Answer: Second option.

Step-by-step explanation:

Given the function f(x), which is:

[tex]f(x)=x[/tex]

And given the function g(x), which is:

[tex]g(x)=2[/tex]

You need to substiute the function [tex]g(x)=2[/tex]  into the function  [tex]f(x)=x[/tex] in order to find [tex](fog)(x)[/tex].

Therefore, through this procedure, you get this answer:

[tex](fog)(x)=(2)[/tex]

[tex](fog)(x)=2[/tex]

You can observe that this matches with the second option.

For this case we have the following functions:

[tex]f (x) = x\\g (x) = 2[/tex]

We must find [tex](f_ {0} g) (x).[/tex]

By definition of composite functions we have to:

[tex](f_ {0} g) (x) = f (g (x))[/tex]

We substitute g (x) into f (x), then we have:

[tex]f (g (x)) = 2[/tex]

Answer:

[tex]f (g (x)) = 2[/tex]

Option B

Answer:

Part 1) h(g)=-4+g ----> the input is g

Part 2) f(h)=-h-7 -----> the input is h

Part 3) g(f)=-2f -----> the input is f

Step-by-step explanation:

Part 1) we have

h(g)=-4+g

we know that

The input  is the independent variable and the output is the dependent variable

so

the output is h(g) or 4+g

the input  is the variable g

Part 2) we have

f(h)=-h-7

we know that

The input  is the independent variable and the output is the dependent variable

so

the output is f(h) or h-7

the input  is the variable h

Part 3) we have

g(f)=-2f

we know that

The input  is the independent variable and the output is the dependent variable

so

the output is g(f) or 2f

the input  is the variable f

Answer: Questions are in different places than other people screen.

h(g) = -4+g     -       The input is G

g(f) = 2f          -       The input is F

f(h) = h - 7      -       The input is H

ANSWER

C) (6,-8)

EXPLANATION

The equations are:

[tex]y = \frac{1}{3}x - 10[/tex]

and

[tex]2x+y=4[/tex]

We substitute the first equation into the second equation to get:

[tex]2x + \frac{1}{3}x - 10 = 4[/tex]

We multiply through by 3 to get:

[tex]6x + x - 30= 12[/tex]

Group similar terms,

[tex]6x + x = 30 + 12[/tex]

[tex]7x = 42[/tex]

Divide both sides by 7 to get,

[tex]x = \frac{42}{7} = 6[/tex]

Put this value of x into the first equation to get;

[tex]y = \frac{1}{3} (6) - 10[/tex]

[tex]y = 2 - 10 = - 8[/tex]

Answer:

(- [tex]\frac{9}{2}[/tex], [tex]\frac{1}{2}[/tex] )

Step-by-step explanation:

Using the midpoint formula

Given 2 points (x₁, y₁ ) and (x₂, y₂ ), then midpoint is

([tex]\frac{x_{1}+x_{2}  }{2}[/tex], [tex]\frac{y_{1}+y_{2}  }{2}[/tex])

with (x₁, y₁ ) = (- 1, 5) and (x₂, y₂ ) = (- 8, - 4), then midpoint

= ([tex]\frac{-1-8}{2}[/tex], [tex]\frac{5-4}{2}[/tex] )

= ( - [tex]\frac{9}{2}[/tex], [tex]\frac{1}{2}[/tex] )

Answer:-4.5,0.5

Step-by-step explanation:midpoint =x1+x2/2, y1+y2/2

-1+-8/2=x,-4+5/2=y

-9/2=x,1/2=y

-4.5=x, 0.5=y

Answer:

The numbers are -16,-15 and -14

Step-by-step explanation:

Let

x ----> the first number

x+1 ----> the second number

x+2 ---> the third number

we know that

(1/4)x+(1/5)(x+1)=(1/7)(x+2)-5

Multiply by (4*5*7) both sides

35x+28(x+1)=20(x+2)-140*5

35x+28x+28=20x+40-700

43x=-688

x=-16

so

x+1=16+1=-15

x+2=-16+2=-14

The numbers are -16,-15 and -14

Answer:

solution = (1.-2)

Step-by-step explanation:

put x= 1 and y = -2 in this system  :  y=-4x+2 and y + 2x = 0

you have :  - 2 = - 4(1)+2  and -2 +2(1)=0

-2=-2 and 0=0 .....right

The required solution of the given system of equations is (1, -2), and a graph of the solution has been shown.

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

Here,
y=-4x+2 - - - -(1)
y + 2x = 0 - - - (2)

Equating equations,
-4x +2 = -2x
x =  1

Put x = -2 in equation 1
y = -4(1) + 2
y = -2

Thus, the required solution of the given system of equations is (1, -2).

since its complementary, the sum if both angles equals 90 degrees.

you do x+x+10 so you combine like terms to get 2x+10=90

then you subtract 10 to get

2x=80

and divide by 2

x=40

angle a=50 degrees

angle b=40 degrees

Answer:

m < A = 50 degrees, m < B = 40 degrees.

Step-by-step explanation:

Complementary angles sum to 90 degrees, so:

A + B = 90

As A = B + 10:

B + 10 + B = 90

2B = 80

B = 40.

So A = 40 + 10 = 50.

Answer:

The last one

Step-by-step explanation:

Your equation is p(x) = |x - 1|

The function equation can be represented by f(x) = a|x - h| + k

To find the vertex, you have to find (h,k)

In the equation p(x) = |x - 1|, 1 is h [since its (+h,k) not (-h,k)]

k is 0 since there is no +k after |x-1|.

