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

What is the solution set of (3x - 1)^2 = 5?<br><br><br> HEEEELLLLLLLLLLLPPPPPPPPP
babunello [35]

*I'll be keeping the solutions in exact form*

So firstly, square root both sides. This will split the equation into two:

3x-1=\sqrt{5} \\ 3x-1=-\sqrt{5}

Next, add 1 on each side: 3x=\sqrt{5}+1 \\ 3x=-\sqrt{5}+1

Next, divide 3 on both sides, and your answers will be x=\frac{\sqrt{5}+1}{3},\frac{-\sqrt{5}+1}{3}
