Answer:
80% decrease
Step-by-step explanation:
A percentage change can be calculated using ...
percent change = ((new value)/(old value) -1) × 100%
= (16/80 -1) × 100%
= -0.80 × 100% = -80%
The minus sign indicates the change was a decrease.
From Saturday to Tuesday, customers decreased 80%.

Answer:
7y-3x-8z
Step-by-step explanation:
(3y+4y)+(2x-5x)-8z
7y+(2x-5x)-8z
7y-3x-8z
Answer:
y = 3x + 5
Step-by-step explanation:
slope:
11 - (-1) / 2 - (-2) = 12/4 = 3
slope intercept form is y = mx + b, so right now you have m = 3:
y = 3x + b
now, since you know x = -2 and y =-1 is a solution, you can plug those values in:
-1 = 3 * -2 + b
-1 = -6 + b
5 = b
This means the equation is y = 3x + 5
