Answer:
1. 
2. Required factors: (x - 10) (x - 13)
x = 10, x = 13
Step-by-step explanation:
1.
Graph is intersecting x-axis at points (5, 0) & (11, 0)
Hence, x = 5 & x = 11 are zeroes of the function.
So, (x - 5) & (x - 11) are factors of the quadratic function:
Therefore, required function is:
2.
Plug y = 0
So, x - 10 = 0, x - 13 =0
x = 10, x = 13
Answer: x = 6, y = 1, coordinate = (6, 1)
<u>Step-by-step explanation:</u>
Note that f(x) = y
so when given f(6) = 1
↓ ↓
x=6 y=1
(y+5)(y+6+5) = 187
y2+16y+55 = 187
y2 +16y - 132 =0
y = 6 or -22(rejected)
so 6 years old

Answer:
<h2>The option B and D are the equations.</h2>
Step-by-step explanation:
Let, the total number of students are x.
The number of students having the ticket is 
.
It is given that the number is 20.
Hence, 
.
Option B is the equation.
Option D is also the same.
The difference is just, the variable is wriiten in the other side.
