Which equation is not a linear function?
1 answer:
<h3>Answer:</h3>
a, e
<h3>Explanation:</h3>If any of the terms has a variable with an exponent other than 1 or 0, or has a sum of variable exponents other than 1, the term is non-linear and the relation is not a linear relation.
a: the term xy has a sum of exponents of 1+1=2, so is not a linear term.
e: the term x² has an exponent other than 0 or 1, so is not a linear term.
In the attached graph, the non-linear relations are shown graphed in black. The remaining relations are all linear.

<em>Comment on linear function</em>
By one definition, a linear function is one that is of the form
... f(x) = ax + b
Here, an equation such as <em>y = x + 2y</em> can be put in that form, but it is <em>not</em> in that form as presented. Yes, the graph is of a straight line, but you would have a hard time identifying independent and dependent variables from the equation as given.

Step-by-step explanation:
The given rectangle has diagonals have the endpoints P(-3, -2) ,I(4, -7) and A(4, -2) ,D(-3, -7)
The diagonals of the rectangle bisect each other so we use the midpoint formula to find their point of intersection.
The midpoint formula is;
We use any pair of endpoints of the diagonals to find the point of intersection.
Using A(4, -2) ,D(-3, -7)

If all three side lengths are INTEGERS and form PYTHAGOREAN TRIPLE then we know decimals are not allowed
if 24 and 51 are both legs then
x = 3177
and squre root of that gives us 56.364.... NOT an integer
So that means one of them is not a leg and since hypotenuse is longer than both legs, 51 must be the hypotenuse so to get the third side
