Answer:
its 18
Step-by-step explanation:
b/c 6 times 3 is 18
y=-2x+8
y=x-1
Solve y=-2x+8 for y
Substitute -2x+8 for y in y =x-1
y=x-1
-2x+8=x-1
Add -x to both sides
-2x+8+-x=x-1+-x
-3x+8=1
Add -8 to both sides
-3x+8+-8=1+-8
-3x=-9
Divide both sides by -3
-3x/-3=-9/-3
x=3
Substitute 3 for x in y =-2x+8
y=-2x+8
y=(-2)(3)+8
Simplify both sides of the equation
y=2
Answer : y=2 and x=3

Answer:
work is shown and pictured
55% of the Carbon is left in the skull.
If A₀ was the original amount of Carbon, the amount of Carbon that is remaining will be 55% of A₀ which equals 0.55A₀
Using the given equation:
Rounding of to nearest year, we can conclude that the animal was buried 4821 years ago. So option D gives the correct answer
