The attached graph is defined by f(x) = x² + 5|x| + 6.

What is the graph function?

The graph of a function f is the set of all points in the plane of the form (x, f(x)). We could also define the graph of f to be the graph of the equation y = f(x). So, the graph of a function is a special case of the graph of an equation.

We have,

y = x² + 5|x| + 6

we know,

|x|² = x² use this ,

y = |x|² + 5|x| + 6

Steps for drawing y = |x|² + 5|x| + 6

step1 :- first draw y = x² + 5x + 6, this graph is quadratic equation .

step2:- Leave the part of y=x² + 5x + 6 right side to the y-axis and also take its image with respect to the y-axis as a plane mirror.

step3 :- now remove the part of y = x² + 5x + 6 to left side from y - axis .

now your graph is ready

you can see in the figure attached.

Hence, the attached graph is defined by f(x) = x² + 5|x| + 6.

Answer:

How many ways can they fill the 4 positions?

The Answer is B. 210

Answer: b. 210

Step-by-step explanation:

Answer:  

A) 15

B) Summer Swim

Step-by-step explanation:

How to solve problem "A":

45+3.50x =6.50x

Take 3.50 from each side.

6.50-3.50=3

45=3x

Now you divide 45 divided by 3.

45/3=15

So after 15 visits, you'll be charged the same amount.

6.50 (15)=97.5

3.50 (15)+45= 97.5

So it's definitely correct.

_________________________________________________________

How to solve problem "B":

All we have to do is plug 32 into "x"

Equation 1: 45+3.50(32)= 157

Equation 2: 6.50 (32)=208

So equation 1 definitely is cheaper. So it's the Summer Swim that's cheaper

Average velocity of the car as calculated from the given data is 6m/s.

The average velocity is calculated by dividing the total distance travelled by the whole time that has passed. Given the velocity as a function of time, you may integrate the velocity function from t = 4 to t = 8 to determine the total distance travelled.

The opposite of taking a derivative is to integrate; in other words, the function I get when I take a derivative is 2t1/2 + 1. Assuming you are aware of how to do that If not, you can input the aforementioned integral into your TI-84 to obtain the result.

The integral turns out to be

(4/3)t^3/2 + 4t so x(t)

= (4/3)t3/2 + 4t and x(8) - x(4)

= (4/3)(8)3/2 + 4(8) - [(4/3)(4)3/2 + 4(4)]

= 24 meters

The distance travelled in total was 24 meter and it took 4 seconds (8-4) to do it, so the average velocity is 24 /4 = 6 m/s.

You see from the graph that when x = 0, y = 2 so the y-intercept is ( 0 , 2).

you are given points (-6 , 3) and (6 , 1). Find slope:

slope = change in y / change in x

slope = (3 - 1) / (-6 - 6)

slope = 2/-12

slope = -1/6

slope-intercept form: y = mx + b where m = slope and b = y intercept.

Answer:

y = 2x - 2

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

calculate m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (0, - 2) and (x₂, y₂ ) = (1, 0) ← 2 points on the line

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

the line crosses the y- axis at (0, - 2 ) ⇒ c = - 2

y = 2x - 2 ← equation of line

Answer:

y = 2x - 2

Step-by-step explanation:

The equation y = mx + b is a standard form of a linear equation in one variable. It represents a straight line on a graph

In this equation, y is the dependent variable, which is the variable that is being measured or predicted. The independent variable is x, which is the input or cause in the relationship.

The coefficient m is the slope of the line, which tells you the rate of change between the two variables. It represents how much the value of y changes for each unit change in the value of x. A positive slope means that the line goes up as you move from left to right, while a negative slope means that the line goes down.

- Our slope is positive

- slope (m) = rise / run = 2/1 = 2

The constant b is the y-intercept, which is the point where the line crosses the y-axis. It represents the value of y when x is equal to 0.

- Our y-intercept is -2

m is 2 and b is -2, the equation y = 2x - 2 represents a line with a slope of 2 and a y-intercept of -2. This means that for every 1 unit increase in the value of x, the value of y increases by 2 units, and the line crosses the y-axis at the point (0, -2).

Answer:

Answer = 88 ft²

Step-by-step explanation:

Step 1: Divide the composite shape into two separate parrellagrams

    1. Dimensions of shape 1: Length is 10 ft, and width is 4 ft

    2. Dimensions of shape 2: Length is 8 ft, and width is 6 ft

Step 2: Multiply the length by the height of each shape

    Area = lw

    3. Area of shape 1: 10 ft ∙ 4 ft = 40 ft²

    4. Area of shape 2: 8 ft ∙ 6 ft = 48 ft²

Step 3: Add both areas together to get the total area of the composite shape

    5. 40 ft² + 48 ft² = 88 ft²

    Hence, the total area of this composite figure is 88 ft²

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Number of puppies = 7

Number of adult dogs = 4

This can be written as,

7 puppies = 4 adult dogs

Multiply 6 on both sides.

42 puppies = 24 adult dogs

The required quotient is x² + x + 1 + (2/ x -1) which is determined by the synthetic division.

A quotient is defined as the outcome of dividing an integer by any divisor that can be said to be a quotient.

Use the divisor and find x :

x - 1 = 0  add 1

x= 1

Now we'll divide with the number one:

Take the coefficients from the terms in front of them.

Make careful to include 0's for x² and x since all terms must be included.

set it up with a 1 in a box:

1|  1   0   0  1   bring the first number down

____________

    1                    multiply the boxed number by the first number and add it                                 to the second number

1|  1   0   0  1  

____+1_____       repeat with the rest of the terms

When you're finished, use the new numbers to build an equation that begins with a term that has one fewer degree than the previous equation.

Because there is a remnant, divide it by the original divisor.

Answer:

(A) ∠Y ≅ ∠C.

Step-by-step explanation:

To prove that two triangles are congruent by ASA (Angle-Side-Angle), you need to show that two angles in one triangle are congruent to two corresponding angles in the other triangle, and that the side between the two angles is congruent to the corresponding side in the other triangle.

Given that ∠X ≅ ∠D and ∠DE ≅ ∠XW, the third congruence needed to prove that ΔXWY ≅ ΔDEC by ASA is:

(A) ∠Y ≅ ∠C

This is because ∠Y and ∠C are the corresponding angles in the two triangles that have not been shown to be congruent.

So the answer is (A) ∠Y ≅ ∠C.
