Answer:

c ( x - 5 ) ( x + 3 ) ( x - 1 )

Step-by-step explanation:

if you multiply the first two brackets you would get x² - 2 - 15, for example x × x will give you x² x × 5 will give you 5x and so on ( basically you need to use the FOIL method )

to get x² + 2x - 3 multiply the second and third brackets with each other just like how you did for the first one.

I'm not sure if that's what you wanted...

Buying one movie ticket online costs $16.50. Two tickets cost $30.50. Assuming that the relationship is linear, use the drop dow

HACTEHA [7]

Answer:

$C(n)=14n+2.50$

Step-by-step explanation:

Let

n -----> number of tickets

C ----> represent the cost of buy n tickets online

we have the ordered pairs

(1,16.50) and (2,30.50)

<em>Find out the slope of the linear equation</em>

The formula to calculate the slope between two points is equal to

$m=\frac{C2-C1}{n2-n1}$

substitute the values

$m=\frac{30.50-16.50}{2-1}$

$m=14$

<em>Find the equation of the line in slope intercept form</em>

$C=m(n)+b$

we have

$m=14$

$point(1,16.50)$

substitute

$16.50=14(1)+b$

$b=16.50-14$

$1b=2.50$

substitute

$C(n)=14n+2.50$

The domain of the function is all positive integers (whole numbers) including zero

{0,1,2,3,4,...}

-2(x + 2) = -2x ++ 5x -1

earnstyle [38]

Answer:

-⅗ = x

Step-by-step explanation:

Here is what you get when you distribute the -2 on the left side of the equivalence symbol and combine like-terms on the right side of the equivalence symbol:

-2x - 4 = 3x - 1

Here is the solution:

-2x - 4 = 3x - 1

-3x -3x

----------------

-5x - 4 = -1

4 +4

----------------

-5x = 3

----- -----

-5 -5

x = -⅗

Dragon drop each expression two correctly classify it as having a positive or negative product

ioda

Step-by-step explanation:

We multiply it to find the product

positive times positive = positive

positive times negative = negative

negative times positive = negative

negative times negative = positive

$(-\frac{1}{3})(-\frac{1}{3})= \frac{1}{9}$

Negative and negative is positive , so product is positive

$(-\frac{1}{3})(\frac{1}{3})= -\frac{1}{9}$

Negative and positive is negative , so product is negative

$(\frac{1}{3})(-\frac{1}{3})= -\frac{1}{9}$

positive and negative is negative , so product is negative

$(\frac{1}{3})(\frac{1}{3})= \frac{1}{9}$

positive and positive is positive , so product is positive
