Answer:
X-intercepts: (-3,0) and (5,0)
Y-intercept: (0,-15)
Step-by-step explanation:
x^2 - 2x - 15
(x + 3) (x -5)
x +3 = 0
x = -3. (-3, 0)
x - 5 = 0
x = 5. (5, 0)
Answer:
16 : 25
Step-by-step explanation:
The ratio of girls : boys = 320 : 500
To simplify divide both parts by 10
320 : 500 = 32 : 50 ← now divide both parts by 2
32 : 50 = 16 : 25 ← in simplest form
6 = x + 2
Subtract 2 from both sides
6 - 2 = x + 2 - 2
4 = x
