Answer:

Matt  had 12 cookies his 2 other friends came over and divided them equally with them now each of them had four.

Step-by-step explanation:

The real world problem that could represent the bar diagram is,

'' Jean have $12 in his bank account. If he spend 2/3rd part of balance account, then what he had now?''

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

A bar diagram is shown in figure.

Now, We can make a real world problem that could represent the bar diagram.

So, We get;

'' Jean have $12 in his bank account. If he spend 2/3rd part of balance account, then what he had now?''

Clearly, Above question represent the the bar diagram shown.

Step-by-step explanation:

To draw the graph, follow these steps:

The three inequalities given form a triangle.

The first equation, y ≤ 2x + 5, has a y-intercept at (0, 5) and a point at (-2, 1).

The second equation, y < -3x + 10, has points at (3, 1) and (2, 4).

Use two points to draw the lines.

After the lines are drawn, determine which side of the line the inequality works on. You can do this by testing points that are not on the line.

I will test each inequality using (0, 1):

y ≤ 2x + 5

0 ≤ 2 + 5

This is correct, so the inequality for y ≤ 2x + 5 will be shaded towards (0, 1).

y < -3x + 10

0 < -3 + 10

This is correct, so the inequality for y < -3x + 10 will be shaded towards (0, 1).

0 ≤ 1

This is correct, so the inequality for 0 ≤ y will be shaded upwards towards (0, 1).

The end result of this graph is all three inequalities being shaded (inwards).

The solution is a triangle with points at (1, 7), (3.33333, 0), and (-2.5, 0).

Answer:

104 Inches

Step-by-step explanation:

Alyssa's blanket contains 7 pink stripes and 6 white  stripes.

Total Number of Stripes =7+6=13

Since each stripe is 8 inches wide.

The width of Alyssa's blanket will be the product of the number of stripes by the width of each stripe.

Therefore:

Width = 13 X 8 Inches =104 Inches

Alyssa's blanket is 104 Inches wide.

Answer:

(y²- 2y + 3) will be the answer.

Step-by-step explanation:

The given expression is (y³ - y² + y + 3) ÷ (y + 1)

By using long division method,

y + 1) y³ - y² + y + 3 (y²- 2y + 3

        y³ + y²

            - 2y² + y

            -2y² - 2y

                      3y + 3

                      3y + 3

                             0

Here the quotient is (y² - 2y + 3) and the remainder is 0.

Therefore, answer will be (y² - 2y + 3).

Answer:

sandwich = 6.50

Step-by-step explanation:

Let s = sandwich price

d = drink price

6s + 4d = 53

4s + 6d = 47

Multiply the first equation by 3

18s + 12d = 159

Multiply the second equation by -2

-4s - 12d = -94

Add these equations together

18s + 12d = 159

-8s - 12d = -94

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

10s = 65

Divide by 10

s = 65/10

s =6.5

Answer:

Two solutions were found :

x =(6-√40)/2=3-√ 10 = -0.162

x =(6+√40)/2=3+√ 10 = 6.162

Step-by-step explanation:

Trying to factor by splitting the middle term

1.1     Factoring  x2-6x-1

The first term is,  x2  its coefficient is  1 .

The middle term is,  -6x  its coefficient is  -6 .

The last term, "the constant", is  -1

Step-1 : Multiply the coefficient of the first term by the constant   1 • -1 = -1

Step-2 : Find two factors of  -1  whose sum equals the coefficient of the middle term, which is   -6 .

     -1    +    1    =    0

The solutions to the equation x² + 6x + 1 = 0 are -0.177 and -5.823.

Given:

quadratic equation x² + 6x + 1 = 0

The quadratic formula states that for an equation of the form ax² + bx + c = 0, the solutions for x can be found using the following formula:

[tex]x = \dfrac{-b \pm \sqrt {(b^2 - 4ac)}}{2a}[/tex]

In our equation, a = 1, b = 6, and c = 1.

Now, let's plug these values into the quadratic formula:

[tex]x = \dfrac{-6 \pm \sqrt {(6^2 - 4(1)(1))}}{2(1)}[/tex]

x = (-6 ± √(36 - 4)) / 2

x = (-6 ± √32) / 2

Now, the two solutions for x:

1. x = (-6 + √32) / 2

      = (-6 + 5.66) / 2

      = -0.177

2. x = (-6 - √32) / 2

      = (-6 - 5.66) / 2

       -5.823

So, the solutions are -0.177 and -5.823.

Answer: The slope is 4 and the y-intercept is 12.

Step-by-step explanation:

(-3,0)  and (-2,4)

find the difference in the Y values  0-4=-4

find the difference in the v- values   -3-(-2) =-1

Divide the y difference by the x difference   -4/-1 = 4 so 4 is the slope

Now to find the y intercept, use the formula y=mx + b and plot in coordinates and slope to find the y- intercept

4= 4(-2) + b

4 = -8 + b

+8    +8

b= 12  so the y intercept is 12

now the equation will be like y = 4x + 12

(-3,0)  and (-2,4)

find the difference in the Y values  0-4=-4

find the difference in the v- values   -3-(-2) =-1

Divide the y difference by the x difference   -4/-1 = 4 so 4 is the slope

Now to find the y intercept, use the formula y=mx + b and plot in coordinates and slope to find the y- intercept

4= 4(-2) + b

4 = -8 + b

+8    +8

b= 12  so the y intercept is 12

now the equation will be like y = 4x + 12

You must factor the numerator and denominator and cancel the common factors.
