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.
