Find a common factor for 3y^3+2y^2 and 6y^4+4y^3

Anit [1.1K]

Answer:

$3y + 2$

Step-by-step explanation:

We want to find a common factor for

$3 {y}^{3} + 2 {y}^{2}$

and

$6 {y}^{4} + 4 {y}^{3}$

We factor each of them to get;

$3 {y}^{3} + 2 {y}^{2} = {y}^{2} (3y + 2)$

and

$6 {y}^{4} + 4 {y}^{3} = 2 {y}^{3} (3y + 2)$

We can observe now that;

The factor common to both expression is

$3y + 2$

What is a correct equation for the line passing through the point (-2,1) and having slope m=1/2

frez [133]

Step-by-step explanation:

The point-slope form of an equation of a line:

$y-y_1=m(x-x_1)$

m - slope

We ahve the slope m = 1/2 and the point (-2, 1). Substitute:

$y-1=\dfrac{1}{2}(x-(-2))$

$y-1=\dfrac{1}{2}(x+2)$ - point-slope form

Covert to the slope-intercept form (y = mx + b):

$y-1=\dfrac{1}{2}(x+2)$ use the distributive property

$y-1=\dfrac{1}{2}x+1$ add 1 to both sides

$y=\dfrac{1}{2}x+2$ - slope-intercept form

Convert to the standard form (Ax + By = C):

$y=\dfrac{1}{2}x+2$ multiply both sides by 2

$2y=x+4$ subtract x from both sides

$-x+2y=4$ change the signs

$x-2y=-4$ - standard form

Convert to the general form (Ax+By+C=0):

$x-2y=-4$ add 4 to both sides

$x-2y+4=0$ - general form
