Answer:
Option (2)
Step-by-step explanation:
1). If two lines have the same slope, lines are defined as parallel.
m₁ = m₂
2). If the multiplication of the slopes of two lines is (-1), lines will be perpendicular.
m₁ × m₂ = (-1)
Line 1 : It passes through two points (-2, 10) and (1, 1).
Slope of the line 1 = 
= 
= 
m₁ = 
Line 2 : It passes through two points (-2, 8) and (2, -4).
Slope of the line 2 =
= 
= 
m₂ = -3
Since, m₁ × m₂ = 
= (-1)
Therefore, given lines are perpendicular to each other.
Option (2) is the correct option.
Answer:
x = 2
Step-by-step explanation:
5(x-4) =-10
Distribute 5 by multiplying x and -4 by 5
5x - 20 = -10
Add 20 to both sides
5x - 20 + 20 = -10 + 20
5x = 10
Divide both sides by 5
5x ÷ 5 = 10 ÷ 5
x = 2

Answer:
1.14 products per hour of labor
Step-by-step explanation:
To calculate the daily productivity would be the amount of products per hour of labor.
That is: 400 products / 350 hours of labor, and that is approximately 1.14 products per hour of labor.
Which means that for every hour of labor, 1.14 products are produced in one day, which would be a factor of productivity.

Answer:
987 ft.
Step-by-step explanation:
We can solve this with an equation.
Since she has 5 rolls of 99 feet long blue streamer, then she has 5*99=495 feet of blue streamer
Since she has 9 rolls of 88 feet long blue green, then she has 9*88=792 feet of blue green
To find the total, we can add them up and get 495+792=987
