Answer:

A

Step-by-step explanation:

Calculate the slope m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (- 3, 4 ) and (x₂, y₂ ) = (2, - 1 )

m = \frac{-1-4}{2-(-3)} = \frac{-5}{2+3} = \frac{-5}{5} = - 1 → A

P(x)=x^3+2x^2-4x-8 how do you factor this polynomial function
Wewaii [24]
<h2>Steps:</h2>

So for this, I will be factoring by grouping. Firstly, factor x³ + 2x² and -4x - 8 separately. Make sure that they have the same quantity inside of the parentheses:

p(x)=x^2(x+2)-4(x+2)

Now we can rewrite it as:

p(x)=(x^2-4)(x+2)

However, we aren't finished factoring yet. The first factor, x² - 4, can be factored further using the difference of squares. The difference of squares goes by the formula here: x^2-y^2=(x+y)(x-y) . In this case:

x^2-4=(x+2)(x-2)\\p(x)=(x+2)(x-2)(x+2)

<h2>Answer:</h2>

<u>In short, the answer is p(x)=(x+2)(x-2)(x+2)\ \textsf{OR}\ p(x)=(x-2)(x+2)^2</u>

A sum of Rs.750 is in the form of denominations of Rs.50 and Rs.100. If the number of 100-rupee notes is twice the number of 50-
Naddik [55]

Answer:

100 rupee notes= 6, 50 rupee notes=3

Step-by-step explanation:

3 x 50 = 150

6 x 100 = 600

600 + 150 = 750

and 3 x 2 = 6, so the amount of 100 rupee notes are twice the amount of 50 rupee notes.

Hope this helps :)
