Th term of a seq uence is n(n-4) /n+3 Work out the sum of the 1st and 6th terms.
AlekseyPX

Answer:

7/12

Step-by-step explanation:

The nth term Tₙ = n(n-4) /n+3.

The 1st term T₁ = 1(1 - 4)/(1 + 3) = -3/4

The 6th term T₆ = 6(6 - 4)/(6 + 3) = 6(2)/9 = 2(2)/3 = 4/3

So,  the sum of the 1st and 6th terms is T₁ + T₆ = -3/4 + 4/3

= (-9 + 16)/12

= 7/12

Simplify 5/8x -2y +3/4x-8y
AleksandrR [38]

Answer:

On simplification,  \frac{5}{8}x - 2y + \frac{3}{4}x -8y   =   (\frac{11}{8}) x - 10y

Step-by-step explanation:

Here, the given expression is:

\frac{5}{8}x - 2y + \frac{3}{4}x -8y

Now, we can perform operations only on LIKE TERMS,

So, in this expression, separate the like terms we get:

\frac{5}{8}x - 2y + \frac{3}{4}x -8y  =  \frac{5}{8}x +  \frac{3}{4}x - 2y -8y\\= (\frac{5}{8} +  \frac{3}{4})x -(2y + 8y)  = (\frac{5 + 3(2)}{8}) x - (10y)\\= (\frac{11}{8}) x - 10y\\\implies  \frac{5}{8}x - 2y + \frac{3}{4}x -8y   =   (\frac{11}{8}) x - 10y

Hence, on simplification,  \frac{5}{8}x - 2y + \frac{3}{4}x -8y   =   (\frac{11}{8}) x - 10y
