Rewrite x+2y=-4 in slope intercept

Mathematics
2 answers:
Ivan3 years ago
6 0

Answer:

How do you write

x+2y=4

into slope intercept form?

Answer is:

y=−12x+2

Step-by-step explanation:

Slope intercept form can be represented as

y=mx+b

To get an equation into this form, we should try to get y all alone.

So then from x+2y=4

first, we can subtract x from both sidesand get 2y=−x+4

then, we can divide both sides by 2 to get it in slope intercept form

y=−12x+2

I think is like this. Hope it helps>3

The expression 100 + 20m100+20m100, plus, 20, m gives the volume of water in Eduardo's pool (in liters) after Eduardo spends mmm
hodyreva [135]

Answer:

205 litres

Step-by-step explanation:

Given:

Volume of water is given as:

V=100+20m (in litres)

<em>m</em> is the time in minutes spent filling water in Eduardo's pool.

To find:

Volume of water in the pool after the water is filled for 5\frac{1}{4} minutes.

Solution:

Here, volume of water in the Pool (in litres) is given by the equation:

V=100+20m ....... (1)

Where m is the time for which Eduardo fills the pool.

Here, we are also given that

m = 5\frac{1}{4} minutes = \frac{5\times4+1 }{4}=\frac{20+1}{4}=\frac{21}{4} minutes

And we have to find the value of V after \frac{21}{4} minutes.

Let us put the value of m as \frac{21}{4} minutes in the equation (1) to find the value of V.

V=100+20m\\\Rightarrow V = 100 + 20 \times \frac{21}{4}\\\Rightarrow V = 100+105\\\Rightarrow \bold{V = 205\ litres}

So, the volume of water in the pool after \frac{21}{4} minutes is <em>205 litres.</em>

PLEASE!!! HELP!!! Question: If you have points on a graph that plot (1,7), (2,8), (3,5) and (4,6) what would be the slope?
kakasveta [241]

Answer:

1

Step-by-step explanation:

You only need two points to find the slope.

Let's use (1,7) and (2,8).

The formula for slope is (y2-y1)/(x2-x1)

Let's plug the values in:

(8-7)/(2-1) = 1.

So, the slope is 1.

Simplify. Write answers with positive exponents only.
allochka39001 [22]

Answer:

The answer to your question is 2⁸x²⁰ y²⁴    or    256x²⁰y²⁴

Step-by-step explanation:

Data

                    (2x³y³)⁴ (2x²y³)⁴

To solve this problem, use the law of exponents.

1.- Use the law of Power of a power rule

                    (2x³y³)⁴ (2x²y³)⁴ =           (2⁴x¹²y¹²) (2⁴x⁸y¹²)      

2.- Use the multiplication rule

                      (2⁴x¹²y¹²) (2⁴x⁸y¹²)  =    2⁸x²⁰ y²⁴

3.- The answer is      2⁸x²⁰y²⁴ or we can simplify more like

                                 256x²⁰y²⁴
