-3x+80>20
You then move the 20 to right hand side
-3x>20-80
So 20-80 = -60
-3x>-60
You then divide them

= x < 20

What is the product? (-2d^2+s)(5d^2-6s)

Ulleksa [173]

(-2d^2+s)(5d^2-6s)
= (-2d^2*5d^2 + s*5d^2 -2d^2*-6s + s*-6s
= -10d^4 + 5sd^2 + 12sd^2 - 6s^2
=-10d^2 + 17sd^2 - 6s^2
This is the final result

What is the slope of a line that is parallel to the Line shown?

Vikki [24]

Answer:

2/3

Step-by-step explanation:

The slope of a line can be computed as:

$m=\frac{\Delta y}{\Delta x}$

where

$\Delta y = y_2-y_1$ is the increment along the y-direction

$\Delta x = x_2 - x_1$ is the increment along the x-direction

We can choose the following two points to calculate the slope of the line shown:

(0,1) and (3,3)

Therefore, the slope of the line is

$m=\frac{3-1}{3-0}=\frac{2}{3}$

Two lines are said to be parallel if they have same slope: therefore, a line parallel to the one shown should also have slope of 2/3.
