Find the slope of the line that passes through each pair of points (13,-3),(-5,-5)

PIT_PIT [208]

Answer:

$\boxed{\bold{\frac{1}{9} }}$

Explanation:

(13,-3), (-5,-5)

Find The Slope:

$\bold{\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}}$

$\bold{\left(x_1,\:y_1\right)=\left(13,\:-3\right),\:\left(x_2,\:y_2\right)=\left(-5,\:-5\right)}$

$\bold{m=\frac{-5-\left(-3\right)}{-5-13}}$

$\bold{ \ m \ = \ \frac{1}{9} }$

Find the following products:

baherus [9]

Answer:

i. x^2 – 1

ii. x^3 – 1

iii. x^4 - 1

Step-by-step explanation:

Products are obtained by multipliyng each left term by each rigth term as follows:

i. (x- 1)(x+ 1) = (x^2 – x + x - 1) = x^2 – 1 (equal terms with opposite sign substracts and the result is 0)

ii. (x- 1)(x^2 + x + 1) = (x^3 – x^2 + x^2 – x + x – 1) = x^3 – 1

iii. (x- 1)(x³ + x² + x + 1) = (x^4 – x^3 + x^3 – x^2 + x^2 – x + x – 1) = x^4 - 1
