Find the solution set. y^2+4y=0 seperate the two values with a comma

y = - 4, y = 0

Step-by-step explanation:

Given

y² + 4y = 0 ← factor out y from each term on the left side

y(y + 4) = 0 ← in factored form

Equate each factor to zero and solve for y

y = 0

y + 4 = 0 ⇒ y = - 4

y=0,y=-4

Step-by-step explanation:

y^2+4y=0

In this kind of question,you will have to look for what is common to the two figures

Then solve,it was observed that y is common to the two,then you will have to factorise

y(y+4)=0

Which means that y outside the bracket equals to 0

That is y=0

Let's move to the bracket

y+4=0

Substrate 4 from both sides y=-4

We were able to get to values for y

y=0,y=-4

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
