Answer:

[tex]f[2-f^{-1}(x)]=x[/tex]

Step-by-step explanation:

Given function is,

f(x) = [tex]\frac{x-1}{2}[/tex]

Equation form of the function will be,

y = [tex]\frac{x-1}{2}[/tex]

Interchange x and y,

[tex]x=\frac{y-1}{2}[/tex]

Solve for y,

y = 2x + 1

Therefore, inverse of the function 'f' will be,

[tex]f^{-1}(x)=2x+1[/tex]

Now [tex][2-f^{-1}(x)][/tex] = 2 - [2x + 1]

                          = -2x + 1

Value of [tex]f[2-f^{-1}(x)][/tex] = f(2x + 1)

From the given function,

f(2x + 1) = [tex]\frac{(2x+1)-1}{2}[/tex]

            = x

Therefore, value of  [tex]f[2-f^{-1}(x)]=x[/tex]

Answer:

∠ JHF = 69°

Step-by-step explanation:

Since HJ is a midline then it is parallel to EG , thus

∠ JHF and ∠ GEH are corresponding and congruent, then

7x + 62 = 79 - 10x ( add 10x to both sides )

17x + 62 = 79 ( subtract 62 from both sides )

17x = 17 ( divide both sides by 17 )

x = 1

Thus

∠ JHF = 7x + 62 = 7(1) + 62 = 7 + 62 = 69°

Answer:

7x + 62 = 180

7x= 180 - 62

x = 118 / 7

x = 16

7 × x = 7 × 16

112 + 62 = 174

(1/16)^2

b = 1/16

Consequently, the graph is correct; and the x values for the solutions are x = -2 and x = 0.

The solution to f(x) = g(x) is the value(s) of x that satisfy the equation. In other words, it is the value(s) of x that make f(x) equal to g(x).

The only problem here is determining which graph is correct:

f(x) is the same on both graphs;

g(x) = 2 |x + 2| is the absolute value graph of lxl stretched vertically two units to the left;

the "vertex" of lxl is (0, 0);

consequently, the first graph is correct; and the x values for the solutions are x = -2 and x = 0.

Answer:

Step-by-step explanation:

Answer:

x = -84

y = -21

Step-by-step explanation:

4 - y = 17

4y = x

Use the first equation to solve for y

4 - y = 17

y = 4 -  17

y = -21

In the second equation, get y on its own.

4y = x

y = x/4

Substitute the new second equation into the new first equation

-21 = x/4

-21 * 4 = x

x = -84

Answer:

Puppy's current weight = 33 pounds.

Step-by-step explanation:

The weight of Ray's puppy 1 year ago = 8 pounds

All we need is to add the 8 pounds to 25 to determine the current weight.

i.e.

current weight = 8 + 25

                         = 33 pounds

Therefore, puppy's current weight = 33 pounds.

Answer:

The total number of votes cast in the election was 11,141.

Step-by-step explanation:

To determine the number of negative votes in the voting, taking into account that the ratio of votes between positive and negative is 8 to 5 and that there were 6,856 positive votes, it is necessary to perform the following calculation:

6.856 / 8 x 5 = X

857 x 5 = X

4.285 = X

Therefore, there were 4,285 negative votes in the election. So, since 4,285 + 6,856 equals 11,141, the total number of votes cast in the election was 11,141.

Answer:

1 1/3 bags of chocolate chips

Step-by-step explanation:

If Alana has 2 1/4 bags of chocolate chips that she wants to use in 3 batches of chocolate chip cookies, then we can say;

2 1/4 bags of cookies = 3 batches of chips

To determine how much of the chocolate chips will she use in each batch of cookies, we can say;

1 bag of cookies = x batches of chips

Equating both expressions

2 1/4 bags of cookies = 3 batches of chips

1 bag of cookies = x batches of chips

Cross multiply

2 1/4 x = 3

9/4 x = 3

9x/4 = 3

9x = 12

x = 12/9

x = 4/3

x = 1 1/3

Hence Alana will need 1 1/3 bags of chocolate chips

We have the points ( -2 , 4) and (3 , -5) so plug in the values in the formula:

[tex]m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{-5-4}{3-(-2)}\\\\m=\frac{-9}{5}\\[/tex]

so the slope(m) equals -9/5

Answer:

593.14 m

Step-by-step explanation:

Given that :

Length of rig visible above water surface (sea. Level) = 74.98m

Length of rig below surface of water (sea level) = 518.16 m

The total height of the rig:

The surface of water is usually regarded as a zero point ;

Hence. The total height of rig will be the sum of the height above sea level and the length below water surface

=(74.98 + 518.16) m

= 593.14 m
