Evaluate 1/3-2x-4y2 for x = 3 and y = -1

-29

Step-by-step explanation:

substitute the y and x values whith there given values

so 1/3-2(3)-4(-1)2

first simplify (-1)2 or (-1)(-1) which is 1 so now the equation is 1/3-2(3)-4(1)

now you must solve all the values that have multiplying involved so you have 1/3-6-4

now subtract 6 and 4 to get 1/3-10

now find the LCD which is 3

multiply the LCD by both terms to get 1-30 which equals -29

For this case we have the following expression:

We must evaluate the expression when:

Substituting we have:

Equal signs are added and the same sign is placed.

Different signs are subtracted and the major sign is placed.

true? is that what you're asking or do you mean something else?

you would need to know all the numbers that are on there
