Stop 1 : -

15 + 5 = 20

20 - 2 = 18

So, on the first stop 18 passengers were left on the bus going to the next stop.

Stop 2 : -

18 + 3 = 21

21 - 15 = 6

So, 6 passengers get off at the 2nd stop.

Hope I helped ya!!

Given m∥n, find the value of x and y.

kupik [55]

X=2
y=149
————-
Solve 8x+15=7x+17
alternate angles are equal
x=2

Substitute 2 in 8x+15 =31
180-31=149
y=149
Angles on a straight line add up to 180

A polynomial with rational coefficients has roots 5 and -6i. (The i is an imaginary number not variable). What is the polynomial

mars1129 [50]

Answer:

The answer is { $x^{3}$ -(5) $x^{2}$ (36)× $x$ -(180)

Step-by-step explanation:

A polynomial with rational coefficients has roots 5 and -6i (There i is the

imaginary number not variable )

As we knew that imaginary no comes in pair . This means that if -6i is

one root then the other root will be 6i

So if we assume the lowest polynomial that is possible is given as

{ $x^{3}$ -(sum of all roots) $x^{2}$ +(roots taken two at a time)

$x$ -(product of all roots)

{ $x^{3}$ -(5+6i+(-6i)) $x^{2}$ +(5×6i +5×(-6i) +6i×(-6i))

$x$ -(5×6i×(-6i))

$i^2$ = -1

{ $x^{3}$ -(5) $x^{2}$ (36)× $x$ -(180)

The general case we assume that the three previous roots and rest roots

a4,a5,a6 ...............an

$x^n$ -(sum of all roots)× $x^{n-1}$ +(roots taken two at a

time) × $x^{n-2}$ - .......................................... (product of all roots)
