Mathematics

Answer:

Step-by-step explanation:

Remark

If the trinomial is going to factor, it must factor as 5 and 1 paired with 3 and 1 as both 5 and 3 do not factor any further. They are prime numbers.

Let's try this:

(5x  +   1) ( 1x + 3)

Both factors must contain an + otherwise something in the given equation would be - when the factors are expanded.

It looks like this works. 5 * 3x + 1x = 16x

How do I solve this
sdas [7]
\bf \textit{difference of squares}
\\ \quad \\
(a-b)(a+b) = a^2-b^2\qquad \qquad 
a^2-b^2 = (a-b)(a+b)\\\\
-------------------------------\\\\
\cfrac{2x}{x^2+2x-24}-\cfrac{x}{x^2-36}\quad 
\begin{cases}
x^2+2x-24\implies (x+6)(x-4)\\
--------------\\
x^2-36\implies x^2-6^2\\
(x-6)(x+6)
\end{cases}

\bf \cfrac{2x}{(x+6)(x-4)}-\cfrac{x}{(x-6)(x+6)}\impliedby 
\begin{array}{llll}
\textit{thus our LCD is}\\
(x-6)(x+6)(x-4)
\end{array}
\\\\\\
\cfrac{[(x-6)2x]~-~[(x-4)x]}{(x-6)(x+6)(x-4)}\implies \cfrac{2x^2-12x-x^2+4x}{(x-6)(x+6)(x-4)}
\\\\\\
\cfrac{x^2-8x}{(x-6)(x+6)(x-4)}

Answer:

  A.  9.6

  B. √92 ≈ 9.59

Step-by-step explanation:

A. 9.6 is a rational number between 9.5 and 9.7. It is rational because it is a terminating decimal.

__

B. √92 is an irrational number between 9.5 and 9.7. It is irrational because it is the square root of an integer that is not a perfect square. Its decimal value is about 9.59.

Create the quadratic function that contains the points (0,2), (1,0), and (3,10). Show all of your work for full credit.
Marina86 [1]

Answer:

y=7/3x²-13/3x+2

Step-by-step explanation:

<u>Determine the value of c:</u>

y=ax²+bx+c

2=a(0)²+b(0)+c

2=c

<u>Substitute (1,0) into the quadratic and create an equation with a and b:</u>

y=ax²+bx+2

0=a(1)²+b(1)+2

0=a+b+2

-2=a+b

<u>Do the same with (3,10) to get a second equation:</u>

y=ax²+bx+2

10=a(3)²+b(3)+2

10=9a+3b+2

8=9a+3b

<u>Set the two equations equal to each other and solve for a and b:</u>

-2=a+b

8=9a+3b

<u>Multiply first equation by 3 and eliminate b to find a:</u>

 -6=3a+3b

- (8=9a+3b)

_______

-14=-6a

14/6=a

7/3=a

<u>Substitute 7/3=a into the first equation:</u>

-2=7/3+b

-2-(7/3)=b

-13/3=b

<u>Final equation:</u>

y=7/3x²-13/3x+2

See the graph for a visual representation
