1 km = 1000 m
so 36km x 1000 = 36000 meters per hour
there are 3600 seconds per hour
36000/3600 = 10 meters per second
10*5 = 50 meters in 5 seconds
Answer: negative, positive
Step-by-step explanation:
Answer:
Sale Price = $34.8 (answer). This means the cost of the item to you is $34.8. You will pay $34.8 for a item with original price of $43.50 when discounted 20%. In this example, if you buy an item at $43.50 with 20% discount, you will pay 43.50 - 8.7 = 34.8 dollars.

There's 24 hours in a day
so 24/100 = 0.24 < that is the percentage per hour
first eating - %10. 0.24x10= 2.4hrs eating
free time - 15% 0.24x15= 3.6hrs of free time
homework - 10% 0.24x10 = 2.4hrs of homework
school - 25% 0.24x25= 6hrs of school
and sleeping = 40% 0.24x40=9.6hrs of sleep
add them(hours) all up and you'll get 24!
Such an equation would be y + 8x = - 25 (standard form) OR y = -8x - 25 (y-intercept form)
Deriving The Answer:
By using the point-slope form of the equation of a line, by knowing the gradient of that line and a point on that line, the equation of this line can be derived.
Now, the point-slope form exists as y - y₁ = m ( x - x₁)
since slope = -8 and the point on the line = (-4 , 7)
Then m = - 8
x₁ = - 4
y₁ = 7
⇒ y - 7 = -8 ( x - (-4))
⇒ y - 7 = -8x - 32
⇒ y + 8x = - 25
