Answer:

The answer is -7. This equation only has one solution. It makes the equation -2 = -2.

For the second part, you can use a number like 7 and then that would make it be 2 = -2. Hope this Helps!

Answer:

$[B]=2$

Step-by-step explanation:

$B=\left[\begin{array}{ccc}3x-5&-3+2y\\11-3x&2y-5\end{array}\right]$

With $x=3$ and $y=4$

$B=\left[\begin{array}{ccc}3(3)-5&-3+2(4)\\11-3(3)&2(4)-5\end{array}\right]$

$B=\left[\begin{array}{ccc}9-5&-3+8\\11-9&8-5\end{array}\right]$

$B=\left[\begin{array}{ccc}4&5\\2&3\end{array}\right]$

solving the determinant of matrix B

$[B]=\left[\begin{array}{ccc}4&5\\2&3\end{array}\right]=(4.3-5.2)=(12-10)=2$

4(3xy^4)^3/(2x^3y^5)^4

myrzilka [38]

Answer:

$\frac{4\left(3xy^4\right)^3}{\left(2x^3y^5\right)^4}=\frac{27}{4x^9y^8}$

Step-by-step explanation:

Given the expression

$\:\:\frac{4\left(3xy^4\right)^3}{\left(2x^3y^5\right)^4}$

solving the expression

$\:\:\frac{4\left(3xy^4\right)^3}{\left(2x^3y^5\right)^4}=4\cdot \:\frac{\left(3xy^4\right)^3}{\left(2x^3y^5\right)^4}$

$=4\:\frac{27x^3y^{12}}{16x^{12}y^{20}}$

$=4\cdot \frac{3^3}{2^4x^9y^8}$

The multiply fractions are defined as

$\:a\cdot \frac{b}{c}=\frac{a\:\cdot \:b}{c}$

so the expression becomes

$=\frac{3^3\cdot \:4}{2^4x^9y^8}$

$=\frac{3^3\cdot \:2^2}{2^4x^9y^8}$

$=\frac{3^3}{2^2x^9y^8}$

Refining

$=\frac{27}{4x^9y^8}$

Therefore,

$\frac{4\left(3xy^4\right)^3}{\left(2x^3y^5\right)^4}=\frac{27}{4x^9y^8}$
