Select whether each function is linear or nonlinearY=9(2x)
Y=(5x+3)^2
Y=8x^2
Y=5x-3
Y=3x^2+2x-1

If I put ^ before a number it means it's an exponent if anyone doesn't know

Answers

Answer 1

Answer:

Y=9(2x) and y = 5x - 3 are linear equations while others are non-linear.

The standard linear equation is in the form y = mx + b

Note that the highest degree of linear equation is 1 while that of non-linear is 2 and above.

From the given option, we can see that the equation with the highest degree of 1 are Y=9(2x) and y = 5x - 3 (These ar linear equations)

Other equations are non-linear in nature since they have a degree of 2 or more.

Answer:

x = 86

Step-by-step explanation:

note: a straight line is regarded to have an angle of 180 degrees.

in this case CUW is a straight line

I shall show you two methods . which ever one you choose will still get the same answer. however understanding both will help you use them for other questions

method 1

therefore in order to solve the value of x we need to get the missing angle in the triangle first which is angle WUV

Angle WUV

notes : a triangle has a total angle of 180 degrees

hence we can create an equation to get the angle WUV

lets make the missing angle as Y , this will help to find the answer.

46 + Y + 40 = 180

now make Y the subject of formula

Y = 180 - 40 - 46

Y = 94

now in order to find x .

since the CUW is a straight line with 180 degrees

hence x = 180 - 94 = 86

x = 86

method 2

since the triangles total angle is 180 degrees and also the straight line is also 180 degrees. we can just add the total of the 2 sides of the triangle ( the two interior angles can be added together to get the value of the exterior one)

40 + 46 = 86

x = 86

The answer is 86
Two interior angles is equal to one exterior angle

What number to add to equal 32

Answers

Well to figure this out all you have to do is divide 32 by 2.. Which lets you know what 2 numbers were put together, or multiplied to equal 32!

So...

32/2 =16.. (work) -----> 16 + 16 = 32

So 16 is your answer!

Let f(x)=x^2 - 16. find f^-1(x).

Answers

$f(x)=x^2-16\n\ny=x^2-16\n\nx^2=y+16\n\nx=√(y+16)\n\nf^(-1)(x)=√(x+16)$

A quadratic function doesn't have inverse function. But you can find inverse function for each of its "arms".

$f(x)=x^2-16 \Rightarrow x_(vertex)=0\n y=x^2-16\n x^2=y+16\n x=-√(y+16) \vee x=√(y+16)\n f^(-1)(x)=-√(x+16) \hbox{ for } x<0\hbox{ (left arm)}\n f^(-1)(x)=√(x+16) \hbox{ for } x>0\hbox{ (right arm)}$
