Answer:
yes
Step-by-step explanation:
this number is a decimal
The slope formula is y2-y1/x2-x1 so 5-(-1) =6 Then. 1-(-1)=2 so 6/2. =3. THE ANSWER IS 3
5 equals the whole number 5?
Answer:
x = 39.1
Step-by-step explanation:
mean = average off all the numbers =
sum of the numbers / amount of numbers.
35 = sum of the #'s / # of #'s
35 = 100.9 + x / 4
35 × 4 = 100.9 + x / 4 × 4
140 = 100.9 + x
140 – 100.9 = 100.9 + x – 100.9
39.1 = x
x = 39.1
![(x-5)(x^2-x-4) =x^3-6x^2+x+20](https://tex.z-dn.net/?f=%28x-5%29%28x%5E2-x-4%29%20%3Dx%5E3-6x%5E2%2Bx%2B20)
Step-by-step explanation:
Given polynomials are:
![x^2-x-4\\and\\x-5](https://tex.z-dn.net/?f=x%5E2-x-4%5C%5Cand%5C%5Cx-5)
Both polynomials have to be multiplied. We will use distributive property for the said purpose
So,
![(x-5)(x^2-x-4)\\=x(x^2-x-4)-5(x^2-x-4)\\=x^3-x^2-4x-5x^2+5x+20](https://tex.z-dn.net/?f=%28x-5%29%28x%5E2-x-4%29%5C%5C%3Dx%28x%5E2-x-4%29-5%28x%5E2-x-4%29%5C%5C%3Dx%5E3-x%5E2-4x-5x%5E2%2B5x%2B20)
Combining alike terms
![=x^3-x^2-5x^2-4x+5x+20\\=x^3-6x^2+x+20](https://tex.z-dn.net/?f=%3Dx%5E3-x%5E2-5x%5E2-4x%2B5x%2B20%5C%5C%3Dx%5E3-6x%5E2%2Bx%2B20)
Hence,
![(x-5)(x^2-x-4) =x^3-6x^2+x+20](https://tex.z-dn.net/?f=%28x-5%29%28x%5E2-x-4%29%20%3Dx%5E3-6x%5E2%2Bx%2B20)
