What is a polynomial?

  - In mathematics, a polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponentiation of variables

What is a rational function?

- In mathematics, a rational function is any function that can be defined by a rational fraction, which is an algebraic fraction such that both the numerator and the denominator are polynomials.

Are all polynomials rational functions?

.A function that cannot be written in the form of a polynomial, so no they are not all functions.

The composite function G(F(x)) = 4√x is for the functions when F(x) = √x and G(x) = 4x.

Composition of two functions f and g can be defined as the operation of composition such that we get a third function h where h(x) = (f o g) (x).

h(x) is called the composite function.

Given that, the composite function is,

G(F(x)) = 4√x

We have to find the functions G(X) and F(x).

We know that,

G(F(x)) is the function G(x) when x is changed to F(x).

Let G(x) = 4x

In G(F(x)), x will be replaced by F(x).

In order to get 4√x, x is replaced by √x.

So, F(x) = √x

Hence G(x) = 4x and F(x) = √x.

Answer:

A quadratic function is a second degree polynomial function. The general form of a quadratic function is this: f (x) = ax2 + bx + c, where a, b, and c are real numbers, and a≠ 0.

Answer:

The answer is t = 17

Step-by-step explanation:

Sum of angles on a straight line = 180⁰

(2t -7) + 90 + 49= 180

(2t -7) +139 = 180⁰

2t -7) = 180 - 139

2t - 7 = 41

2t = 41 - 7

2t = 34

Divide both sides by 2

t = 17

Answer:

The slope is y = x

Step-by-step explanation:

You can find the slope by using the rise over run method with two points.Let's take (1,1) and (2,2). From the first point to the second point, (1,1) goes up one unit and to the right one unit.So the rise over run is 1/1, or 1, which means the slope is 1.

Answer:

m = 1x

Step-by-step explanation:

This is the easiest slope you'll ever have to calculate - if you even need to as it's self explanatory looking at it! Slope = rise/run, thus slope = 1/1 = 1.

Answer:

500 centiliters

Step-by-step explanation:

Using a phase is helpful for conversions. I like this one "King Henry died by drinking chocolate milk".

K- Kilo : 0.001

H- Hecta : 0.01

D- Deca : 0.1

b- base (gram, liter, meter, etc) : 1

d- deci : 10

c-centi : 100

m-milli : 1000

For every step up or down you move the decimal one place over depending on if you go up or down.

So, for 2.5L as centiliters you would move the decimal over two spots giving you 250 centiliters. You can also multiply or divide by 10 for each step taken. so for two steps you would multiply by 100, also giving you an answer of 250 centiliters. This is then multiplied by two as 250 cL was dumped twice.

Answer:

Step-by-step explanation:

The division property states that when we have an equation in the form [tex]ax=b[/tex], then [tex]x=b/a[/tex](i.e. we "divide" by [tex]a[/tex] on both sides).

So, Mark was supposed to get [tex]x=9/23[/tex], which is not equal to [tex]6[/tex].

So, Mark solved it [tex]\boxed{wrong}[/tex]

No, Mark solve the equation correctly.

because, Mark was supposed to get x = 27/2 , which is not equal to x= 6.

The division property of equality applicable.

The division property of equality is a property that tells us if we divide one side of an equation by a number, we must also divide the other side by the same number so that our equation stays the same. The formula for this property is if a = b, then a / c = b / c.

We have the following information available from the question is:

The equation is:

[tex]\frac{2}{3}x=9[/tex]

It solved by using the Division Property of Equality and get x = 6

If we solved for x: then,

x = 27/2

No, Mark solve the equation correctly.

So, Mark was supposed to get x = 27/2 , which is not equal to x= 6.

yea i agree  with scorpiowo the asnwer is B

Step-by-step explanation:

The slope of that line is -1, so m = -1.

The point you were told to use is (-2,2), so point-slope form starts as:

   ( y - 2 ) = -1 • ( x - (-2) )

But we'd clean up that x-(-2) to be x+2.

   y - 2 = -1 ( x+2 )
