Y=(5x-4)/2 first move -2y to the other side to obtain a positive value and make y the subject

To get the equation 5x - 2y = 4 to the slope-intercept form, we will need to solve for y.

5x - 2y = 4

Let's get rid of the 5x on the left-hand side so we will be left with -2y on the left-hand side.

So, how could we go about that? Well, we could subtract 5x from the left-hand side. But for everything we do on one side, we do to the other side.

(5x - 2y) - 5x = 4 - 5x
-2y = 4 - 5x

Now let's get rid of the coefficient of -2 on the y variable.

Divide both sides by -2

-2y / -2 = (4 - 5x) / (-2)

y = 2 - 2.5x

We have it in the slope-intercept form, but let's algebraically manipulate the right-hand side so we have the -2.5x as the first term on the right-hand side.

So, y = -2.5x + 2 would be the answer to your question.

Rearrange the standard form of the equation below into y = mx + b by isolating y. <br> 5x − 2y = 6
Minchanka [31]

Answer:

y = \frac{5}{2} x - 3

Step-by-step explanation:

5x - 2y = 6 ( subtract 5x from both sides )

- 2y = - 5x + 6 ( divide through by - 2 )

y = \frac{5}{2} x - 3 ← in slope- intercept form

A population of rabbits in a lab, p(x), can be modeled by the function p(x) = 20(1.014)x , where x represents the number of days
Nitella [24]

Answer:

20 = initial population of the rabbits

1.014 = growth rate of the rabbits

the average rate of change from day 50 to day 100 is 0.8

Step-by-step explanation:

A population of rabbits in a lab, p(x), can be modeled by the function

p(x) = 20(1.014)^x

This model is exponential. Where 20 = initial population of the rabbits

1.014 = growth rate of the rabbits with 1.4% increase rate of the rabbits

To find the average rate of change from day 50 to day 100,

find the population p(50) and p(100). Subtract them and divide by 100 - 50 = 50. 

p(50) = 20(1.014)50 = 40.08... 

p(100) = 20(1.014)100 = 80.32... 

(80.32 - 40.08) / (100 - 50) = 40.24/50 = 0.8048. which is approximately 0.8 to the nearest tenth. 

The rate of change is 0.8.

Please help and explain with these 2 math questions!!!!!!
Volgvan

1)  -10x+y=4

Now, you should substitute x in every situation.

* x=-2 <em>=> -10*(-2)+y=4... 20+y=4... <u>y=-16</u></em>

<em />* x=-1 =>-10*(-1)+y=4... 10+y=4... <u>y=-6</u>

<u />*x=0 => -10*0+y=4... <u>y=4</u>

<u />* x=1 =>  -10*1+y=4... -10+y=4... <u>y=14</u>

<u />* x=2 => -10*2+y=4... -20+y=4... <u>y=24</u>

<u>2)</u> -5x-1=y

For example: x=0

-5*0-1=-1

<u>
</u>
