lesya692 [45]
For this case, the first thing we must do is identify the linear expressions.
 first linear expression = y1 = x
 second linear expression = y2 = 5
 We have then that the difference of the second with respect to the first is:
 y2-y1 = 5-x
 Answer:
 
The difference when the second line is here is subtracted from the first is:

Write a equation for (-6, -3)
Vlad [161]

<u>Answer</u>:

equation: y = x/2

<u>Explanation</u>:

let the points be  (-6, -3) ,  ( 0, 0)

slope: \frac{y2-y1}{x2-x1}

         : \frac{0--3}{0--6}

         : \frac{1}{2}

Equation using:

y - y1 = m ( x - x1 )

y - - 3 = 1/2( x - - 6 )

y + 3 = x/2 + 3

y\\ = \frac{x}{2}

What is the factored form of 5x2 − 18x − 8? (5x + 4)(x + 2) (5x + 2)(x − 4) (5x + 1)(x + 8) (5x + 1)(x − 8)
olya-2409 [2.1K]
Hello! So, this question is in the form of ax² - bx - c. First thingd first, let's multiply a and c together. c = -8 and a = 5. -8 * 5 is -40. Now, let's find two factors that have a product of 40, but a sum of 18. If you list the factors, you see that 2 and 20 have a product of 40, but  2 - 20 is -18. The factors we will use are -2 and 20.

How to factor it:

For this question, you can use something called a box method and factor it by finding a factor of each column and row. Just make 4 boxes and put 5x² on the top left and -40 on the bottom left box. Put 2x on the top right box and -20x on the bottom left box. Now, factor out for each row and column. The factors should be 5x + 2 for the top part and x - 4 for the side. It should look like (5x + 2)(x - 4). Let's check it. Solve it by using the FOIL method and you get 5x² - 20x + 2x - 8. Combine like terms and you get 5x² - 18x - 8. There. The answer is B: (5x + 2)(x - 4)

Note: The box method may be challenging at first, but it can be really helpful on problems like these.
