + r*cos(t), y = b + r*sin(t) (a, b, t constants, x and y variables)X = A + k*B (X, A and B vectors, k scalar, X and k variables).The standard form, parametric equation and vector form have simple analogies for 3 or more dimensions.
General form for hyperbolas?
The most general form is (ax - b)*(cx - d) = k where a, b, c, d and k are constants.
What does in terms of a specific variable in maths mean like finding something in terms of k what if that something is an expression of k and some constants is it still in terms of k?
It means rearrange the given equation so the the term in k is on one side and everything else is on the other eg i= ptr/100k in terms of k is calculated as: step 1; cross-multiply: 100ki = ptr; step 2; divide both sides by 100i: k = ptr/100i
What is k- 4.05 equals 6.2?
I am supposing you are looking for k, in that case you add 4.05 to both sides of the equation to cancel out the 4.05 on the k side, making the equation k = 10.25
