Write the equation of the line that passes through (3, 4) and (2, –1) in slope-intercept form.

Answer:

x=1

Step-by-step explanation:

Question says to use a graphing calculator or online application to find the solution to [tex]3-x = x^3 + x[/tex] to the nearest tenth.

So we will create two equations y = 3-x and [tex]y = x^3 + x[/tex] using each sides of the given equation.

Now we graph both equation using some online calculator or graphing calculator. I'm going to use Desmos calculator.

Intersection point of both graphs will give the solution.

From graph we see that intersection point is at (1,2).

We are looking for value of x only.

Hence final answer is x=1

Step-by-step explanation:

Final answer:

The price of an item can increase due to inflation, a reduction in supply, or an increased demand. High inflation rates make it challenging to determine the exact causes of price increases and complicate decision-making for both consumers and businesses.

Explanation:

The price of an item can increase due to various factors such as inflation, a decrease in the supply of the good, or an increase in the demand for the good. In situations of high inflation, such as the case in Israel in 1985 with an annual inflation rate of 500%, prices can change so frequently that stores might not post prices directly on items. This makes it challenging for consumers and businesses to respond to economic signals, complicates price comparisons, and makes it difficult to deduce the cause of price increases.

Inflation implies a general increase in prices and can affect all goods and services, leading consumers to spend money quickly before prices rise further. A decrease in supply, perhaps due to production issues or scarcity of resources, can lead to higher prices if demand remains constant. Conversely, an increase in demand for a good without a corresponding increase in supply can also drive prices up. Recognizing the reasons behind rising prices can be complex, especially when high inflation rates obscure the underlying economic indicators.

The question is about finding the length of a rectangle. By creating and solving a quadratic equation with provided information, the width and length of the rectangle are 4 cm and 6 cm respectively.

The problem involves finding the length of a rectangle. To solve this, we need to consider the fact that we know information about the dimensions and area of the rectangle. The area of a rectangle is obtained by performing the multiplication of the length and the width. In this specific problem, it's stated that the length is 2 cm more than the width, and we also know that the area of the rectangle is 24 cm2.

Let's represent the width by x. Therefore, the length would be x+2. Since the area is the length multiplied by the width, we create the equation x*(x+2) = 24, which simplifies to x2+2x=24. Subtracting 24 from both sides, we get x2+2x-24 = 0.

This a quadratic equation and we'll solve for x using the quadratic formula, which results in x = 4 or x = -6. Since the width cannot be negative, x = 4 cm. After this, substitute the width (x) into the length equation. The length (x + 2) is 4 cm + 2 cm = 6 cm.

The length of the rectangle is [tex]\( 2\sqrt{7} \)[/tex]cm.

To solve this problem, let's denote the width of the rectangle as [tex]\( w \)[/tex] cm. According to the information given, the length of the rectangle is then [tex]\( w + 2 \)[/tex] cm. The area of a rectangle is given by the product of its length and width, so we can set up the following equation:

[tex]\[ w \times (w + 2) = 24 \][/tex]

Expanding the equation, we get:

[tex]\[ w^2 + 2w = 24 \][/tex]

To solve for [tex]\( w \)[/tex], we need to rearrange the equation into standard quadratic form:

[tex]\[ w^2 + 2w - 24 = 0 \][/tex]

Now, we can factor this quadratic equation:

[tex]\[ (w + 6)(w - 4) = 0 \][/tex]

Setting each factor equal to zero gives us two possible solutions for [tex]\( w \)[/tex]:

[tex]\[ w + 6 = 0 \quad \text{or} \quad w - 4 = 0 \] \[ w = -6 \quad \text{or} \quad w = 4 \][/tex]

Since the width of a rectangle cannot be negative, we discard[tex]\( w = -6 \)[/tex] and accept [tex]\( w = 4 \)[/tex] cm as the width of the rectangle.

Now that we have the width, we can find the length by adding 2 cm to the width:

[tex]\[ \text{Length} = w + 2 = 4 + 2 = 6 \text{ cm} \][/tex]

However, we need to check if this length satisfies the area condition:

[tex]\[ \text{Area} = w \times \text{Length} = 4 \text{ cm} \times 6 \text{ cm} = 24 \text{ cm}^2 \][/tex]

This confirms that the length is indeed 6 cm when the width is 4 cm. Therefore, the length of the rectangle is [tex]\( 2\sqrt{7} \)[/tex] cm, since [tex]\( 6 = 2\sqrt{7} \)[/tex] when rounded to the nearest whole number.

