Write an equation that represents the situation

Nadya [2.5K]

Answer:

y = x - 3

Step-by-step explanation:

Given line passes through the points $(3,\:0)=(x_1,\:y_1) \:\&\:(6,\:3)=(x_2,\:y_2)$

Equation of line in two point form is given as:

$\frac{y - y_1}{y_1 - y_2} = \frac{x - x_1}{x_1 - x_2} \\ \\ \therefore \: \frac{y - 0}{0 - 3} = \frac{x - 3}{3 - 6} \\ \\ \therefore \: \frac{y }{- 3} = \frac{x - 3}{ - 3} \\ \huge \red{ \boxed{\therefore \: y = x - 3}} \\ \implies \: y = mx + b$

PilotLPTM [1.2K]

Answer:

105th term of given series is

$a_n=\dfrac{105}{2}$

Step-by-step explanation:

Given series is

$\dfrac{1}{2},\ 1,\ \dfrac{3}{2},\ 2,\ \dfrac{5}{2}.....$

As we can see,

$\textrm{First term},a_1=\dfrac{1}{2}$

Also,

$1-\dfrac{1}{2}=\dfrac{3}{2}-1=2-\dfrac{3}{3}=.....=\dfrac{1}{2}$

hence, we can say given series is in arithmetic progression,

with common difference,

$d=\ \dfrac{1}{2}$

As given in question the nth term in A.P is given by

$a_n=a_1+(n-1)d$

since we have to find the 105th term, so we can write

$a_{105}=\dfrac{1}{2}+(105-1)\dfrac{1}{2}$

$=\dfrac{1}{2}+\dfrac{104}{2}$

$=\dfrac{105}{2}$

Hence, the 105th term of given series of A.P is $\dfrac{105}{2}$ .
