**Step-by-step explanation:**

Since we need to find the geometric sequence ,

For this we find the **" common ratio"** :

On the other hand, in options 'B' , 'C' and 'D' , there is no common ratio,

**Hence, Option 'A' is correct.**

To determine the value of x in our equation, "5x = 16", we need to divide both sides by 5 to get x by itself.

Divide 5 and 16 by 5.

5x/5 = x, 16/5 = 3.2.

x = 3.2

I hope this helps!

If you do the same calculations for B, C and D you'll get the correct answers

It looks like Domain B matches Range 1:- 52 / 2.5 = 20.8, 56/2.5 = 22.4

QUESTION POSTED AT 28/03/2020 - 10:59 AM

I'm assuming the 5x should be a 5y.

4x - 2y = 16

4x - 5y = 8

I would use the elimination method since the coefficients on the x variable are the same.

Subtract the second equation from the first equation.

4x - 2y = 16

-(4x -5y = 8)

-------------------

3y = 8

y = 8/3

Plug */3 back in for y and solve for x.

4x -2y = 16

4x -2(8/3) = 16

4x - (16/3) = 16

add (16/3) to both sides.

4x = (16/3) + (48/3)

4x = (64/3)

multiply both sides by (1/4) to clear the 4

x = (64/3)(1/4)

x = 16/3

(16/3, 8/3)

4x - 2y = 16

4x - 5y = 8

I would use the elimination method since the coefficients on the x variable are the same.

Subtract the second equation from the first equation.

4x - 2y = 16

-(4x -5y = 8)

-------------------

3y = 8

y = 8/3

Plug */3 back in for y and solve for x.

4x -2y = 16

4x -2(8/3) = 16

4x - (16/3) = 16

add (16/3) to both sides.

4x = (16/3) + (48/3)

4x = (64/3)

multiply both sides by (1/4) to clear the 4

x = (64/3)(1/4)

x = 16/3

(16/3, 8/3)

slope = (16 - 0)/(4 - 0)

slope = 16/4

slope = 4

at x = 4, y = 16 (x2,y2)

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

CPCTC stands for : corresponding parts of congruent triangles are congruent.

16) A) ∠GAE≅∠GEA

17) if y° =22° so angle A = 2y=then angle A=44°

Since this triangle ABC is isosceles (AB=AC given), then Angle B= Angle C

In a triangle we know that the sum of all angles =180°, the 44°+2C=180

& C= (180-44)/2 = 68 (C)

18) C)BC≅CE is not necessarily true

19) Reflexive Property; Given

20) Right Triangles ABC & AED are congruent::

CB=ED (given)

Angle C = D (given)

Angle B = E =90° (given)

The 2 triangles are congruent ASA & AC = AD

Now we have the equalities:

1) BC=ED ===> x=y-1

And

2) AC=AD ===> 3x-2 = 2y+1

Let' arrange these 2 equations:

x-y = -1

3x-2y =3

Solving this system with 2 variables x & y gives: X=5 & Y=6 (D)
