Answer:
f(x) = x² - 9
Step-by-step explanation:
Given x = a is a zero of the polynomial f(x) then (x - a) is a factor
Given zeros are x = 3 and x = - 3, then corresponding factors are
(x - 3) and (x - (- 3) ), that is
(x - 3) and (x + 3)
The function is then the product of the factors, that is
f(x) = (x - 3)(x + 3) ← expand using FOIL
f(x) = x² - 9

Answer:
i think it would be $80 (brainliest??)
Step-by-step explanation:
jane had a total of $200 BEFORE she spent on 2 games
1. $40
2. $40
3. $40
4. $40
5.$40
2 games = $80
3 games = $120 (money she had left)
Answer:
Step-by-step explanation:
lets pick 2 points on the line....(6,5) and (10,3)
slope = (y2 - y1) / (x2 - x1)
(6,5)....x1 = 6 and y1 = 5
(10,3)....x2 = 10 and y2 = 3
now we sub
slope = (3 - 5) / (10 - 6) = -2/4 = -1/2
now we use y = mx + b
slope(m) = -1/2
u can use either of ur points...I will use (6,5)...x = 6 and y = 5
now we sub and find b, the y int
5 = -1/2(6) + b
5 = -3 + b
5 + 3 = b
8 = b
so ur equation is : y = -1/2x + 8 <===
The dependent variable is 5 and the independent is 15
