Answer:

8 ounces for each pot

Step-by-step explanation:

First, we know there are 16 oz in a pound. Since there are 4 pounds, we multiply 4 by 16 to get 64, which is the amount of oz of dirt Franklin will plant. We then divide 64 by 8, to find out the amount of oz per pot.

The values of a and b using the factor theorem for the polynomial f(x), we set f(1) and f(-1) equal to zero. Solving the resulting system of equations, we find that a = 12 and b = -1.

To find the values of a and b using the factor theorem, we need to use the given factors (x - 1) and (x + 1) and the fact that they are roots of the polynomial f(x).
The factor theorem states that if (x - c) is a factor of a polynomial, then f(c) = 0. Therefore, we can set x = 1 and x = -1 in the polynomial f(x) to get two equations.
First, let's substitute x = 1 into f(x):
f(1) = (1)^3 + a(1)^2 + b(1) - 12
f(1) = 1 + a + b - 12
Next, let's substitute x = -1 into f(x):
f(-1) = (-1)^3 + a(-1)^2 + b(-1) - 12
f(-1) = -1 + a - b - 12
Since (x - 1) and (x + 1) are factors, f(1) and f(-1) must equal zero. Therefore, we can set the two equations equal to zero and solve for a and b:
1 + a + b - 12 = 0
-1 + a - b - 12 = 0
Rearraning the equations, we have:
a + b = 11
a - b = 13
Now, we can solve this system of equations. Adding the two equations, we get:
2a = 24
a = 12
Substituting the value of a into one of the equations, we find:
12 - b = 13
b = -1
Therefore, the values of a and b are 12 and -1 respectively.

Answer:

1/3

Step-by-step explanation:

Answer:

1/2 % 1/3 = 3/2 or 1 1/2 cups of 1/3 are equal to 1/2 cup. Therefore, one and a half 1/3 cups are equal to 1/2 cups.

Step-by-step explanation:

The solution to the inequality is x < -5.

To solve the inequality -2(5x + 1) > 48, we need to isolate the variable x. Let's simplify the equation step by step:

-2(5x + 1) > 48

Start by distributing -2 to the terms inside the parentheses:

-10x - 2 > 48

Next, isolate the variable by adding 2 to both sides of the inequality:

-10x - 2 + 2 > 48 + 2

-10x > 50

Now, divide both sides by -10, remembering to flip the direction of the inequality when dividing by a negative number:

(-10x) / (-10) < 50 / (-10)

x < -5

This means that any value of x that is less than -5 will satisfy the original inequality. To express the solution using an inequality symbol, we write x ∈ (-∞, -5). The symbol (-∞, -5) represents the interval of all real numbers less than -5, including -5 itself.

Answer:

Step-by-step explanation:

Two angles are called supplementary when their measures add up to 180 degrees.

so

180 - 27 = 153°

Answer:

X = 109

Step-by-step explanation:

I = 5 – 2 (180) = 540  

100 + 102 + 108 + 121 = 431

540 – 431 = 109

X= 109

The value of the angle x will be 109 degrees.

A polygon is a closed polygonal chain made up of a finite number of straight-line segments that are joined to form a planar figure in a geometry or polygonal circuit. A polygon is a region that is bounded by a bounding circuit, a bounding plane, or both.

Given that an irregular pentagon with five different measured angles and five unequal sides. The angles of the pentagon are x degrees, 121 degrees, 108 degrees, 102 degrees, and 100 degrees.

The value of the angle x will be calculated as below:-

100 + 102 + 108 + 121 + x = 540

x = 540 – 431

x= 109

Therefore, the value of the angle x will be 109 degrees.

Answer: 2.5=Y

Step-by-step explanation: you divide -2 by 5 which is -2.5 then you add 5 giving you the result of 2.5 or Y

Answer:

See attached image

Step-by-step explanation:

In order to graph, find about three different points that belong to the line, and join them with a straight line.

The points I suggest are using easy values of "x" that will make the calculation of the y-value simple. For example the x-values: 0, 5, -5

When x = 0 , y becomes: y = -(2/5) (0) + 5 = 5

When x = 5,  y becomes : y = -(2/5) (5) + 5 = - 2 + 5 = 3

When x = -5,  y becomes: y = -(2/5) (-5) + 5 = 2 + 5 = 7

Then plot the points (0, 5), (5, 3) and (-5, 7) on the plane, and join them with a line as shown in the attached image.

