Answer:

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

Answer:

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

I WILL GIVE A BRANLIEST!<br>What is the graph of the functions?<br> y=2*2^x<br> y=-2*5^x

tekilochka [14]

For this case what you should know is that both functions are of the potential type.
We have then that
y = 2 * 2 ^ x
This function grows exponentially upwards.
y = -2 * 5 ^ x
This function grows exponentially downwards.

There are 59 eggs in the basket

Step-by-step explanation:

There are between 50 & 60 eggs in a basket

When Roza counts by 3's there are 2 leftover
When she counts by 5's there are 4 leftover

We need to find how many eggs in the basket

∵ When Roza counts by 3's there are 2 leftover

∵ When she counts by 5's there are 4 leftover

- That means the number of eggs when divided by 3 give

remainder 2 and when divided by 5 give remainder 4

- To find the number look for the numbers that divisible by 5 and

add 4 to them and then check the remainder when they divided

by 3

∵ Between 50 and 60 there is only one number divisible by 5

is 55 (not including 50 or 60)

∵ 55 + 4 = 59

∴ 59 gives remainder 4 when divided by 5

Let us check them with 3

∵ 59 - 2 = 57

∵ 57 is divisible by 3 ⇒ (57 ÷ 3 = 19)

∴ 59 when divide by 3 gives remainder 2

∴ 59 gives remainder 4 when divided by 5 and remainder 2 when

divided by 3

∴ The number of eggs in the basket is 59

There are 59 eggs in the basket

What is the solution to the following system of equations? x − 4y = 6 2x + 2y = 12 (0, 10) (10, 0) (6, 0) (0, 6)

frozen [14]

Answer:

(6,0)

Step-by-step explanation:

The given system has equations:

$x-4y=6$

$2x+2y=12$

Multiply the top equation by 2 to get:

$2x-8y=12$

$2x+2y=12$

Subtract the top equation form the bottom equation to get:

$2x-2x+2y--8y=12-12$

$\implies 10y=0$

$\implies y=0$

Put y=0 into $x-4y=6$

$x-4*0=6$

$\implies x=6$

Therefore the solution is (6,0)
