The answer to your question is b
This is because triangle pqy is definitely not an option as it is far too small to be similar to the other triangles. So, we have crossed off two options
Now, we have to determine which way p, or in what order they have named the triangles.
They name one triangle as CGW. This starts from the corner then goes to the second longest side, and triangle HFB starts from a corner and goes to the second longest side.

Answer:

Step-by-step explanation:

Try to imagine walking the path from over G to W, then do the same walk with HFB. And the lengths you have to walk, the degrees you have to turn are the same. they are congruent.

Reika [66]

Answer:

The answer is 2

Step-by-step explanation:

Rate of change of function is given by :

$\frac{(f(x_{2})-f(x_{1}))}{x_{2}-x_{1}}$

For function y = 6,

rate of change =

$=\frac{(f(x_{2})-f(x_{1}))}{x_{2}-x_{1}}\\=\frac{6-6}{x_{2}-x_{1}}\\=0$

because the function is independent of x.

For function y = 2·x + 7,

rate of change =

$=\frac{(f(x_{2})-f(x_{1}))}{x_{2}-x_{1}}\\=\frac{2\cdot x_{2}+7-2\cdot x_{1}-7}{x_{2}-x_{1}}\\=\frac{2\cdot x_{2}-2\cdot x_{1}}{x_{2}-x_{1}}\\=\frac{2\cdot (x_{2}-x_{1})}{x_{2}-x_{1}}\\=2$

So, the rate of change of 2 is greater than rate of change of function 1 by 2 - 0 = 2.

Determine the equation of the line passing through the points (3,1) and (5,−1).

katrin [286]

Answer:

y=-x+4

Step-by-step explanation:

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

m=(-1-1)/(5-3)

m=-2/2

m=-1

y-y1=m(x-x1)

y-1=-1(x-3)

y-1=-x+3

y=-x+3+1

y=-x+4