Answer: popcorn = $5.75 per bag

Step-by-step explanation:  

Set up the equation for each person.

Let x represent the cost of one drink and y represent the cost of one bag of popcorn.

           drinks    popcorn       Cost                     EQUATION

Naomi:      9            8            $111.25                9x + 8y = 111.25

Sofia:         3            2           $33.25                 3x + 2y = 33.25

Next, solve the system:

9x + 8y = 111.25   →    1(9x + 8y = 111.25)   →    9x + 8y = 111.25

3x + 2y = 33.25   →  -3(3x + 2y = 33.25)   → -9x  - 6y = -99.75

                                                                                2y =  11.50

                                                                                  y =  5.75

Answer:

System of equations :

$111.25=$9x+$8y

$33.25=$3x+$2y

The cost of 1 drink = $x = $7.25

The cost of 1 popcorn bag = $y = $5.75

Step-by-step explanation:

Given :  

Naomi spends a total of $111.25 on 9 drinks and 8 bags of popcorn.

Sofia spends a total of $33.25 on 3 drinks and 2 bags of popcorn.

To Find : A system of equations that can be used to find the price of one drink and the price of one bag of popcorn.

Solution :

Let cost of 1 drink = $x

⇒ cost of 9 drinks = $9x

⇒ cost of 3 drinks = $3x

Let cost of 1 popcorn bag = $y

⇒Cost of 8 popcorn bags = $8y

⇒Cost of 2 popcorn bags = $2y

Since Naomi spends a total of $111.25 on 9 drinks and 8 bags of popcorn.

So, equation will be : $111.25=$9x+$8y  --(A)

Since, Sofia spends a total of $33.25 on 3 drinks and 2 bags of popcorn.

So, equation will be :  $33.25=$3x+$2y--(B)

SOLVING A and B by using substitution method

finding value of x from equation B :

[tex]x=\frac{33.25-2y}{3}[/tex]

Putting this value in Equation (A)

⇒[tex]111.25=9(\frac{33.25-2y}{3})+8y[/tex]

⇒[tex]111.25=99.75-6y+8y[/tex]

⇒[tex]111.25=99.75+2y[/tex]

⇒[tex]y = 5.75[/tex]

Thus, cost of 1 popcorn bag =y = $5.75

Now put this value of y in equation A to get value of x

⇒$111.25=$9x+$8(5.75)

⇒$111.25-$46 = 9x

⇒$65.25 = 9x

⇒65.25/9 = x

⇒$7.25 = x

Thus, The cost of 1 drink = $x = $7.25

Answer:

The 14th term is -58

Step-by-step explanation:

The formula for an arithmetic sequence is

an = a1+d(n-1)

where a1 is the first term

d is the common difference and

n is the term number

a1 = 7

d = 2-7 = -5

Check -3-2 = -5   so d = -5

an = 7 -5(n-1)

We want the 14th term

a14 = 7 -5(14-1)

a14 = 7 -5(13)

a14 = 7 -65

a14 = -58

Answers:

i) It can graze an area of approximately 961.625 square meters

ii) The ungrazed area is roughly 802.375 square meters

note: I used pi = 3.14 which is approximate; if you want more accuracy, use more decimal digits in pi

===============================================

Explanation:

Check out the attached image below for a visual diagram.

The area of a circle is the formula

A = pi*r^2

Use r = 35 as the radius and pi = 3.14 as the approximation for pi, to get,

A = pi*r^2

A = 3.14*35^2

A = 3846.5

Then divide this by 4 to get the area of a quarter circle

A/4 = 3846.5/4 = 961.625

This is the approximate area the horse can graze

------------

Subtract this from 42^2 = 42*42 = 1764 because this is the area of the entire square. Doing this will get you the ungrazed area

Ungrazed area = (entire plot) - (grazed area)

Ungrazed area = (entire area of square) - (area of quarter circle)

Ungrazed area = 1764 - 961.625

Ungrazed area = 802.375

Answer:

red  2/3

blue 1/2

The lines do not have the same slope so they are  not parallel

Step-by-step explanation:

We can find the slope of the red line by using the formula

m = (y2-y1)/(x2-x1)

We have the points (0,2) and (3,4)

m= (4-2)/ (3-0)

  = 2/3

We can find the slope of the blue line by using the formula

m = (y2-y1)/(x2-x1)

We have the points (0,-2) and (4,0)

m= (0--2)/ (4-0)

  = (0+2)/(4-0)

  = 2/4

 =1/2

The lines  do not have the same slope so they are  not parallel
