Evaluate the expression using the given values.

|6x^2 - 4y|; x = 2, y = 5

5 answers

To evaluate the expression |6x^2 - 4y| with x = 2 and y = 5, we substitute these values into the expression and calculate.

|6(2)^2 - 4(5)| = |6(4) - 20| = |24 - 20| = |4| = 4

Therefore, the value of the expression is 4.
Evaluate the following algebraic expression.

3/5z, if z = 10
To evaluate the expression 3/5z with z = 10, we substitute z = 10 into the expression and calculate.

3/5(10) = 3/50

Therefore, the value of the expression is 3/50.
When z = 10, 3/5z =
When z = 10, we can substitute this value into the expression 3/5z.

3/5(10) = 3/5 * 10 = 3 * 10/5 = 30/5 = 6

Therefore, when z = 10, 3/5z = 6.
