The midpoint of the line segment at (1,7) and (5,5) is A) (3,6) B) (2,6) C) (3,1) D) (2,1)

hammer [34]

Answer:

A) (3,6)

Step-by-step explanation:

Let M be the midpoint of the line segment at (1,7) and (5,5). Then:

$\mathsf{M\left(\dfrac{1+5}{2},\dfrac{7+5}{2}\right)}=\\=\mathsf{M\left(\dfrac{6}{2},\dfrac{12}{2}\right)}=\\=\mathsf{M\left(3,\,6\right)}$

Which is faster rate? 3 Laps in 5 minutes or 4 laps in 7 minutes?

ad-work [718]

To solve this, we first have to find an individual rate:
3/5
4/7
For the first one:
1 lap in 5/3 minutes
Second one:
1 lap in 7/4 minutes
find a common LCD
5/3 and 7/4
20/12 and 21/12
4 laps in 7 minutes is faster

Find a_1 and d for an arithmetic sequence with these terms. a_4=9and a_7=18

jonny [76]

$\bf \begin{array}{llll}
term&value\\
-----&-----\\
a_4&9\\
a_5&9+d\\
a_6&(9+d)+d\\
&9+2d\\
a_7&(9+2d)+d\\
&9+3d=\underline{18}
\end{array}\\\\
-------------------------------\\\\
9+3d=18\implies 3d=9\implies d=\cfrac{9}{3}\implies \boxed{d=3}$

$\bf n^{th}\textit{ term of an arithmetic sequence}\\\\
a_n=a_1+(n-1)d\qquad 
\begin{cases}
n=n^{th}\ term\\
a_1=\textit{first term's value}\\
d=\textit{common difference}\\
----------\\
n=7\\
d=3
\end{cases}
\\\\\\
a_7=a_1+(7-1)d\implies 18=a_1+(7-1)3\implies 18=a_1+18
\\\\\\
18-18=a_1\implies \boxed{0=a_1}$

Any suggestions or answers

KATRIN_1 [288]

The answer is D or a translation of 6 units to the right. This is because pre-image is shifted 6 units on the x axis to the right.
