The rotation is 90° counter clockwise.

<u>Step-by-step explanation:</u>

Triangle GHJ has the points G(2,5), H(3,3) and J(1,4)

And the coordinates changes after 90° counterclockwise rotation,

the points are changed from (x,y) to (-y, x) ,

so the triangle G'H'J' has the points G'(-5,2), H'(-3,3), J'(-4,1).

What would the equation be ?
Vikentia [17]

Answer:

y = 4/5x-18/5

Step-by-step explanation:

First we find the slope from the given points (-3,-6) (2,-2)

m = (y2-y1)/(x2-x1)

m = (-2 - -6)/(2 - -3)

   (-2+6)/( 2+3)

  4/5

The slope intercept form of an equation is

y = mx +b  where m is the slope and b is the y intercept

y = 4/5 x +b

Substitute a point into the equation to find b

-6= 4/5(-3) +b

-6= -12/5 +b

Add 12/5 to each side

-6 +12/5 = -12/5 +12/5 +b

Get a common denominator

-30/5 + 12/5 = b

-18/5 =b

The equation is

y = 4/5x-18/5

How long does it take an airplane flying at a speed of 600 miles per hour to fly 3,000 miles?
ser-zykov [4K]

Answer:

<u>Option D is answer.</u>

Step-by-step explanation:

Hi there!

From the question;

Speed (s) = 600 miles/hr

Distance (d) = 3000 miles

Time (t) = ?

We know that;

Speed (s) = \frac{Distance(d)}{Time (t)}

600 = \frac{3000}{t}

t = \frac{3000}{600}

Therefore, it will take 5 hours to fly 3000 miles.

Hope its helps!
