Answer:
20% decrease
Step-by-step explanation:
2516/3270 = 0.8 or 80%
This means 80% percent of people showed up again from last year
100-80 = 20
So 20% decrease
Answer:
b = -a
Step-by-step explanation:
Since a and b are equally distant to zero but in opposite directions, a and b are opposites, or additive inverses.
The sum of additive inverses is zero.
a + b = 0
b = -a
The inverse function of f(x) is 
and the domain is x > 6
<h3>How to determine the inverse function?</h3>
The function is given as:
f(x) = x^2 + 6
Rewrite as:
y = x^2 + 6
Swap x and y
x = y^2 + 6
Subtract 6 from both sides
y^2 = x - 6
Take the square root
Rewrite as:
Hence, the inverse function of f(x) is and the domain is x > 6

Answer:
x = 17
Step-by-step explanation:
These are same side interior so they equal different measures. You would write the equation like this.
8x - 9 + 53 = 180 (collect like terms)
8x + 44 = 180 (minus 44 on both sides)
8x = 136 (divide by 8 on both sides)
x = 17
