Matrices X and Y both measure 2x2 and are inverses of each other. Which matrix represents their product?

Karolina [17]

Answer:

When a matrix is multiplied by its inverse the result will be the identity matrix. If we multiply two matrix with the same size, the resulting matrix will have the same dimension.

Therefore, if we multiply the matrices X and Y we will get a 2x2 identity matrix, as follows:

$\left[\begin{array}{ccc}1&0\\0&1\\\end{array}\right]$

Please help ASAP!!!!!!!!!! Which expression is equivalent to the following complex fraction? 1 + StartFraction 1 Over y EndFract

sveticcg [70]

Answer:

$(B)\dfrac{y+1}{y-1}$

Step-by-step explanation:

We are to find an equivalent expression for:

$\dfrac{1+\frac{1}{y} }{1-\frac{1}{y}}$

Step 1: Combine the terms in the numerator into one fraction. Do the same for the denominator.

$=\dfrac{\frac{y+1}{y} }{\frac{y-1}{y}}$

Step 2: Write on a straight line and simplify

$=\dfrac{y+1}{y} \div \dfrac{y-1}{y}\\=\dfrac{y+1}{y} \times \dfrac{y}{y-1}\\=\dfrac{y+1}{y-1}$

The correct option is B.
