Question

Identify the variables, constants, and coefficients in the simplified expression.

5xy - 3yz - 5xz + yz - 4xz + 7xy
First combine all like terms:
(5xy+7xy)+(yz-3yz)-(5xz+4xz)
12xy-2yz-9xz


Now replace the x,y & z terms with their numeric values:
and evaluate it for x = 10, y = -4, z = -6.
12(10*-4)-2(-4*-6)-9(10*-6)
12*-40-2*24-9*-60
-480-48+540=12 ans.

Answer 1

You got it right. Good for you!!

Answer 2

i just dont know how to identify

Answer 3

the variables are x y and z
The coefficients are 12, -2, and -9
There are no constants

Answer 4

6z + 1 + 4x^2 - 3y3 + 7x - 8y2 + 2x2 - x + 5z - 17
first you need to combine all like terms:
(6z+5z)+(4x^2+2x^2)-3y3-8y^2+(7x-x)+(1-17)
11z+6x^2-3y^3-8y^2+6x-16


now replace x with -2, y with -3, z with -5.
11*-5+6*(-2)^2-3*(-3)^3-8*(-3)^2+6*(-2)-16
-55+6*4-3*-27-8*9-12-16
-55+24+81-72-12-16
-50 ans.

Answer 5

is this right? and how do you even Identify the variables, constants, and coefficients in the simplified expression.

Answer 6

What is the simplified expression?

Answer 7

the first

Answer 8

The simplified expression is the one you get after you combine the like terms.

Answer 9

i got that
but in the one i just posted^^ whats the coff and constant?/

Answer 10

In your case it is 11z+6x^2-3y^3+6x-16

Answer 11

The coefficients are 11, 6, -3, 6 and =16
The variables are x, y, and z
The constants are -16

Answer 12

I made a typo in the coefficients. they are 11, 6, and -3

Answer 13

okay

thank you mertsj
