First table
y = -4x +10
if x = 8, y = -4(8) + 10 = -22
second table
y =-3x + 2
if x = 8, y = -3(8) + 2 = -22
answer
D (8, –22) <span>is the solution to this system</span>
Answer:
Step-by-step explanation:
One of the methods is to first split the face and the denominator of the fraction into first bases:
Let's simplify:
Sin θ=sqrt(1-<span>cos^2 θ)
</span>sin θ=sqrt[1-(5/13)^2]
sin θ=sqrt[1-(5)^2/(13)^2]
sin θ=sqrt[1-25/169]
sin θ=sqrt[(169-25)/169]
sin θ=sqrt(144/169)
sin θ=sqrt(144)/sqrt(169)
sin θ=12/13
Answer: Second option 12/13

Let x the age of John
Amy's age = x + 9
from question, we get,
John's age + Amy's age = 23
x+(x+9)= 23
=> x + x + 9 = 23
=> 2x = 23 - 9
=> x = 14/2
=> x = 7
