Answer:
r1= -3
r2= (11/2)
Step-by-step explanation:
5-4r=17
-4r=17-5
-4r=12
r=13
and
5-4r=-17
-4r=-22
r= 11/2
To get x intercept:
let y=0,x➖12=0,x=12
so x intercept point (12,0)
To get y intercept:
let x=0,3y➖12=0,y=4
so y intercept point (0,4)
3+1=h i beev this because you are adding the amount of adults to children then that would get you to h
Answer:
11.59x² -7.66x + 9.85

11.59x² -7.66x + 9.85
A + 12.5 = 20
- 12.5 -12.5
