Hello!
The answer is:
The value of the given expression evaluated with x equals to -2 and y equals to 4, is equal to 56 units.
Why?
To solve the problem, we need to evaluate both variables for the given values:
[tex]x=-2[/tex]
and
[tex]y=4[/tex]
So, we are given the expression:
[tex]-6x^{3}-y^{2}-3xy[/tex]
Then, evaluating the given values for both variables, we have:
[tex]-6*(-2)^{3}-(4)^{2}-3*(-2)*(4)=(-6*-8)-(16)+24=48-16+24=56[/tex]
Hence, we have that the answer is:
The value of the given expression evaluated with x equals to -2 and y equals to 4, is equal to 56 units.
Have a nice day!
Answer:
The value of given expression = 56
Step-by-step explanation:
It is given an expression in variable x and y
-6x³ - y² - 3xy
To find the value of given expression
Let expression be,
-6x³ - y² - 3xy
When x = -2 and y =4
-6x³ - y² - 3xy = -6(-2)³ - 4² - (3 * -2 * 4)
= -6*-8 - 16 + 24
= 48 - 16 + 24
= 56
Therefore the value of given expression is 56
