Log2 ( x2 – 3x ) < 2

Mathematics
1 answer:
UNO [17]4 years ago
4 0

cause we know that the base is more than 1 , we can do this way:

{x}^{2}  - 3x < 4

so we can answer it:

x^2_3x-4<0 x is -1 or -4 to make it 0

so after obtaining the signs of equation we can have:

x=(-4,-1)

cluponka [151]

<em>Answer: There are 5 trumpet players and 15 saxophone player</em>


<em>Step-by-step explanation: Let a be the number of trumpet players </em>

<em>Let b be the number of saxophone players </em>

<em>--------------------- </em>

<em>(1) a = b-10 </em>

<em>(2) b =3a </em>

<em>---------------- </em>

<em>Substitute  </em>

<em>(2) into (1) </em>

<em>(1) a =3a-10 </em>

<em>(1) 2a =10  </em>

<em> </em>

<em> (1) a = 5and </em>

<em>(2) b = 3(5)(2)  </em>

<em>b =  15 </em>

PRESS ON THE PHOTO!! ONLY NUMBER 10 PLEASE
marta [7]

Answer:

B: T = ½R

Step-by-step explanation:

From the given graph, we see the following;

When T = 2, R = 4

When T = 3, R = 6

When T = 4, R = 8

When T = 5, R = 10

Looking at those values, we can see a pattern where R is always equal to 2T.

Or T = ½R

Thus, option B is the answer.

What is the quotient of (x3 - 3x2 + 5x – 3) = (x - 1)?
IRINA_888 [86]

Note: Consider "÷" sign instead of "=".

Given:

(x^3-3x^2+5x-3)\div (x-1)

To find:

The quotient.

Solution:

We have,

(x^3-3x^2+5x-3)\div (x-1)

It can be written as

=\dfrac{x^3-3x^2+5x-3}{x-1}

Splitting the middle terms, we get

=\dfrac{x^3-x^2-2x^2+2x+3x-3}{x-1}

=\dfrac{x^2(x-1)-2x(x-1)+3(x-1)}{x-1}

Taking out the common factor (x-1), we get

=\dfrac{(x-1)(x^2-2x+3)}{x-1}

Cancel the common factors.

=x^2-2x+3

The quotient is x^2-2x+3.

Therefore, the correct option is D.
