Triangle GHJ and its image, triangle G’H’J’, are graphed on the coordinate grid below. On a coordinate plane, triangle G H J has

Ipatiy [6.2K]

The rotation is 90° counter clockwise.

Step-by-step explanation:

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).

On a partly cloudy day, Derek decides to walk back from work. When it is sunny, he walks at a speed of s miles/hr (s is an integ

Setler [38]

Answer: $\frac{1}{7}$

Step-by-step explanation:

Given

sunny day speed= s mph

Rainy day speed=s+1 mph

Derek average speed =2.8 miles/hr

s<2.8<s+1

so on sunny day speed must be 2 mph

and on rainy day speed must be 3 mph

$v_{avg}=\frac{distance}{time\ taken}$

Let x be the distance traveled in sunny and y be the distance traveled in rainy weather

$2.8=\frac{x+y}{\frac}{x}{2}+\frac{y}{3}}$

Let $\frac{x}{y}=z$

$2.8=\frac{z+1}{\frac{z}{2}+\frac{1}{3}}$

$z=\frac{1}{6}$

Fraction of distance traveled on sunny weather

$\frac{x}{x+y}=\frac{z}{z+1}=\frac{1}{7}$
