Answer:

slope = $\frac{1}{2}$

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 ) = (- 8, 0) and (x₂, y₂ ) = (4, 6) ← 2 points on the line

m = $\frac{6-0}{4+8}$ = $\frac{6}{12}$ = $\frac{1}{2}$

State the degree and end behavior of f(x) = 2x3 – 3x – x2 + 1. Explain or show<br> your reasoning

Olin [163]

Answer:

Answer:

As x→∞ , f(x)→-∞

x→-∞ , f(x)→∞

Step-by-step explanation:

End behavior is determined by the degree of the polynomial and the leading coefficient (LC).

The degree of this polynomial is the greatest exponent, or

The leading coefficient is the coefficient of the term with the greatest exponent, or

For polynomials of even degree, the "ends" of the polynomial graph point in the same direction as follows.

Even degree and positive LC:

As x→∞ , f(x)→∞ As x→∞, f(x)→∞

Even degree and negative LC:

As x→−∞ , f(x)→−∞

x→∞ , f(x)→−∞

Christian has a cookie recipe that yields four dozen cookies and calls for 2 1/4 cups white sugar and 3/4 cup brown sugar.cif ch

Paha777 [63]

The ingredients given are for 4 dozen cookies; however, Christian only want to make one dozen, meaning he requires only 1/4 the ingredients.

1/4 of 2 1/4 cups of while sugar is found the following way.

First, we write 2 1/4 as an improper fraction

$2\frac{1}{4}=2+\frac{1}{4}=\frac{9}{4}$

1/4 of this is

$\frac{9}{4}\times\frac{1}{4}=\frac{9}{16}$

Hence, Christian requires 9/16 cups of white sugar.

Similarly, the 1/4 of 3/4 cups of brown sugar is

$\frac{1}{4}\times\frac{3}{4}=\frac{3}{16}$

Hence, Chrisitan requires 3/16 cups of brown sugar.

Therefore, the total cups of sugar required is the sum of

$\frac{3}{16}+\frac{9}{16}=\frac{12}{16}=\frac{3}{4}$

3/4 cups of sugar.
