varies directly means $\frac{y}{x} = k$

inserting y = -18 and x = 3 ⇒ $\frac{-18}{3} = k$ ⇒ -6 = k

next, insert k = -6 into the varies directly equation and solve for y. y = -6x

Exponential Rule [Multiplying]: $\displaystyle b^m \cdot b^n = b^{m + n}$
Exponential Rule [Dividing]: $\displaystyle \frac{b^m}{b^n} = b^{m - n}$

Step-by-step explanation:

Step 1: Define

$\displaystyle \frac{3^3 \cdot 3^3}{3^4}$

Step 2: Simplify

[ER] Multiply: $\displaystyle \frac{3^{3+3}}{3^4}$
Add Exponents: $\displaystyle \frac{3^6}{3^4}$
[ER] Divide: $\displaystyle 3^{6 - 4}$
Subtract Exponents: $\displaystyle 3^2$

Find the determinant of the matrix.

Jobisdone [24]

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)
