Hi there!

I'm guessing you want to know what the equation of the slope-intercept line is.

The general equation for the slope-intercept line looks like this:

y = mx + b

Where "m" is the slope and "b" is the y-intercept.

Since we know what the slope is and we have the coordinates of a point, you can replace the slope and the value of the coordinates "x" & "y" in the equation and solve for "b" in order to find the whole equation :

y = mx + b

-1 = -1/2(10) + b

subtract "b" from each side of the equation

-1 - b = -1/2(10)

Add 1 to each side of the equation

-b = -1/2(10) + 1

-b = -5 + 1

-b = -4

Divide each side of the equation by -1

b = 4


Since you now know the value of "b" you can go ahead and write the slope-intercept equation with the slope in it and the y-intercept value also (b) :

y = -1/2 + 4


There you go! I really hope this helped, if there's anything just let me know! :)

Answer: 2 inches, 3 inches, or 3.125 and 2.083


Explanations:
The simplest way is to take 20% of the 2.5 inches and go that much above & below 2.5 inches.

2.5 x 20% = 2.5 x 0.20 = 0.5

So 2.5 - 0.5 = 2 inches was predicted
And 2.5 + 0.5 = 3 inches was predicted.

The more complicated way is to see number + 20% of that number = 2.5, and what number - 20% = 2.5.

Which solution sounds more like what you’re doing in class right now?

If it’s the more complicated way:

0.8x = 2.5 (80% of the predicted rain value equals 2.5)
x = 3.125 inches was predicted

1.2x = 2.5 (120% of the predicted rain value equals 2.5)
x = 2.083 inches was predicted

Sorry, this is probably confusing. Let me know what questions you have.

rosijanka [135]

Answer:

(x - 8)(x + 3)

Step-by-step explanation:

x² - 5x - 24

Consider the factors of - 24 which sum to give the coefficient of the x- term (- 5)

The factors are - 8 and + 3 , since

- 8 × + 3 = - 24 and - 8 + 3 = - 5

Use these factors to split the x- term

x² - 8x + 3x - 24 ( factor the first/second and third/fourth terms )

= x(x - 8) + 3(x - 8) ← factor out (x - 8) from each term

= (x - 8)(x + 3) ← in factored form
