Original price of the item: $40
Discount percent off: 25% so convert 25% into decimal place
25/100=0.25
Amount saved (discount): 0.25 x 40 = $10
Sale/Discounted price: $30
Therefore, Rica pay $30 for the video game.
Answer:
30 minutes
Step-by-step explanation:
300/10= 30
Hope this helps! :)
When x = 0,
4(0) - 2y = 8
-2y = 8
y = -4
When x = 1,
4(1) - 2y = 8
-2y = 8 - 4 = 4
y = -2
When x = 2,
4(2) - 2y = 8
-2y = 8 - 8 = 0
y = 0
The required solutions are (0, -4), (1, -2), (2, 0)
Since the graph is a straight line, we know that this equation follows some sort of y = mx + b format.
Let's take the points that are on the axes (-4,0) and (0,-3)
use them to find the slope = (0 - (-3))/(-4 - 0) = 3/(-4) = -3/4
this is our m in the general equations above
we now have y = (-3/4)x + b
b is the y-intercept which is where x = 0 we already have that point in (0,-3)
plug the -3 in for b to give as a final answer:
y = (-3/4)x - 3
