Answer:

<em>14 </em>° <em>;</em> <em>83 </em>°

Step-by-step explanation:

( 14x - 1 )° + ( 2x + 2 )° = 97°

14x - 1 + 2x + 2 = 97

16x = 96

x = 6

m∠BCA = ( 2 × 6 + 2 )° = <em>14 </em>°

m∠ABC = ( 14x - 1 )° = <em>83 </em>°

For the first box on the left hand side, the answer is m < 1 + m < 2 = 180 as they are a linear pair

The first box in the right-hand column is "linear pair postulate" as its very similar to the previous line

The second box on the left-hand side is m < 1 + m < 2 = m < 2 + m < 3. Essentially we're doing replacements. Similar to how x+3 = 10 turns into 7+3 = 10 when we plug in x = 7

The second box on the right-hand side is "subtraction property of equality". We subtract "m < 2" from both sides to end up with m < 1 = m < 3

If ln(x^2-x-1)=0 , then x= ?

Umnica [9.8K]

Answer:

x = -1 or 2

Step-by-step explanation:

Taking the antilog, you have the quadratic ...

x^2 -x -1 = 1

x^2 -x -2 = 0 . . . . subtract 1

(x -2)(x +1) = 0 . . . factor

The values of x that make these factors zero are the solutions to the equation.

x = 2 or x = -1

Which polynomial is prime?

finlep [7]

we know that

If the only factors a polynomial are $1$ and itself, then that polynomial is prime.

so

If the polynomial has at least one root (one x-intercept) then the polynomial is not prime

Using a graph tool

<u>case 1) </u>

$x^{3}+ 3x^{2} + 2x+ 6$

see the attached figure N 1

The polynomial has one root-------> the polynomial is not prime

<u>case 2) </u>

$x^{3} + 3x^{2} - 2x - 6$

see the attached figure N 2

The polynomial has three roots-------> the polynomial is not prime

<u>case 3) </u>

$10x^{2}-4x+3x + 6$

$10x^{2} -x + 6$

see the attached figure N 3

The polynomial has zero roots-------> the polynomial is prime

<u>case 4)</u>

$10x^{2}-10x+6x - 6$

$10x^{2} -4x - 6$

see the attached figure N 4

The polynomial has two roots-------> the polynomial is not prime

therefore

<u>the answer is</u>

$10x^{2}-4x+3x + 6$ ------> is prime

The rabbit population in a certain area is 200% of last years population there are 900 rabbits this year how many were there las

Liula [17]

This year there are 900 rabbits which represents 200% of last year's population, means that last year the number of rabbits was:
x = 900 (100/200) = 450 rabbits.
The mathematical expression can be derived by a simple rule of three.
So, for last year the population was 450 rabbits.
