tan θ=−4/7, and 270°<θ<360°
θ is in 4th quadrant
sec θ = 8.06 / 7 = 1.15
14. 74 fl oz > 8 cups (8 oz=1 c)
15. 12 c = 3 qt (4c=1qt)

Answer:
B. 3/9 = 4/12 = 1/3
Step-by-step explanation:
I calculated it logically
Answer:
I solve it by substitution
y=x^2+4x
-x^2+9x+(x^2+4x)+13=0
13x+13=0
13x=-13
x= -13/13
x= -1
y=x^2+4x=1-4
y= -3
