From the situation described, we have that:

a. The absolute value equation is: |w - 35| = 8.

b. The solutions are w = 27 and w = 43, meaning that the minimum weight is of 27 pounds and the maximum weight is of 43 pounds.

A home improvement store sells bags of sand, which are labeled as weighing 35 pounds. The equipment used to package the sand produces bags with a weight that is within 8 pounds of the labeled weight.

The absolute function is defined by:

It measures the distance of a point x to the origin, hence, for example, |-2| = |2| = 0.

For this problem, the difference between the weight w and 35 pounds is of 8 pounds, hence the equation is:

|w - 35| = 8.

From the definition, the solutions are given as follows:

The solutions are w = 27 and w = 43, meaning that the minimum weight is of 27 pounds and the maximum weight is of 43 pounds.

The equation of line is y = -4

Given the points:

(x₁, y₁) = (-1, -4)

(x₂, y₂) = ( 3, -4)

The slope-intercept form:

y = mx + b

Where, m is the slope and b is the y-intercept, that is (0, b)

The formula for slope:

m = (y₂ – y₁) / (x₂ – x₁)

We have given

x₁ = -1

x₂ = 3

y₁ = -4

y₂ = -4

So,

m = (-4 – (-4)) / (3 – (-1)) = (-4 + 4) / (3 + 1) = 0/4 = 0

Therefore we have the equation of the line as:

y = mx + b

-4 = 0(x) + b

-4 = 0 + b

b = -4

Therefore, the equation of line y = -4

Applying the distance formula, the value of a is 2 or -2.

The distance formula is:

d = [tex]\sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}[/tex].

Given the following:

d = XY = 10 units

X(a - 5, -2a) = (x1, y1)

Y(a + 1, 2a) = (x2, y2)

Plug in the values into the distance formula

10 = √[((a + 1) - (a - 5))² + (2a - (-2a))²]

10 = √[(a + 1 - a + 5)² + (2a + 2a)²]

10 = √(6² + (4a)²)

10 = √(36 + 16a²)

10² = 36 + 16a²

100 = 36 + 16a²

0 = -100 + 36 + 16a²

0 = 16a² - 64

16a² - 64 = 0

Factorize

16(a² - 4) = 0

16(a - 2)(a + 2) = 0

a = 2 or a = -2

Therefore, applying the distance formula, the value of a is 2 or -2.

Answer:

2 times as much

Step-by-step explanation:

1 hour 2/3 = 60 + (2/3) 40 mins = 100 minutes

3 hours 1/3 = (60 ×3 ) + 20 mins = 200 mins

200 is twice as much as 100

The number of windows which can be framed with three 10-foot long pieces of lumber given the dimensions of the windows is; two and a half.

It follows from the task content that the number of windows that can be made given the dimensions of the windows be determined.

On this note, it follows that since the windows are 3 feet high and 3 feet width, the perimeter of each window(square shaped) covered by lumber is;

P = 4s

P = 4 × 3

P = 12 feet.

Hence, each window requires 12 feet of lumber.

However, since the builder has only three 10-foot long pieces of lumber which is equivalent to; 3 × 10 = 30 feet worth.

The number of windows that can be made is;

= 30/12

= 2.5.

Ultimately, only 2 and a half windows can be framed from the three 10-foot long pieces of lumber.

Answer:

x=8

Step-by-step explanation:

starts with 0.5x+2=6, so move the constant to the right, 0.5x=6-2, then calculate the right side, 0.5x=4, then divide both sides, and x=8

Answer:

x = 8

Step-by-step explanation:

Get variable on left and constants on right

0.5x = 6 - 2

0.5x = 4

Divide both sides by 0.5

x = 8

According to the given function, we can throw it to the height of 6.6 m.  So, yes we can throw it high enough to reach the ledge.

The given equation is quadratic. A quadratic equation is defined as an equation of a single variable with the highest power of 2. In general, the quadratic equation can be expressed as h(x)= [tex]ax^2- bx + c[/tex], where a, b and c are arbitrary constants. The solution for a quadratic equation is given by:

The function rule for h(x) = -3x -3.

In mathematics, functions can be manipulated algebraically to obtain graphs of functions through certain transformations. Such transformations are reflections of the x-axis or the y-axis. To flip a function f(x) on the x-axis, multiply the whole function by a negative value to get -f(x), and to flip a function f(x) on the y axis, f(-x ), specify the x variable with a negative value. If it is reflected around the y-axis, it will stay the same, which gives h(x) = 3x + 3. Flipping around the x-axis (assuming y = 0) has the y-axis as the axis of symmetry, but it is concave down.

The function rule around the x-axis gives a complementary sign of the value of the function, so

h(x) =-3x-3 will be reflection of f(x) =3x+3

The statement which describes the effect of replacing the graph of f(x) with the graph of f(x) - 5 is : (b) the graph shifts 5 units down.

What is Transformation?

Transformation :- The transformations of functions define how to graph a function is moving and how its shape is being changed. There are basically three types of function transformations: translation, dilation, and reflection.

f(x) = f(x) + k

This is a translation transformation that shifts the original function f(x) either k units up or k units down. If k is more than 0 then k shifts up. If k is less than 0 then k shifts down.

Here, k = -5<0

Hence, the shift is 5 units down.

The absolute inequality will be x ≥ | 8.9 ± 0.15 |mm and the compound inequality will be x > 8.75, x< 9.05.

Inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.

Given that the length is 8.9 mm with a tolerance of 0.15mm.

The absolute inequality will be written as below:-

x ≥ | 8.9 ± 0.15 |mm

The compound inequality will be written as:-

x  > 8.75,

x < 9.05.

Therefore, the absolute inequality will be x ≥ | 8.9 ± 0.15 |mm and the compound inequality will be x > 8.75, x< 9.05.

The number of apples in the 12th bag is 9.

There are 12 bags of apples on the market stalls.

The mean number of apples in each bag is 8.

Therefore, the number of apples in the 12th bag can be calculated as follows:

mean = ∑fx / ∑f

Hence,

let the number of apples in the 12th bag = a

mean = 6 × 1 + 7 × 4 + 8 × 2 + 9 × 3 + 10 × 1 + x × 1/ 1 + 4 + 2 + 3 + 1 + 1

mean = 6 + 28 + 16 + 27 + 10 + x / 12

mean = 87 + x / 12

8 = 87 + x / 12

cross multiply

96 = 87 + x

x = 96 - 87

x = 9
