Answer: A. y = -8x + 4 because the slope goes in front with the x (-8x) and the y intercept is after the slope (4)
Answer:
-276
Step-by-step explanation:
We'll use the method of cofactors. Use the coefficient +6 for
9 2
8 10
This gives you one third of the solution: 6 {(9)·(10) - (8)(2) }, or 444.
Next, use the coefficient 9, taking care to change the sign to -9 as follows:
9 1
-9 | | = -9(90 - 8) = -9(82) = -738
8 10
Finally with +2 as y our coefficient, evaluate the cofactor
9 1
9 2
ending up with
+2(18-9) = +2(9) = 18
Finally add these three results together:
+444 - 738 + 18 = -276
This, the determinant, D, is -276 (the fourth answer choice)

Answer:
3 years
Step-by-step explanation:
Let y = number of orangutans, and let x = number of years.
For each study, the population, y, after x years is:
First study:
y = 784 - 25x
Second study:
y = 817 - 36x
We set the populations equal and solve for x, the number of years.
784 - 25x = 817 - 36x
Add 36x to both sides. Subtract 784 from both sides.
11x = 33
Divide both sides by 11.
x = 3
