Rewrite the hyperbolic equation 4y^2 -9x^2 +54x-8y-113=0

The mean of a set of data is -3.82 and its standard deviation is 2.31. find the z score for a value of 3.99.

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =
