Evaluate the expression using the given values.
|6x^2 - 4y|; x = 2, y = 5
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.
To evaluate the expression |6x^2 - 4y| when x = 2 and y = 5, you need to substitute the given values into the expression and calculate the result.
First, substitute x = 2 and y = 5 into the expression |6x^2 - 4y|:
|6(2)^2 - 4(5)|
Next, simplify the expression inside the absolute value:
|6(4) - 20|
Now, do the arithmetic inside the absolute value:
|24 - 20|
Then, evaluate the subtraction inside the absolute value:
|4|
Finally, take the absolute value of the result:
4
Therefore, when x = 2 and y = 5, the value of the expression |6x^2 - 4y| is 4.