So, your vertex will be at (1,0)

Thus, the answer is the last graph.

[I also graphed it on a graphing calculator so you can check. :) ]

The vertex will be at (1, 0).

Functions of graphs

The given equation is p(x) = |x - 1|

The function equation can be defined by f(x) = a|x - h| + k

To calculate the vertex, you have to identify (h, k)

In the given equation p(x) = |x - 1|, 1 exists h

[since its (+h, k) not (-h, k)]

k exists 0 since there does not exist +k after |x-1|.

So, the vertex will be at (1, 0).

Therefore, the graph represents the function p(x) = |x – 1| is option (d).

Answer:

c)

Step-by-step explanation:

-2 is the slope so that y equals -2x and the y intercept is positive 4 so that the equation is y=-2x+4

Answer:

c)  y = -2x+4

Step-by-step explanation:

The slope intercept form of a line is

y = mx+b  where m is the slope and b is the y intercept

Substituting in

y = -2x +4

To solve this you must use Pythagorean theorem:

[tex]a^{2} +b^{2} =c^{2}[/tex]

a and b are the legs (the sides that form a perpendicular/right angle)

c is the hypotenuse (the side opposite the right angle)

In this case...

a = 5

b = 8

c = x

^^^Plug these numbers into the theorem

[tex]5^{2} +8^{2} =x^{2}[/tex]

simplify

25 + 64 = [tex]x^{2}[/tex]

Answer:

Step-by-step explanation:

The total number of shoes they share is

4 + 5 + 3 = 12

Kyra: 4/12 = 0.333333

Tennis Shoes: There are now 11 shoes. 5/11 = 0.46

The probability that Kyra selects a pair of sandals and her sister selects a pair of tennis shoes is 3/20.

To find the probability that Kyra selects a pair of sandals and her sister selects a pair of tennis shoes, we need to determine the total number of possible outcomes and the number of favorable outcomes.

There are 4 pairs of sandals, 5 pairs of tennis shoes, and 3 pairs of boots in the closet. Assuming Kyra selects a pair of sandals first, she has 4 options. After Kyra selects the sandals, there will be 3 pairs of sandals left.

Since the sandals are chosen without replacement, her sister will have 5 options for the pair of tennis shoes. The total number of possible outcomes is the product of the options for each step: 4 * 5 = 20.

Therefore, the probability that Kyra selects a pair of sandals and her sister selects a pair of tennis shoes is 3/20.

Answer:

The range for the equation is all real numbers.

Step-by-step explanation:

The range of an equation is the set of y-values that you can get by plugging in all possible x-values.

Another way to put it is, when you graph the equation, whatever y-values the line produces, is its range.

Graphing y=2x-3, you can see it is a graph with a positive slope that extends from negative infinity y-value to positive infinity x-value.

For the given values, the quadratic function is a vertical parabola open downward (vertex is a maximum)

The equation in vertex form is equal to

[tex]f(x)=a(x-h)^{2} +k[/tex]

where

(h,k) is the vertex

a is a coefficient

we have

Step-by-step explanation: The converse of a conditional is when the two statements switch spots, for example:

Conditional: If someone like ice cream, they have brown hair

Converse: If someone has brown hair, they like ice cream

The converse of our given conditional would be:

If two lines do not intersect, they are parallel

This eliminates Option D

Next, the converse is false.

Skew lines (example attached) do not intersect and are also not parallel, meaning if two lines do not intersect, they could be either parallel or skew.

This eliminates Option C and B, leaving us with Option A

We want to find the converse statement to one given statement and see if it is true.

We will see that the correct option is a:

If two lines do not intersect, they are parallel. One statement is false. If two lines do not intersect, they could be skew.

A general statement is written as:

If P then Q.

Where P and Q are two given propositions.

The converse statement to the above shown is:

If Q then P.

For this question, we have the statement:

If two line are parallel, they do not intersect.

Then we can write the converse statement as:

If two lines do not intersect, they are parallel.

Which is false, in 3-dimensions we can have two non-parallel lines that don't intersect each other (parallel lines must not intersect and also live on the same plane).

Then the correct option is the first one:

a: If two lines do not intersect, they are parallel. One statement is false. If two lines do not intersect, they could be skew.

x = 134.60

Step-by-step explanation:

The trip to the dentist had a flat fee plus 4 cavities for a total cost of 628.35

fee + 4 * cost of cavity = 628.35

Let x = the cost of each cavity

89.95 + 4x =628.35

Subtract 89.95 from each side

89.95-89.95 + 4x =628.35-89.95

4x =538.40

Divide each side by 4

4x/4 =538.40/4

x =134.60

B^2 for B = 9 means squaring the value of 9, resulting in 9^2, which equals 81. Therefore, B^2 for B = 9 is 81.

To evaluate B^2 for B = 9, you simply substitute the value of B into the expression and then perform the calculation. Here's how it's done:

B^2 means "B squared," which is equivalent to multiplying B by itself. So, for B = 9, we have:

[tex]\(B^2 = 9^2 = 9 \times 9\)[/tex]

Now, calculate the product:

[tex]\(9 \times 9 = 81\)[/tex]

So, B^2 for B = 9 is equal to 81.

In summary, when you substitute B = 9 into the expression B^2, you get 9^2, which equals 81. Therefore, B^2 for B = 9 is 81.
