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.
X2 -25 that’s the answer but it’s x squared 2 if that makes sense
Changing the positive/negative happens when you multiply something by -1
-1(x-1) = -x+1
-(x-1) = (-x+1)
3 - (x - 1) = 3 + ( -x + 1) = 4 -x
Answer:
y-intercept = -2
x-intercept = -4
Step-by-step explanation:
y-intercept is the point where x = 0. Hence,
y-intercept = -2
x-intercept us the point where y = 0. Hence,
x-intercept = -4

So we have 5x+15y=45
simplify and undistribute 5 from both sides
5(x+3y)=5(9)
divide both sides by 5
x+3y=9
multiply both sides by 6
6x+18y=54
if it was 6x+18y then the answer is 54
if it was 6x-18y, then I don't know the answer
