Determine which function(s) is not a linear function. select all that apply. y=x^3/3 y= x/3 x=3 y= √x-3 y= | x+3 | y=3x

y=x^3/3 ; x=3 ; y= √x-3 ; and y= | x+3 | .

Step-by-step explanation:

In a linear function, we have both a y, an x, and the highest power of each is 1.

In the first function, x has a power of 3; this means it is nonlinear.

In the second function, both y and x have a power of 1; this means it is linear.

In the third function, there is no y; it is an x = c equation, which makes it a vertical line and thus not a function.  This means it is not a linear function.

In the fourth function, we have a square root; this means the power of x is 1/2, not 1, and the function is not linear.

In the fifth function, we have absolute value bars.  This means it is an absolute value function and not a linear function.

In the sixth function, both x and y have a power of 1; this means it is linear.

none of the option is correct.

step-by-step explanation:

it says to find which expression equals 9^3 sqrt 10 = ?

9^3 sqrt 10 = 729 sqrt 10.

checking option a. 5 sqrt 10 + 4 sqrt 10

5 sqrt 10 + 4 sqrt 10

= 9 sqrt 10.

checking option b. 5^3 sqrt 10 + 4^3 sqrt 10

5^3 sqrt 10 + 4^3 sqrt 10

= 125 sqrt 10 + 64 sqrt 10

= 189 sqrt 10.

checking option c. 5 sqrt 10 + 4^3 sqrt 10

5 sqrt 10 + 4^3 sqrt 10

= 5 sqrt 10 + 64 sqrt 10

= 69 sqrt 10.

checking option d. 5^3 sqrt 10 + 4 sqrt 10

5^3 sqrt 10 + 4 sqrt 10

= 125 sqrt 10 + 4 sqrt 10

= 129 sqrt 10.

hence, none of the option is correct.

answer: 180

step-by-step explanation:

12-2=10

20-2=18

18x10=180
