Which of the following is the product
choli [55]

Answer:

  \text{\bf{A.}}\quad\dfrac{3x^2}{x^2-6x-7}

Step-by-step explanation:

As with multiplying any rational expressions, the numerator of the result is the product of the numerators, and the denominator of the result is the product of the denominators.

\dfrac{3x}{x+1}\cdot\dfrac{x}{x-7}=\dfrac{(3x)(x)}{(x+1)(x-7)}=\dfrac{3x^2}{x^2-6x-7}

_____

The denominator product is found using the distributive property. Each of the terms of one factor is multiplied by the other factor.

(x+1)(x-7)=x(x-7)+1(x-7)\\\\=x^2-7x+1x-7=x^2-6x-7

Which of the following is a point slope equation of a line that passed through the points (10,5) and (4-7)
levacccp [35]

Answer:

<h2>y - 5 = 2(x - 10)</h2>

Step-by-step explanation:

The point-slope form of an equation of a line:

y-y_1=m(x-x_1)

m - slope

(x₁, y₁) - point

The formula of a slope:

m=\dfrac{y_2-y_1}{x_2-x_1}

We have the points (10, 5) and (4, -7). Substitute:

m=\dfrac{-7-5}{4-10}=\dfrac{-12}{-6}=2

y-5=2(x-10)
