Which of the following represents a geometric sequence? A. 1/4, 1/4, 1/4, 1/4 B. 1/4, 1/5, 1/6, 1/7 C. 1/4, 1, -4, 16 D. 1/4, -4, 1/4, -4

Answer:  Option 'A' is correct.

Step-by-step explanation:

Since we need to find the geometric sequence ,

For this we find the " common ratio" :

\frac{a_2}{a_1}=\frac{a_3}{a_2}\\\\\frac{\frac{1}{4}}{\frac{1}{4}}=\frac{\frac{1}{4}}{\frac{1}{4}}\\\\1=1

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

Hence, Option 'A' is correct.

QUESTION POSTED AT 28/03/2020 - 11:22 AM

What is the value of x? 5x = 16

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!

Match each given domain of the function f(x)=x/2.5 with its corresponding range. A. {40,45,50,55,60} B. {52,56,63,67,71} C. {37,46,49,55,57} D. {44,51,59,66,67} 1. {20.8,22.4,25.2,26.8,28.4} 2. {16,18,20,22,24} 3. {17.6,20.4,23.6,26.4,29.2} 4. {14.8,18.4,19.6,22,22.8}

Domain A matches Range 2  because 

40/2.5 = 16 , 45/ 2.5 = 18   and so on  -all 5 work ou.

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  

- I think I can leave you to finish this off .

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

Someone please help me!? 4x-2y=16 4x-5x=8 Please enter answer as an ordered pair.

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)

QUESTION POSTED AT 28/03/2020 - 10:45 AM

A student solves the following equation for all possible values of x: 8/x+2 = 2/x-4 His solution is as follows: Step 1: 8(x – 4) = 2(x + 2) Step 2: 4(x – 4) = (x + 2) Step 3: 4x – 16 = x + 2 Step 4: 3x = 18 Step 5: x = 6 He determines that 6 is an extraneous solution because the difference of the numerators is 6, so the 6s cancel to 0. Which best describes the reasonableness of the student’s solution? a) His solution for x is correct and his explanation of the extraneous solution is reasonable. b) His solution for x is correct, but in order for 6 to be an extraneous solution, both denominators have to result in 0 when 6 is substituted for x. c) His solution for x is correct, but in order for 6 to be an extraneous solution, one denominator has to result in 0 when 6 is substituted for x. d) His solution for x is incorrect. When solved correctly, there are no extraneous solutions

The correct answer is:
C) his solution for x is correct, but in order for 6 to be an extraneous solution, one denominator has to result in 0 when 6 is substituted for x.

Explanation:
To solve this rational equation, we cross multiply:
8*(x-4)=2*(x+2).

Using the distributive property, we have
8*x-8*4=2*x+2*2;
8x-32=2x+4.

Subtract 2x from each side:
8x-32-2x=2x+4-2x;
6x-32=4.

Add 32 to each side:
6x-32+32=4+32;
6x=36.

Divide both sides by 6:
 \frac{6x}{6} = \frac{36}{6} ;
x=6.

Extraneous solutions are solutions that come about in the problem but are not valid solutions to the problem; the only values of x that would give this sort of answer are -2 and 4, since these are the two values that would make one of the denominators 0 (we cannot divide by 0).

Tell why UW≅UW and ∠UVW≅∠WXU. look at the fourth picture. A) Reflexive Property; Given B)Given; Reflexive Property C)Reflexive Property; Transitive Property D)Transitive Property; Reflexive Property 20) Find the values of x and y that make these triangles congruent by HL. look at the fifth picture. A) x=3, y=4 B)x=6, y=5 C)x=4, y=3 D)x=5,y=6

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)
