Answer:

\/

Step-by-step explanation:

Inverse of 1.5x+4: 2(x-4) /3

Slope of 1.5x+4: m=1.5

First, change it to 1.50x + 4 = 0.

then subtract 4 on each side
( 1.50x = -4).

then divided by 1.50.
x= 2.666666

The distance between the cities Chicago and Toronto is 540 miles. A motorcycle's speed is 48 mph. For a car, it takes 2.25 hours
serious [3.7K]

Answer:

5 hours

Step-by-step explanation:

given :

Distance between the cities = 540 miles

Speed of motorcycle =48 mph

TO CALCULATE THE TIME TAKEN BY MOTORCYCLE TO COVER THE TOTAL DISTANCE WE USE THE FORMULA :

\frac{DISTANCE}{SPEED}

By putting given values in the formula we get :

\frac{540}{48}

= 11.25 hours

Now, We are given that for a car to cover the same distance it takes 2.25 hours less than the time taken by motorcycle

⇒ 11.25 hours - 2.25 hours

⇒ 9 hours

Thus , Time taken by car to cover the same distance is 9 hours .

Now to calculate speed of car by using formula:

\frac{distance}{time}

\frac{540}{9}

= 60 mph

Let t be the time taken to meet if they start moving towards each other.

So distance covered by motorcycle in t hours is

speed\times time

= 48t miles

Distance covered by car in t hours is

speed\times time

= 60t miles

⇒ 60t + 48t =540

⇒ 108t = 540

⇒ t= 5 hours

Therefore, time taken to meet if they start moving towards each other is 5 hours.

Consider an airplane heading due east at 150 miles/hour relative to the air. The wind is blowing at 7.1 miles/hour at 45º south
sergij07 [2.7K]

We have

<span>Va(airplane)=150  East</span>

Vw(wind)=7.1 South East

<span>
</span><span>resulting vector R</span>

airplane

Vax=150    Vay=0   it only has component x 


Wind
Vwx=7.1*cos45=5.02

Vwy=7.1*sin45=-5.02 is negative because is South direction

 |R|=(Rx^2+Ry^2) ^0.5

Rx=150+5.02=155.02

Ry=0-5.02=-5.02

<span>|R|=155.10 miles/hour South East</span>

Determine angle θ

Rx=R*cos(θ)

<span>Cos(θ)=Rx/R</span> <span>Cos(θ)=155.02/155.10=0.9995</span>

 θ =arc cos Rx/R θ =1.8119 º

 Rx represents the component in the East direction of the resultant force. Your contribution is given by both, the force of the plane and the wind. The contribution of the wind makes the airplane's speed greater

 Ry represents the component in the South direction of the resulting force Its contribution is exclusive of the wind since the airplane has no component in this direction

 |R| the force resulting from the combined action of the force of the plane and the force of the wind

 θ represents the angle that forms the resultant force with respect to the x axis or east direction

which ordered pairs are a solution to the question y=8× select all that apply (-1,-7)(2,16)(1,8)(-2,-6)​
abruzzese [7]

Answer:

(2,16) , (1, 8)

Step-by-step explanation:

(-1,-7), x = -1 and y = -7

plug in

y = 8x

-7 = 8 * -1

-7 = -8, false

(2,16), x=2 and y = 16

plug in

y= 8x

16 = 8 * 2

16 = 16, so it is a solution

(1,8), x = 1 and y = 8

plug in

y = 8x

8 = 8 * 1

8 =8 , so it is a solution

(-2,-6), x = -2, y = -6

plug in

y = 8x

-6 = -2 * 8

-6 = -16, false
