What is the slope againnn ?

Mathematics

Answer:

slope = -1/2

Step-by-step explanation:

Find two points on the line that are easy to read. The easiest points to read are points that lie on grid intersections.

For example, use point (1, 9) and point (3, 8).

slope = rise/run

Rise is the vertical distance between points. Up is positive. Down is negative.

Run is the horizontal distance between points. Right is positive. Left is negative.

You need to go from one point to the other points and note the rise and run.

Start at (1, 9).

Go <em>1 unit down</em>. That is a rise of <em>-1</em> since you went <em>down 1 unit</em>.

Now go <em>2 units right</em>. That is a run of <em>+2</em> since you went <em>2 units to the right</em>.

slope = rise/run = -1/2

Answer: slope = -1/2

Answer:

-1/2

Step-by-step explanation:

To find the slope, pick two points on the line, and use the slope formula

( 1,9) and  (5,7)

m = (7-9 )/(5-1)

   -2/4

  -1/2

Can you please solve and explain how
Karolina [17]

First, it would help to simplify each side more:

Left side: 36 + 3(4x - 9) = 36 + 12x - 27 = 12x + 9

Right side: c(2x + 1) + 25 = 2cx + c + 25

Write the simplified equation:

12x + 9 = 2cx + c + 25

Usually when there is no solution, the coefficients of the variable on both sides are the same, so we can make the coefficient if x on the right side into 12:

2cx >>> 12x

Then, c must equal 6 to make this true.

The answer is choice (C).

Classify the sequence arithmetic , geometric, or neither
Feliz [49]

Answer:

Geometric

Step-by-step explanation:

Given terms are {3, -1, 1/3, -1/9............}

If we have common difference between the terms then it is arithmetic

If we have common ratio between the terms then it is Geometric

Difference of 3  and -1  is 4

Difference of 1/3  and -1 is -4/3

Common difference it not same so it is not Arithmetic

Now we check common ratio

we divide second term by first term

first term is 3  and second term is -1

\frac{-1}{3}

now we check with next two terms

\frac{\frac{1}{3}}{-1}=\frac{-1}{3}

common ratio is -1/3

So this is Geometric

A fluid moves through a tube of length 1 meter and radius r=0.006±0.00025 meters under a pressure p=4⋅105±2000 pascals, at a rat
iris [78.8K]

Answer:

Maximum error for viscosity is 17.14%

Step-by-step explanation:

We know that everything is changing with respect to the time, "r" is changing with respect to the time, and also "p" just "v" will not change with the time according to the information given, so we can find the implicit derivative with respect to the time, and since

n = (\frac{\pi}{8}) (\frac{pr^4}{v})\\

The implicit derivative with respect to the time would be

\frac{dn}{dt}  = \frac{\pi}{8} ( \frac{r^4}{v} \frac{dp}{dt}  + \frac{4pr^3}{v}\frac{dr}{dt} )

If we multiply everything by    dt   we get  

dn  = \frac{\pi}{8} ( \frac{r^4}{v} dp  + \frac{4pr^3}{v}  dr})

Remember that  the error is given by   \frac{dn}{n}   therefore doing some algebra we get that

\frac{dn}{n}  =    4 \frac{dr}{r}  +  \frac{dp}{p}

Since,    r = 0.006   ,   dr = 0.00025 ,  p = 4*105   ,   dp = 2000  we get that

\frac{dn}{n} = 0.1714

Which means that  the maximum error for viscosity is 17.14%.

mr. smith has a maximum of $50 to spend at a museum. a ticket to the museum costs $7. he can spend p dollars to buy other things
7nadin3 [17]

The inequality that can be used to find the values for p is p + 7 ≤ 50.

Given the information,

Mr. Smith can only spend up to $50 at a museum. The museum admission ticket is $7. He can use his P dollars to purchase other items from the museum.

The total budget is $50.

The cost per ticket is $7

⇒ Total spent ≤  Total Budget

⇒ p + 7 ≤ 50

⇒ p ≤ 43

Therefore, p + 7 ≤ 50 will be the inequality that aids in determining the range of values for p.
