100% of the price = $400
x % of the price = $320
we need to find x

using a proportion
100 : 400 = x : 320
100 * 320 = 400 * x
32000 = 400x
x = 32000 / 400
x = 80

That means the new price is 80% of the previous price.
100% - 80% = 20%
and based on this we can make a conclusion that the discount was 20%

I hope it is clear to you, feel free to ask anything about it :)

20% because 20% is $60 and you can keep adding $60 4 more times so there's 5 of $60

Question 1 of 9
dimaraw [331]

Answer:

B

Step-by-step explanation:

The zeros ( where the graph crosses the x- axis ) are x = 2 and x = 6

The corresponding factors are (x - 2) and (x - 6) and the equation is the product of the factors, so

y = (x - 2)(x - 6) ←  expand using Foil

y = x² - 8x + 12 → B

7. point A(-2, 7); parallel to the line y = - 3x - 4
aniked [119]

Answer:

y=-3x+1

Step-by-step explanation:

plug in point into x and y, replace -4 as a +b(or any other variable to represent y intercept)

therefore,

7=-3(-2)+b

7=6+b

1=b

y=-3x+1
