What is 9y=2x for y I need help with this problem

mojhsa [17]

The first step for finding y is to divide both sides of the equation by 9.
9y ÷ 9 = 2x ÷ 9
When dividing 9 by 9 you must remember that any expression divided by itself equals 1.
y = 2x ÷ 9
Now write 2 ÷ 9 as a fraction.
y = $\frac{2}{9}$ x
This means that the answer to your question is that y = $\frac{2}{9}$ x.
Let me know if you have any further questions.

Henrietta is planting a new flower garden she must have yellow and red rose bushes let X represent the number of yellow rose bus

salantis [7]

Answer:

$x \geq 4y$

$7.50x+4.75y\leq 125$

$x > 0$

$y > 0$

Step-by-step explanation:

Let

x -----> the number of yellow rose bushes

y -----> the number of red rose bushes

we know that

At least means "greater than or equal to"

$x \geq 4y$ ----> inequality A

$7.50x+4.75y\leq 125$ -----> inequality B

additionally

The number of roses cannot be a negative number

$x > 0$ ----> inequality C

$y > 0$ ----> inequality D

therefore

The restraints are

$x \geq 4y$

$7.50x+4.75y\leq 125$

$x > 0$

$y > 0$

Please answer and explain (algebra II problem): <br> -3/2x - 1/2y = 8<br> What is the slope?

elixir [45]

Answer:

<em>slope= -3</em>

Step-by-step explanation:

firstly calculating the values of x and y for slopes.

-3/2x - 1/2y = 8

(-3x-y)= 8×2

-(3x+y) = 16

3x+y = -16

if x= -2

-6 + y = -16

y=-10

.: (x₁,y₁)=(-2,-10)

if x= -5

-15 + y = -16

y = -1

.: (x₂,y₂)=(-5,-1)

Using slope formula,

slope= (y₂-y₁)/(x₂-x₁)

slope = [-1-(-10)] / [-5-(-2)]

slope= [-1+10]/[-5+2]

slope= 9/(-3)

slope= -3
