Question No 3:

The function is Linear as highest power is 1.

Quadratic Term: None

Linear Term: x

Constant: -1

Question No 4:

The function is Quadratic as highest power is 2.

Quadratic Term: 2x^2

Linear Term: -3x

Constant: 5

Question No 5:

The function is Quadratic as highest power is 2.

Quadratic Term: 3x^2

Linear Term: 15x

Constant: None

Question No 6:

The function is Linear as highest power is 1.

Quadratic Term: None

Linear Term: 3x

Constant: -5

Question No 7:

The function is Quadratic as highest power is 2.

Quadratic Term: -2x^2

Linear Term: -8x

Constant: None

Step-by-step explanation:

Question No 3:

The term given is: y=x(1-x)-(1-x^2)

Simplifying:

$y=x-x^2-1+x^2\\y=x-1$

So, the function is Linear as highest power is 1.

Quadratic Term: None

Linear Term: x

Constant: -1

Question No 4:

The term given is: y=2x^2-(3x-5)

Simplifying:

$y=2x^2-(3x-5)\\y=2x^2-3x+5$

So, the function is Quadratic as highest power is 2.

Quadratic Term: 2x^2

Linear Term: -3x

Constant: 5

Question No 5:

The term given is: y=3x(x+5)

Simplifying:

$y=3x(x+5)\\y=3x^2+15x$

So, the function is Quadratic as highest power is 2.

Quadratic Term: 3x^2

Linear Term: 15x

Constant: None

Question No 6:

The term given is: y=3x-5

Simplifying:

It is in simplest form.

y=3x-5

So, the function is Linear as highest power is 1.

Quadratic Term: None

Linear Term: 3x

Constant: -5

Question No 7:

The term given is: f(x)=-x(2x+8)

Simplifying:

$f(x)=-x(2x+8)\\f(x)=-2x^2-8x$

So, the function is Quadratic as highest power is 2.

Quadratic Term: -2x^2

Linear Term: -8x

Constant: None

Answer from: Quest

d, x=8

step-by-step explanation:

simplifying

4x + -5 = 2x + 11

reorder the terms:

-5 + 4x = 2x + 11

reorder the terms:

-5 + 4x = 11 + 2x

solving

-5 + 4x = 11 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-5 + 4x + -2x = 11 + 2x + -2x

combine like terms: 4x + -2x = 2x

-5 + 2x = 11 + 2x + -2x

combine like terms: 2x + -2x = 0

-5 + 2x = 11 + 0

-5 + 2x = 11

add '5' to each side of the equation.

-5 + 5 + 2x = 11 + 5

combine like terms: -5 + 5 = 0

0 + 2x = 11 + 5

2x = 11 + 5

combine like terms: 11 + 5 = 16

2x = 16

divide each side by '2'.
