Answer: 2,977,200 miles per hour

Step-by-step explanation: This is true because taking that that is miles per second there is 60 seconds in a minute so times that by 60 and there are 60 minutes in an hour so times that last answer by 60 again which gives you the answer

Graph the system of linear equations. -1/2y=1/2x+5 and y=2x+2
sattari [20]

Answer:

The point for the given linear equations is (\dfrac{-2}{3} , \dfrac{2}{3})

Step-by-step explanation:

Given as :

The two linear equations are

First equation

\dfrac{-1}{2} y = \dfrac{1}{2} x + 5

Or,  \dfrac{1}{2} y + \dfrac{1}{2} x + 5 = 0

Taking LCM we get

y + x + 10 = 0          .......1

Second equation

y = 2 x + 2               ........2

Now solving both equation

Putting the value of y from eq 2 into eq 1

(2 x + 2) + x + 10 = 0

Or, 3 x + 12 = 10

Or, 3 x = 10 - 12

Or, 3 x = - 2

∴  x = \dfrac{-2}{3}

Now putting the value of x into eq 2

∵ y = 2 x + 2              

Or, y = 2 × \dfrac{-2}{3} + 2

Or, y = \dfrac{-4}{3} + 2

Or, y = \dfrac{- 4 + 6}{3}

∴   y = \dfrac{2}{3}

So, The points are (x , y ) = (\dfrac{-2}{3} , \dfrac{2}{3})

Now, plotting the points on x-y coordinate graph

Hence, The point for the given linear equations is (\dfrac{-2}{3} , \dfrac{2}{3}) Answer
