If x = 6 and y = 4, what is the value of the expression 2y – x 2?
Substituting the given values, we have:
2(4) - 6^2 = 8 - 36 = -28
Therefore, the value of the expression is -28.
To find the value of the expression 2y - x^2, we'll substitute the given values of x and y.
Given:
x = 6
y = 4
Now, let's substitute these values into the expression:
2(4) - 6^2
First, let's solve the exponent:
6^2 = 6 * 6 = 36
Now, substitute the value:
2(4) - 36
Multiply the numbers:
8 - 36
Finally, subtract:
-28
Therefore, the value of the expression 2y - x^2, when x = 6 and y = 4, is -28.
To find the value of the expression 2y – x² when x = 6 and y = 4, we need to substitute these values into the expression and then simplify it.
First, let's substitute the value of x into the expression. We have x = 6, so the expression becomes:
2y – (6)²
Next, let's simplify the exponent:
2y – 36
Now, substitute the value of y, which is 4:
2(4) – 36
Finally, let's simplify the expression:
8 – 36
Therefore, the value of the expression 2y – x² when x = 6 and y = 4 is -28.
