Find the slope for the pair of points (1,1)(4,-4)

wolverine [178]

(1, 1) and (4, -4)

Slope formula is : m = (y₂-y₁) / (x₂-x₁)

In this case :

x₁ = 1 ; x₂ = 4 ; y₁ = 1 ; y₂ = -4

Now that you know what variable counts as what, we simply just need to plug everything in.

m = (-4 - 1) / (4 - 1)

Simplify.

m = -5/3

Therefore, your slope is -5/3

Dana can type nearly 90 words per minute. Use this information to find the number of hours it will take her to type 2.6 x 105 wo

Vlad1618 [11]

Dana can type 90 words per minute.

Since, 1 minute = $\frac{1}{60}$ hours

Therefore, number of words she can type = $\frac{90}{\frac{1}{60}}$

= 90×60

= 5400 words per hour

If she types $2.6\times 10^5$ words in 'x' hours.

Number of words Dana types with the given speed in 'x' hours = Speed of typing × Time

= $5400\times x$

Therefore, $5400\times x =2.6\times 10^5$

$5400x=260000$

$x=\frac{260000}{5400}$

$x=48.15$ hours

Therefore, Dana types $2.6\times 10^5$ words in 48.15 hours.

Find the value of x<br> in this polygon.<br> help !!!

Paladinen [302]

Answer:

solution,

Sum of exterior angle of polygon=360°

$3x - 5 + 2x + 10 + 90 = 360 \\ or \: 3x + 2x - 5 + 10 + 90 = 360 \\ or \: 5x + 5 + 90 = 360 \\ or \: 5x + 95 = 360 \\ or \: 5x = 360 - 95 \\ or \: 5x = 265 \\ or \: x = \frac{265}{5} \\ x = 53$

Hope this helps...

Good luck on your assignment...
