If KX - 8Y + 4 =0 is parallel to the line who’s equation is 3X -4Y+8 = 0. What is the value of K
Alex_Xolod [135]

So - first you gotta put it in the y = mx + b form.


4Y = 3X +8

=> y = 4/3X + 1/2

A parallel line has the same slope. So if 3X - 4Y + 8=0 has a slope of 4/3 then the value of K must also be 4/3

Dmitrij [34]

Answer:

The result of the integration is \frac{x^5}{5}

Step-by-step explanation:

Integration of a power of x:

The integration of a power of x is:

\int x^{n} dx = \frac{x^{n+1}}{n+1}

In this question:

n = 4. So

\int x^{4} dx = \frac{x^{4+1}}{4+1} = \frac{x^5}{5}

The result of the integration is \frac{x^5}{5}
