(x+1) x (3x-4) is the answer
vichka [17]2 years ago

Answer:

( x + 1 ) ( 3 x − 4 )

Step-by-step explanation:

3x^2− x − 4

Factor − 1 out of − x .

3 x^2 − ( x ) − 4

Rewrite − 1 as 3 plus − 4

3 x^2 + ( 3 − 4 ) x − 4

Apply the distributive property.

3 x^2 + 3 x − 4 x − 4

Group the first two terms and the last two terms.

( 3 x 2 + 3 x ) − 4 x − 4

Factor out the greatest common factor (GCF) from each group.

3 x ( x + 1 ) − 4 ( x + 1 )

Factor the polynomial by factoring out the greatest common factor, x + 1 .

( x + 1 ) ( 3 x − 4 )

Determine if the equation y = 2/5 x − 4 y=25x-4 represents a proportional relationship. If so, determine the constant of proport
Vilka [71]

Answer:

The linear equation represents a proportional relationship and its constant of proportionality is k = \frac{2}{5}.

Step-by-step explanation:

A proportional relationship exists when the following relationship is observed:

u = k\cdot v

Where:

u - Dependent variable.

v - Independent variable.

k - Proportionality constant.

If y =\frac{2}{5}\cdot x - 4 and v = x and u = y+4, the following expresion is found:

y = \frac{2}{5}\cdot x -4

y + 4 = \frac{2}{5}\cdot x

u = \frac{2}{5}\cdot v

The linear equation represents a proportional relationship and its constant of proportionality is k = \frac{2}{5}.
