Answer: The slope is 25. Y intercept is 100

Step-by-step explanation: Using y2-y1/x2-x1 just enter in any two x and y coordinates you want. For example...

1. (10, 350) and (20, 600)

2. 600-350/20-10

3. 250/10

4. Simplifies to 25.

1. Plug the points into y=mx+b

2. 350=25(10)+b

3. 350-250=250-250+b

4. 100=b

Adding 2/8 and -4/8 gives us 2/8

Can someone do this, and explain it please!

Answers

I think it’s C because
It’s A. the 10 is saying every week so that is what will be multiples of something. 10n(weeks). But you need to ADD the 25 that was mentioned. Key words like “every” means that will have the variable added on with the number. so every week is 10$. the 10$ is what needs to have the “n”. hope that makes sense !

How do I convert a polynomial into standard form?

Answers

Answer:

One way to write a polynomial is in standard form. In order to write any polynomial in standard form, you look at the degree of each term. You then write each term in order of degree, from highest to lowest, left to right.

Step-by-step explanation:

Answer:

1) Write the term with the highest exponent first

2) Write the terms with lower exponents in descending order

3) Remember that a variable with no exponent has an understood exponent of 1

4) A constant term (a number with no variable) always goes last.

 Step-By-Step Explanation:

Here is an example:

1) 6y3+4y5-2y2-6y+8y4+7

The highest exponent is the 5, so that entire term must be written first:4y5

The next highest exponent is the 4 so that term comes next. So far we have 4y5+8y4

The next highest exponent is the 3 so add that term to get

4y5 +8y4+6y3

Then comes 2. Notice that this term is negative, so don't forget to include the negative sign:

4y5 +8y4 +6y3-2y2

Remember that term has an understood exponent of 1 so it comes next. 4y5+8y4+6y3-2y2 -6y

The constant term (a number with no variable) always comes last so the final answer is:

4y5+8y4+6y3-2y2-6y+7

Hope this Helps! Tell me if I'm wrong

how to find a common denominator in fractions

Answers

Find the greatest common factor

Answer:

Step-by-step explanation:

A way you can find common denominators are like say you have a fraction, 2/3 and want to find a fraction equivalent to that, or common factors, you can multiply both the numerator and denominator by the same number. So if I have 2/3 and want a denominator or 9, I can do 2/3 times 3/3 and get 6/9 which is the same as 2/3. If you need anymore help or this is not the answer you wanted, just tell meh

Two water tanks are being filled. The water in Tank A is 3 inches deep, and the depth of the water increases 4
inches every hour. The water in Tank B is 10 inches deep, and the depth is increasing by 2 inches every hour.
Write an inequality to determine when the water in Tank A will be deeper than the water in Tank B.

Define the variable:

Write the inequality:

Answers

Answer:

variable: number of hours

inequality (unsimplified): 4x+3 > 2x+10

inequality (simplified): x > 3.5

at least 4 hours

Step-by-step explanation:

we can use mx+b to solve this. m will be the rate at which the water level rises and b will be your stating point. x defines the hour; this is your varible as it can change

Tank A: 4x+3

Tank B: 2x+10

since we want to find when tank a will have be deeper than tank b, we set the inequality to solve for greater than tank a: 4x+3 > 2x+10

subtract 3 to both sides: 4x > 2x + 7

subtract 2x to both sides: 2x > 7

divide both sides by 2: x > 3.5
