How can you tell if a function is linear by looking at the graph or the equation

Every linear graph is just a straight line, so if there are any curves or unnatural shapes, than you know it is not linear. As for equations, if it can be shaped into y=mx+b where m and b are numbers, then it will be a linear equation.

To determine the number of beavers in a conservation area, a researcher catches and marks 119 beavers. Then the researcher rele

romanna [79]

Let x be the total number of beavers. We mark 119 out of x beavers. Then, we found 39 marked beaver out of 89 caught beavers. So, if we build the proportion

$119 \div x = 39 \div 89$

we get, solving for x,

$x = \dfrac{119\cdot 89}{39} \approx 272$

So, it is reasonable to suppose that there are about 272 beavers in total. Note that this is an estimate, both numerically and conceptually, since we have no information about the set of beavers caught at the beginning and the end of our experiment.

What does it mean for an equation to have no solution or infinite solutions? How does the equation appear when those are the out

Sati [7]

Ok so if a system has no solutions, that means that no value will make it true

infinite solutions means that all numbers wil make the system true

example of no solution

a simplification that gives you
3=0
that is false so no solution

example of infinite
if after simplify you get
x=x
you can put all numer for x and get right answer

the simplified form of an equation with no solution will be in the form a=b where a is not equal to b, basically it gives you an obviously false statement like 3=4

simplified form on an equation with infinity solutions would end up with variable=variable or x=x or y=y