3. The quotient of two times a number and -11: -2x / 11

4. The sum of the square root of two times a number and 11: [tex]\sqrt{(2x) + 11}[/tex]

The pairings between the mathematical descriptions and their corresponding algebraic expressions:

1. The absolute value of twice a number increased by 11: |2x + 11|

  This expression represents the absolute value of the sum of twice a number (2x) and 11. The vertical bars indicate the absolute value operation, which ensures that the result is always positive or zero.

2. The square root of the difference of the square of a number and 11: [tex]\sqrt{(x^2 - 11)}[/tex]

  This expression represents the square root of the difference between the square of a number ([tex]x^2[/tex]) and 11. The square root function (√) returns the positive square root of the expression within the parentheses.

3. The quotient of two times a number and -11: -2x / 11

  This expression represents the division of -2x (twice a number multiplied by -1) by 11. Dividing by 11 results in a quotient that may be positive, negative, or zero.

4. The sum of the square root of two times a number and 11[tex]\sqrt{(2x) + 11}[/tex]

  This expression represents the sum of the square root of twice a number [tex]\sqrt{((2x))}[/tex] and 11. The square root function (√) calculates the positive square root of 2x, and then 11 is added to the result.

a. The final result is -45 + ?(-3).

b. We have a negative value inside the square root, this expression is not defined in the real number system. If you're working with complex numbers, we can proceed by evaluating the square root of -130.

c. The result is 10.

d. The result is 6.

a. -15 × (-3 + 5) - 15 + ?(-3)

Let's simplify the expression step by step:

-15 × (-3 + 5) - 15 + ?(-3)

First, we can simplify the expression within the parentheses:

-15 × 2 - 15 + ?(-3)

Next, we perform the multiplication and addition:

-30 - 15 + ?(-3)

Now, let's address the "?(-3)" part. Since we don't have a specific value for the missing factor, we'll leave it as it is for now.

-30 - 15 + ?(-3)

Finally, we can simplify the expression by performing the subtraction:

-45 + ?(-3)

The final result is -45 + ?(-3).

b. √(-125 - 5) × 3²

Let's simplify this expression step by step:

√(-125 - 5) × 3²

First, we evaluate the expression within the square root:

√(-130) × 3²

Since we have a negative value inside the square root, this expression is not defined in the real number system. If you're working with complex numbers, we can proceed by evaluating the square root of -130.

c. (-5) - (-8) - (-7)

Let's simplify this expression step by step:

(-5) - (-8) - (-7)

To simplify double negatives, we can rewrite the expression as addition:

(-5) + 8 + 7

Now, we can perform the addition:

-5 + 8 + 7 = 3 + 7 = 10

The result is 10.

d. (-5) - (-8) - (-7) - (+2) - (+2)

Let's simplify this expression step by step:

(-5) - (-8) - (-7) - (+2) - (+2)

Again, let's rewrite the double negatives as addition:

(-5) + 8 + 7 - 2 - 2

Now, we can perform the addition and subtraction:

-5 + 8 + 7 - 2 - 2 = 3 + 7 - 2 - 2 = 10 - 4 = 6

Answer:

Step-by-step explanation:

Answer:  The slope is 2/3

Step-by-step explanation:

The difference in the rise (y-values) 2,  divided by the difference in the run (x-values) 3,  is 2/3.

You can see this by looking at the places where the graphed line crosses the grid, and counting the squares in each direction between those points, or you can use the formula (y - y₁) ÷ (x - x₁)  

Using the values of coordinates (3,1) and (0, -1)

1 -(-1) ÷ 3 - 0

2 ÷ 3

2/3

The slope of the given line is 2/3.

From the given figure, the coordinates of the points on line are (3, 1) and (-3, -3).

The slope of a line is defined as the change in y-coordinate with respect to the change in x-coordinate of that line.

The slope of a line is m=(y2-y1)/(x2-x1)

Using the coordinates (x1, y1) = (3, 1) and (x2, (y2) = (-3, -3)

Slope(m) = (-3-1)/(-3-3)

= -4/(-6)

= 2/3

Therefore, the slope of the given line is 2/3.
