Answer:

slope = 2

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = - $\frac{1}{2}$ x + 5 ← is in slope- intercept form

with slope m = - $\frac{1}{2}$

Given a line with slope m then the slope of a line perpendicular to it is

$m_{perpendicular}$ = - $\frac{1}{m}$ = - $\frac{1}{-\frac{1}{2} }$ = 2

Answer:

6 bouquet

Step-by-step explanation:

To obtain the greatest number of bouquet she could have ;

Obtain the greatest common factor of 18 and 24

Factors of 18 : 1 , 2, 3, 6, 9, 18

Factors of 24 : 1, 2, 3, 4, 6, 8, 12, 24

The greatest factor commo to both 18 and 24 is 6.

Hence, the greatest number of bouquet she could have is 6.

1/(x+1) - 1/(x+2) = 1/2

katen-ka-za [31]

Please include the instructions; I assume your job is to find the value of x.

<span>1/(x+1) - 1/(x+2) = 1/2 would better be written as

1 1 1
</span><span>-------- - ------------ = ----
x+1 x+2 2

Identify the LCD. It is (x+1)(x+2)(2). Mult. all 3 terms of the equation by this LCD:

2(x+2) - 2(x+1) = 2(x+1)(x+2)

We can factor out the 2 from all terms:

x+2 - x - 1 = x^2 + 3x + 2

Let's move all terms from the left to the right side:

0 = x^2 + 3x + 2 - x - 2 + x + 1

Then x^2 + 3x + 1 = 0. This is a quadratic with a=1, b=3 and c=1.

What is x?

-3 plus or minus sqrt( 9-4(1)(1) ) -3 plus or minus sqrt(5)
x = --------------------------------------------- = ---------------------------------
2 2

I rather expected to obtain an integer value for x.

Why don't you give this problem a try yourself? Suggestion: First mult. every term by 2. This will give you:

2 2
------- - ------- = 1 and this may be slightly easier to work with. Please
x+1 x+2 give it a try: try to find x that satisfies this equation.
Important: note that x cannot equal either -1 or -2.
