Answer:
Step-by-step explanation:
The functions are given f and g using coordinates.
Whenever we will ask for f(a), we look for "a" in the x coordinate of the function f and find the corresponding value. THAT IS THE ANSWER.
If we ask for g(b), we look for "b" in the x coordinate of the function g and find the corresponding value. THAT IS THE ANSWER.
So,
B=60 ..

Answer:
Step-by-step explanation:
The given quadratic equation is expressed as
x² - 6x - 40 = 0
The equation is already in the standard form of ax² + bx + c
The general formula for solving quadratic equations is expressed as
x = [- b ± √(b² - 4ac)]/2a
From the equation given,
a = 1
b = - 6
c = - 40
Therefore,
x = [- - 6 ± √(- 6² - 4 × 1 × - 40)]/2 × 1
x = [- 6 ± √(36 - - 160)]/2
x = [- 6 ± √196]/2
x = (- 6 + 14)/2 or x = (- 6 - 14)/2
x = 8/2 or x = - 20/2
x = 4 or x = - 10
Answer:
124 child tickets, and 78 adult tickets
Step-by-step explanation:
x=child
y= adult
x+y=202
10x+6y=1708
Multiply eq1 by 6
6x+6y=1212
-4x=-496
x=124
y=78
Hope this helps plz mark brainliest :D
