Answer:

3/4; 1/4, 1/4, 1/4

Step-by-step explanation:

The intent here is to let you demonstrate your understanding that multiplication by an integer is the same as repeated addition.

Your knowledge of fractions tells you ...

$\dfrac{1}{4}\times3=\dfrac{3}{4}$

The factor of 3 means this is equivalent to adding 1/4 a total of 3 times:

$\dfrac{1}{4}\times3=\dfrac{1}{4}+\dfrac{1}{4}+\dfrac{1}{4}$

What is the equation standard form of through (2,-4))and the slope is -4

Sloan [31]

Answer:

4x + y = 4

Step-by-step explanation:

Equation of Line in point slope form is given as:

$y - y_1= m(x-x_1)$

Plug $x_1= 2\: and\: y_1= - 4$ in the above equation we find:

$y - ( - 4) = - 4(x - 2) \\ \\ y + 4 = - 4x + 8 \\ \\ 4x + y + 4 - 8 = 0 \\ \\ 4x + y - 4 = 0 \\ \\ 4x + y = 4 \\this \: is \: the \: required \: equation.$

You have seen that the total number of lights in a triangular lighting rig is given by T(n) = n2/2 + n/2, while T(n+1) = n2/2 +

inn [45]

Based on the scenario, the reduced form of f(n) is :

f(n) = n^4/4+n^3 + 5n^2/4+n/2

or, it could also be written as

n/4 (n+1) (n^2 + 3n + 2)
