Answer:

\dfrac{149}{40}

\dfrac{38}{15}

Step-by-step explanation:

(\dfrac{7}{8} + \dfrac{4}{5}) - (\dfrac{9}{20} + \dfrac{-5}{2}) =

= (\dfrac{7}{8} \times \dfrac{5}{5} + \dfrac{4}{5} \times \dfrac{8}{8}) - (\dfrac{9}{20} + \dfrac{-5}{2} \times \dfrac{10}{10})

= (\dfrac{35}{40} + \dfrac{32}{40}) - (\dfrac{9}{20} + \dfrac{-50}{20})

= \dfrac{67}{40} - (-\dfrac{41}{20})

= \dfrac{67}{40} + \dfrac{41}{20} \times \dfrac{2}{2}

= \dfrac{67}{40} + \dfrac{82}{40}

= \dfrac{149}{40}

(-\dfrac{6}{4} + \dfrac{3}{2}) + (\dfrac{6}{5} + \dfrac{4}{3}) =

= (-\dfrac{3}{2} + \dfrac{3}{2})+ (\dfrac{6}{5} \times \dfrac{3}{3} + \dfrac{4}{3} \times \dfrac{5}{5})

= 0 + \dfrac{18}{15} + \dfrac{20}{15}

= \dfrac{38}{15}

Answer:

The sequence is a function

Step-by-step explanation:

Given

Sequence: A_0=100; A_n=A_{n-1}+75

Required

Is the sequence a function

To determine if the sequence is a function or not, we start by calculating its range from the domain:

When n = 0; A_0=100

When n = 1: A_1 = A_{1-1} + 75 = A_0 + 75 = 100 + 75 = 175

When n = 2; A_2 = A_{2-1} + 75 = A_1 + 75 = 175 + 75 = 250

When n = 3; A_3 = A_{3-1} + 75 = A_2 + 75 = 250 + 75 = 325

This implies that:

The domain (n) and the range (An) can be represented as:

\left[\begin{array}{c}n&-&0&1&2&3\\-&-&-&\end{array}\right]                       \left[\begin{array}{c}A_n&-&100&175&250&325\\-&-&-&\end{array}\right]

<em>The above shows that the sequence is a one to one relation and a one to one relation is always a function.</em>

Four less than the quotient of a number and 4 is 14. What is the number? Let n be the unknown number.
Maru [420]
So the equation is n/4-4=14
then you +4 to both sides 
n/4-4=14 so now the equation is n/4=18 then you multiply 18 by 4 and get 72
   +4    +4
then to check your work
72/4-4=14
so N=72
Hope I helped :)

Which undefined geometric term is described as a location on a coordinate plane that is designated by an ordered pair, (x, y)?
jolli1 [7]

Answer: D.  Point

A point is a location. On the 2D coordinate plane, it's described by (x,y). Think of it like an address or like latitude/longitude. A point is an undefined term in geometry as it doesn't build off of smaller elements.
