express as a single logarithm 3 loga (2x+1) - 2 loga (2x-1) +2

Answer:

B and C

Step-by-step explanation:

All others have higher factors than 4

Answer:

B,(4,8) &C,(8,12)

Step-by-step explanation:

A,(2,4)=2=2

4=2^2(GCF of 2&4 is 2)

B,(4,8)=4=2^2

8=2^3(GCF of 4&8 is 4)

C,(8,12)=8=2^3

12=2^2*3(GCF of 8&12 is 4)

D,(8,16)=8=2^3

16=2^4(GCF of 8&16 is 8)

E,(12,24)=12=2^2*3

24=2^3*3(GCF of 12&24 is 12).

i hope it helps you

Answer:

Step-by-step explanation:

Explaining the Basic Concept:

This is a piecewise function, which means that it is made up of several different functions which all have different domains

In this question, we have 3 'pieces' in our piecewise function

the domain of each piece is:

1.   x < -1

2.  -1 ≤ x ≤ 2

3.  x > 2

we will use the function related with the respective domain

Finding the values of the function:

h(-4)

Here, our input value is -4

we notice that -4 is in part of the first domain

therefore, -4 is in the domain of the first function

So, we will use the first function

h(x) = -(x/4) + 2           (for x < -1)

replacing x with -4

h(-4) = -(-4/4) + 2

h(-4) = 1 + 2

h(-4) = 3

h(1):

Here, our input value is 1

we notice that 1 is a part of the second domain

Hence, 1 is in the domain of the second function

So, we will use the second function

h(x) = -(x-1)² + 2            (for -1 ≤ x ≤ 2)

replacing x with 1

h(1) = -(1-1)² + 2

h(1) = -(0)² + 2

h(1) = 2

h(2):

Here, out input value is 2

We notice that 2 is a part of the second domain

Hence, 2 is a part of the domain of the second function

So, we will use the second function

h(x) = -(x-1)² + 2            (for -1 ≤ x ≤ 2)

replacing x with 2

h(2) = -(2-1)² + 2

h(2) = -(1)² + 2

h(2) = - 1 + 2

h(2) = 1

Therefore:

h(-4) = 3

h(1) = 2

h(2) = 1

its nine bruhhhhhhhhhhhhh

Answer:

there are 8 girl students

Step-by-step explanation:

28-4= 24

28 divided by 3 is 8

8x2=16

16+4=20

20+8= 28

therefore... there are 8 girls in the class

Answer: 5) 2, -8, 32, _,_

I believe that it would be -64, then 128

Step-by-step explanation:

Bc its positive then negative and its being multiplied by -4 each time so when you mutiply a negative to a negative its a positive which is were the positives and negatives come from. :)

Answer:

b, controlled variables are constant and unchanged

A controlled variable is what is held constant. When doing an experiment, it is ideal to only focus on one variable at a time while keeping everything else in check. This way you can compare two items effectively.

In contrast, a manipulated variable is one that is intentionally changed to see how it affects the subject. For example, if you're testing various fertilizers, then the fertilizer brand would be the manipulated variable. The soil, moisture, amount of sunlight, and other environmental factors are kept the same (each subject gets the same about of each) making them to be controlled variables.

Answer:

  y = -5/4x -19

Step-by-step explanation:

It is often convenient to simplify a point-slope form of the equation.

  y = m(x -h) +k . . . . . line with slope m through (h, k)

  y = -5/4(x -(-8)) -9 . . . . fill in given values

  y = -5/4x -10 -9

  y = -5/4x -19

Answer:

x=6

Step-by-step explanation:

The picture is a little unclear but I hope this is true...

To find the perimeter you need to add the sides of the triangles and the question says that the perimeters of the triangles are equal. So,...

(2x+4)+(2x)+(2x+3)=(3x+1)+(2x)+(2x)

2x+4+2x+2x+3=3x+1+2x+2x

4+2x+3=3x+1

7+2x=3x+1

2x-3x=1-7

-x=-6

x=6

Answer:

[tex]Solution: f(x)\ge-5\\Interval:[-5,\infty)[/tex]

Step-by-step explanation:

Equation: [tex]\frac{1}{4} x^2-5 = y[/tex]

1). [tex]\frac{1}{4} x^2-5 = y[/tex] →[tex]\frac{x^2}{4}-5=y[/tex]

2). [tex]\frac{x^2}{4}-5=y[/tex] ∴ [tex]a=\frac{1}{4}, b=0, c=-5[/tex]

3). [tex]x_v=-\frac{b}{2a}[/tex]

         [tex]=-\frac{0}{2(\frac{1}{4})}[/tex]

         [tex]=0[/tex]

4). now plug [tex]x_v[/tex] into [tex]y_v[/tex]

[tex]y_v=\frac{0^2}{4}-5[/tex]

    [tex]=-5[/tex]

5). Minimum (0,-5) ∴ [tex]f(x)\ge-5[/tex]

Answer:

Answer:

l=6

b=30

Step-by-step explanation:

b=5l

perimeter= 72

2(l+b)= 72

l+b= 36

l+5l= 36

6l= 36

l= 6

b=5l= 6*6= 30

Answer:

100.40

Step-by-step explanation:

if 6 members has paid, then the remaining 8 will be 8 x 12.55 = 100.4

Answer:

The answer is $100.40

Step-by-step explanation:

ok. their are 14 members. 6 members payed their dues in week 1. so, subtract 6 from 14.    14 - 6 = 8.    Now, the due is $12.55. 8 members payed their dues in week 2, so multiply 8 by 12.55.     8 x 12.55 = 100.50    the answer SHOULD be $100.50 i would think, but there is not an option for that. so, i would pick option 4, because that is .10 off from 100.50. Good luck!!

i asked alexa so yeaaa

Problem 1

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

Explanation:

Add the equations straight down.

The x terms add to 5x+(-3x) = 2x

The y terms cancel out since 3y+(-3y) = 0y = 0

The right hand sides add to -7+3 = -3

After adding the equations you should get 2x = -4 which solves to x = -2

=====================================================

Problem 2

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

Explanation:

Since 5x = 0, this means x = 0 after dividing both sides by 5.

Use this to find y

y = -4x+4

y = -4(0)+4

y = 4

If you want the value of z, then

x = -3y+z+6

0 = -3(4)+z+6

0 = z-6

6 = z

z = 6

Answer:

In math, prime numbers are whole numbers greater than 1, which have only two factors – 1 and the number itself. Prime numbers are divisible only by the number 1 or itself. For example, 2, 3, 5, 7, and 11 are the first few prime numbers.
