Answer:

2, 0.5 and 0.25.

Step-by-step explanation:

The nth term an = a1r^(n-1)  where a1 = first term and r = the common ratio.

The sum to infinity = a1/(1-r)  for  -1 < r < 1.

So we have:

Second term a2 = 1 = a1(r)(2-1) = a1r and

4 = a1/(1 - r)

From the first equation:

a1 =1/r

So substituting in the second equation:

4 = 1/ r / (1 - r)

4 = 1 / r - r^2

4r - 4r^2 = 1

4r^2 - 4r + 1 = 0

(2r - 1)(2r - 1) = 0

r = 0.5

So the first term  a1 = 1/ r =1/0.5 = 2.

The third = 1*0.5 = 0.5

and the 4th = 0.5*0.5 = 0.25.

The simplified expression is 15 + 2i.

In conclusion, the simplified expression (7 - i) + (5 + 3i) - (-3 + 2i) simplifies to 15 + 2i.

Answer:

y=3    x= -5/2

Step-by-step explanation:

simultaneous equations

2x + 4y = 7  ------ eq 1

-2x + 3y = 14 --------eq2

(different signs add)

(eq 2 + eq 1)

-2x +(-2x) = 0

4y+3y = 7y

7+14 = 21

7y= 21

(divide both sides by 7)

y= 21/7= 3

2x + 4(3) = 7

2x+ 12=7

2x = 7-12

2x = -5

x= -5/2

Answer:

32 ounces

Step-by-step explanation:

8x4=32

There are 32 ounces of stuffing in 4 of the pillow.

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

A pillow contains 8 ounces of stuffing.

Now,

Since, A pillow contains 8 ounces of stuffing.

So, The amount of ounces in 4 of the pillow = 8 x 4

                                                                    = 32

Thus, There are 32 ounces of stuffing in 4 of the pillow.

Answer: x=10; y=-1

Step-by-step explanation:

To solve this via elimination:

get rid of the y's like this:

Answer:

C

Step-by-step explanation:

The diagonals of a rectangle are congruent, then

5x - 31 = 2x + 11 ( subtract 2x from both sides )

3x - 31 = 11 ( add 31 to both sides )

3x = 42 ( divide both sides by 3 )

x = 14

Then

RT = 2x + 11 = 2(14) + 11 = 28 + 11 = 39

The diagonals are each 39 units

The binomial 14[tex]x^{2}[/tex] - 35x can be factored as 7x(2x+5)

Step-by-step explanation:

When factoring, you want to factor each constant or variable by their greatest common factor (or GCF). Since [tex]14x^{2}[/tex] and [tex]35x[/tex] has a greatest common factor of 7x, factor each term by 7x and you'll get [tex]7x(2x+5)[/tex].

Answer:

THE ANSWER IS B

Step-by-step explanation:

IT JUST MAKES SENSE TO CHOOSE B

The option D pairs of functions are inverses of each other.

A relationship between a group of inputs and one output is referred to as a function. In plain English, a function is an association between inputs in which each input is connected to precisely one output. A domain, codomain, or range exists for every function. Typically, f(x), where x is the input, is used to represent a function.

To find the inverse of a function, write the function f(x) as a function of x and then solve for x as a function of f(x).

For option A,

f(x) = 2 + ∛x

To solve for x,

∛x = f(x) - 2

x = (f(x) - 2)³

That is also the inverse So,

g(x) = (x -2)³ "Not correct"

For Option B,

f(x) = x/6 + 8

To solve for x,

x/6 = f(x) -8

x = 6f(x) - 6 *8

That is also the inverse So,

g(x) = 6x - 6 *8 "Not correct"

For Option C,

f(x) = 7/x - 9

To solve for x,

7/x = f(x) +9

x = [tex]\frac{7}{f(x) +9}[/tex]

That is also the inverse So,

g(x) = [tex]\frac{7}{x +9}[/tex] "Not correct"

For Option D,

f(x) = 5x - 11

To solve for x,

5x= f(x) + 11

x = (f(x) + 11)/5

That is also the inverse So,

g(x) =(x + 11)/5 "correct"

Thus, the option D pairs of functions are inverses of each other.
