If you would like to know how many people attended the reunion last year, you can calculate this using the following steps:
125% of last year's attendance is 160 people
125% of x is 160
125% * x = 160
125/100 * x = 160 /*100/125
x = 160 * 100 / 125
x = 128 people (last year)
Result: 128 people attended the reunion last year.
Input 7 for every x so
f(7) = -2 (7)^2 +4
f(7) = -2(49) +4
f(7) = -98 +4
f(7) = -94
Hello!
3x - 32 = -7x + 28
-32 - 28 = -7x - 3x
-60 = -10x
-6 = -x
6 = x
x = 6
I hope this helps you! Have a lovely day!
