How do you convert slope intercept form into standerd form

1 answer:

5 0

This is the slope intercept form y=mx+b and this is the standard form ax+by=c, now I am going to show you how to do this with numbers so is much easier. Say we have 4x+2y=10 as a standard form we have to set y by itself first we have to subtract 4x from both sides (because in order to get rid of a positive you have to use a negative) now we have 2y=-4x+10, now our next step is to divide both sides by 2 to leave y by itself (because in order to get rid of a multiplication is with a division) this gives you y=-4/2x+10/2. now our final step is to simplify what we can in this case 4 can be divide by 2 and get 2 and 10 can be divide by 2 and get 5 this means our simplified form is y=-2x+5

Hope this helps

Step-by-step explanation:

The area (A) of a trapezoid is calculated as

A = 0.5h(a + b)

where h is the perpendicular height and a, b the parallel sides.

Given A = 120, then

0.5 × 8(a + b) = 120, that is

4(a + b) = 120 ( divide both sides by 4 )

a + b = 30 cm → D

Answer:

1.One proportion

2. Proportions from Dependent Samples

3. Two Independent Proportions

4. One Mean

5. Means from Dependent Samples

6. Two Independent Means

Step-by-step explanation:

What proportion of Americans believe in climate change? - One proportion

From the above information, there is only one sample and the question is about proportion. So, we must use "One proportion".

Do college students change their view on climate change as they go through college? One hundred freshman are asked if they believe in climate change. The same students are asked four years later if they also believe in climate change. - Proportions from Dependent Samples

From the information given, there are two samples and samples are dependent ( that is same students are asked four years later). Furthermore, the question is about proportion, we must use " Proportions from dependent samples ".

Is there a difference in the proportion of men and women who believe in climate change? - Two Independent Proportions

From the information given, there are two independent samples and they are asking about proportion, we must use "Two independent proportions".

What is the average amount of time that Americans spend watching or reading the news a day? - One Mean

From the information, there is only one sample and they are asking about mean. Therefore, we must use ". One mean".

Is there a difference in the amount of time that college students spend reading or watching the news as they go through college? One hundred students were asked as freshmen and as senior how many minutes a day they spent reading or watching the news? - Means from Dependent Samples

There are two samples and samples are dependent ( the same students are asked four years later). Also, they are asking about mean, we must use "Means from dependent samples ".

Is there is a difference in the amount of time that Republicans and Democrats spend watching or reading the news? - Two Independent Means

From the information given, there are two independent samples and they are asking about mean, we must use "Two independent means".

In the barn, there are horses and chickens. There are 11 heads and 32 legs altogether. How many chickens are there?

Masteriza [31]

Answer:

6 Chickens

Step-by-step explanation:

Let H represent the number of horses and C represent the number of chickens. Since there are 32 legs altogether this means that on equation to use would be given by:

2C + 4 H = 32 (Eq. 1)

Another equation can be made from the fact that there are 11 heads or 11 animals altogether which can be written as:

C + H = 11 (Eq. 2)

From Eq. 2, solve for the number of chickens:

C + H = 11

C = 11 - H (Eq. 3)

Substituting Eq. 3 in Eq. 1, the number of horses can be determined:

2 C + 4 H = 32

2 ( 11 − H ) + 4 H = 32

22 − 2 H + 4 H = 32

2H = 32 − 22

2 H = 10

H = 5 Eq.4

Putting Eq.4 in Eq.1

2C + 4*5 = 32

2C = 32 - 20

2C = 12

C = 12/2

C = 6
