Can someone help (Geometry)

Answer:

[tex](fog)(x) = f(g(x)) \\ = 7(4 - 2x) - 7 \\ = 28 - 14x - 7 \\ = 21 - 14x \\ = - 14x + 21[/tex]

[tex](gof)(x) = g(f(x)) \\ = 4 - 2(7x - 7) \\ = 4 - 14x + 14 \\ = 18 - 14x \\ = - 14x + 18[/tex]

I hope I helped you^_^

11.8 mps

Answer:

the answer is 6.5 because 8 1/2 - 15 is 6 1/2 or 6.5

Answer:

1/2

Step-by-step explanation:

..

Answer: 12 inches

Step-by-step explanation:

1: place the units in the ratios (make sure they match, you should label the numbers in your work so you know put the units in right unlike what i did in my work) and cross multiply

2: divide both sides by 924 in. to get x by itself

3. x = 12 in.

Answer:

[tex] \boxed{x = 7} [/tex]

Step-by-step explanation:

Given:

We can illustrate this relationship as:

(2x + 1)

___↑___

| |

A — B — C

|____|___|

↓ ↓

(x + 4) (2x – 10)

_______________________________

When you are given an algebraic expression for the length of a segment, you can solve for that value by knowing that the sum of two segments AB + BC = AC.

Thus:

(x + 4) + (2x – 10) = (2x + 1)

[Regroup terms]

(x + 2x) + (4 – 10) = (2x + 1)

[Simplify]

(3x – 6) = (2x + 1)

[subtract 2x from both sides to isolate the variable]

(3x – 6) – 2x = (2x + 1) – 2x

[Regroup terms]

(3x – 2x) – 6 = (2x – 2x) + 1

x – 6 = 1

[Add 6 to both sides to isolate the constant]

x – 6 + 6 = 1 + 6

[Simplify]

x = 7

Slope of a function is 0, which depicts that it is a line parallel to x - axis, hence it will be a horizontal line .

Therefore, correct option is

B. The line is horizontal.

Answer:

Step-by-step explanation:

All of them are rational.

Irrational numbers go on forever, like 10/3=3.33333333...

Pi is an irrational number because it goes on forever.

Answer:

First, we can find the formula for the subtraction without substitution:

Step-by-step explanation: −9x+3=(−3)(3x)+(−3)(−1)                               −9x+3+9x=−9x+3+9x                                                                                                   3-3=3-3                                                                                                                    0=0                                                                    

Answer:

52

Step-by-step explanation:

Answer for this question as follows

2–2=0

5–2=3

13–5=8

28–13=15

As we observe the difference of the difference is

3–0=3

8–3=5

15–8=7

Here the differnce is increasing by two

X-15=7+2=9

X=24

So the required answer is 28+24=52

Answer:

[tex]v=5[/tex]

Explanation:

The equation is asking for multiplication (13 * v), and the opposite of multiplication is division. So if we divide 65 by 13, we find 5.

13 * 5 = 65

Answer:

v = -5

Step-by-step explanation:

1. Pull out like factors :

  -13v - 65  =   -13 • (v + 5)

2. Solve :    -13   =  0

This equation has no solution.

A a non-zero constant never equals zero.

3. Solve  :    v+5 = 0

Subtract  5  from both sides of the equation :

                     v = -5

Answer:

n(A) can also be known as cardinal number or the total number of elements in A

n(A) = 5

Answer:

3.57

Step - step

So the hundredth is the 6

you need to look the next number after 6

it is 8 which is more than 5 so

the hundredts number which is 6 need to plus one(+1)

3.56 + 0.01

= 3.57

and the number after seven No need to do it

Answer:

f⁻¹(x) = 8x - 1

Step-by-step explanation:

Swap the positions of y (f(x)) and x and solve for y.

[tex]x=\frac{y+1}{8}\\\\8(x)=\frac{y+1}{8}(8)\\\\8x=y+1\\\\8x-1=y+1-1\\\\8x-1=y[/tex]

Answer:

12x/6

Step-by-step explanation:

6 is being divided into 12x so you ask yourself what is 12x divided by 6 and that is your algebraic expression.

Answer:

x = 26

Step-by-step explanation:

[tex]x - 14 = 12[/tex]

[tex]x - 14 + 14 = 12 + 14[/tex]

[tex]x = 12 + 14[/tex]
