You would just multiply $0.22 8 times then add the $0.54 to it and you get $2.30

$2.74 because the first one is 54 cents so that is one away from the nine. multiply the 22 cents by 9. then add the 54 cents

Write an equation for a rational function with: Vertical asymptotes at x = -1 and x = 3 x intercepts at x = -2 and x = -6 Horizo
dlinn [17]

Answer:

\frac{7(x+2)(x+6)}{(x+1)(x-3)}

Step-by-step explanation:

The vertical asymptotes need to be in the denominator. They become VA's when that small expression value equals zero.

x=-2 will become (x+2)

and x=-6 will become (x+6)

The x intercepts will be in the numerator.

x=-1 will go with (x+1) and x=3 will go with (x-3)

The horizontal A must be the quotient of the coefficient of the numerator and denominator, since both the top and bottom have the same power.

To make the quotient 7, we place a seven in the numerator so 7/1=7.

Is 2.0 a solution to the equation?<br><br> X-2y=0 , 2x-3y=1
Travka [436]
No, because (2,0) is a coordinate. x=2 and y=0. So just plug in the numbers where there's x or y with the appropriate number, (2 or 0). So in the first equation, x-2y=0, when you pug in the numbers, 2-2(0)=0, you know it's wrong because 2-0=0 isn't correct. So no. the point (2,0) is not a solution to the first equation. Now plug in the numbers for the second coordinate. You get 2(2)-3(0)=1. So 4-0=1. This is once again false no no. (2,0) satisfies neither equations.

Describe how to transform:
Anna71 [15]

Answer:

x^\frac{35}{6}

Step-by-step explanation:

The expression to transform is:

(\sqrt[6]{x^5})^7

Let's work first on the inside of the parenthesis.

Recall that the n-root of an expression can be written as a fractional exponent of the expression as follows:

\sqrt[n]{a} = a^{\frac{1}{n}}

Therefore \sqrt[6]{a} = a^{\frac{1}{6}}

Now let's replace a with x^{5} which is the algebraic form we are given inside the 6th root:

\sqrt[6]{x^5} = (x^5)^{\frac{1}{6}}

Now use the property that tells us how to proceed when we have  "exponent of an exponent":

(a^n)^m= a^{n*m}

Therefore we get:  (x^5)^{\frac{1}{6}}=x^{\frac{5}{6}}}

Finally remember that this expression was raised to the power 7, therefore:

[tex](\sqrt[6]{x^5})^7=(x^\frac{5}{6})^7=x^\frac{35}{6}[/tex]

An use again the property for the exponent of a exponent:
