Let there exists a point (x, y) on the given line.

Slope of all points must be same, as they lie on the same line.

=> (y - 1)/(x - 2) = (4 - 1)/(-4 - 2)

=> (y - 1)/(x - 2) = - 1/2

=> y - 1 = (-½) (x - 2)

Option 1 is the correct option

The distance between Detroit, Ml to Paris, France is approximately 3930 mi. Flying from Detroit to Paris take 8 hr with the jet

slamgirl [31]

Answer:

a) $s=482moh$

b) $s'=9mph$

Step-by-step explanation:

From the question we are told that:

Distance $d=3930mi$

Time of flight $T=8hr$

Flight back $T_b=8.3hr$

Generally the equation for Time for flight with jet steam is mathematically given by

$T=\frac{d}{s+s_1}$

$8=\frac{3930}{s+s'}$

$s+s'=491.3 ....equ1$

Generally the equation for Time for flight against jet steam is mathematically given by

$T=\frac{d}{s-s_1}$

$8.3=\frac{3930}{s-s_1}$

$s+s'=473.5......equ 2$

Solving equ 1 and equ 2 simultaneously

$s+s'=491.3$

$s+s'=473.5$

Therefore

$s=482moh$

$s'=9mph$

If you factor the denominator of the left multiplicand...

[(a-4)(a+3)]/[a(a-4)] you can see that the (a-4)s cancel out leaving:

(a+3)/a

now you have

(a+3)/a * 2a^3/((a+3)(a-1)) so the (a+3)s cancel out leaving:

1/a * 2a^3/(a-1) which is:

2a^3/(a(a-1)) so now a^1 cancel leaving

2a^2/(a-1)
