Answer:

option 4

Step-by-step explanation:

$5x + 2y = 2\\2y = -5x + 2\\y = -\frac{5}{2}x + 1\\\\Slope = -\frac{5}{2}, \ y - intercept = 1$

$3x - 3y = 18\\3y = 3x - 18\\y = x - 6\\\\Slope = 1, \ y - intercept = -6$

A man took a trip, traveling by train. He looked out the window during the first 1/3 of the trip. He then slept for 1/5 of the r

kifflom [539]

Answer: 528 km

Step-by-step explanation:

Let x be the total distance traveled by train.

Then, the total time he spent on looking outside the window and in sleeping = $\frac{x}{3}+\frac{x}{5}=\frac{8x}{15}$

Then the remaining distance = $x-\frac{8x}{15}=\frac{7x}{15}$

The time he spent on reading = $\frac{1}{2}\times(\frac{7x}{15})=\frac{7x}{30}$

Since, the train traveled 17.6 km more while he read than while he slept.

Then,

$\frac{7x}{30}-\frac{x}{5}=17.6\\\Rightarrow\ \frac{7x-6x}{30}=17.6\\\Rightarrow\ \frac{x}{30}=17.6\\\Rightarrow\ x=30\times17.6\\\Rightarrow\ x=528$

Hence, the train traveled 528 km.

Factorise : 64a cube minus 27b cube minus 144a square b plus 108ab square .

Svetlanka [38]

Answer:

$16a(4a^2-9a)+27b^2(4a-b)$

Step-by-step explanation:

The question is not properly formatted, here is a good format for proper understanding and readability

$64a^3-27b^3-144a^2+108ab^2$

let us first collect/ group like terms

$64a^3-144a^2+108ab^2-27b^3$

we can now bring out the common factors we have

$16a(4a^2-9a)+27b^2(4a-b)$

<em>The simplified expression is </em>

$16a(4a^2-9a)+27b^2(4a-b)$
