The solution to the equation is x = 38

Expressions are mathematical statements that are represented by variables, coefficients and operators

The equation is given as

1/3|x - 8| = 10

Multiply through by 3

So, we have

|x - 8| = 30

Remove the absolute bracket

So, we have

x - 8 = 30

Add 8 to both sides of the equation

So, we have

x = 38

Hence, the solution to the equation is x = 38

Answer:

AB and CD are congruent.

Step-by-step explanation:

Given points:

To determine if AB and CD are congruent, calculate the length of the two lines using the distance formula.

[tex]\boxed{\begin{minipage}{7.8 cm}\underline{Distance Formula}\\\\$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$\\\\where $(x_1,y_1)$ and $(x_2,y_2)$ are the two endpoints.\end{minipage}}[/tex]

[tex]\begin{aligned}\implies AB & = \sqrt{(x_B-x_A)^2+(y_B-y_A)^2}\\& = \sqrt{(2-4)^2+(6-1)^2}\\& = \sqrt{(-2)^2+(5)^2}\\& = \sqrt{4+25}\\& = \sqrt{29}\end{aligned}[/tex]

[tex]\begin{aligned}\implies CD & = \sqrt{(x_D-x_C)^2+(y_D-y_C)^2}\\& = \sqrt{(-4-(-2))^2+(-3-2)^2\\& = \sqrt{(-2)^2+(-5)^2}\\& = \sqrt{4+25}\\& = \sqrt{29}\end{aligned}[/tex]

Therefore, as AB = CD, we can conclude that AB and CD are congruent.

The graph of the quadratic equation is shown in the image attached below.

In accordance with algebra fundamental theorem, we can construct a quadratic equation by knowing the locations of at least three points on Cartesian plane. Herein we find a quadratic equation in vertex form, whose formula is described below:

y - k = C · (x - h)²

Where:

By using this expression, we can find the locations of the vertex and intercepts of the parabola. Now we proceed to find all the required information:

Vertex

y = (x + 5)²

(h, k) = (- 5, 0)

x-Intercepts

(x + 5)² = 0

x = - 5

y-Intercept

y = (0 + 5)²

y = 25

Another point

x = - 1

y = (- 1 + 5)²

y = 4²

y = 16

Finally, we mark the three points on the Cartesian plane and pass a curve through them. The result is shown in the image attached below.

These are our two tables of values for the following functions using the integers from -4 to 4.

A function is defined as a relation between a set of inputs having one output each. function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range. A function is generally denoted by f(x) where x is the input.

Given:

The given functions using the integers from -4 to 4 are

a. F(x)=6/x-2b.

r(x)=6x+12/x²-4

According to given question we have

f(x) = 6/x - 2

Now we just need to evaluate the function in all the given points:

a) f(x) = 6/x - 2

Now we can put the value

f(-4) = 6/(-4) - 2 =  -3/2 - 4/2 = -7/2

f(-3) = 6/-3 - 2 = -4

f(-2) = 6/-2 - 2 = -5

f(-1) = 6/-1 - 2 = -8

f(0) is undefined

f(1) = 6/1 - 2 = 4

f(2) = 6/2 - 2 = 1

f(3) = 6/3 - 2 = 0

f(4) = 6/4 - 2 = -1/2

b. r(x)=6x+12/x²-4

Now we can put the value

r(-4) = 6(-4)+12/(-4)²-4=-27.25

r(-3) = 6(-3)+12/(-3)²-4=-20.66

r(-2) = 6(-2)+12/(-2)²-4=-13

r(-1) = 6(-1)+12/(-1)²-4= 2

r(0) = 6(0)+12/(0)²-4= ∞

r(1) = 6(1)+12/(1)²-4 =14

r(2) = 6(2)+12/(2)²-4=11

r(3) = 6(3)+12/(3)²-4 =15.33

r(4) = 6(4)+12/(4)²-4=20.75

Therefore, these are our two tables of values for the following functions using the integers from -4 to 4.

Using the calorie count C for a serving of food C =5h + 8f + 5​p, the formula for f is derived to be; f = (C - 5h  - 5​p) / 8

An equation is an expression that shows the relationship between two or more numbers and variables.

WE have been Given data that C =5h + 8f + 5​p

Where C is the calorie count, h is the number of grams of carbohydrate, f is the number of grams of fat and p is the number of grams of protein

Now solving for f in the given equation;

C = 5h + 8f + 5​p

Then f the subject of formula;

C - 5h  - 5​p = + 8f

8f = C - 5h  - 5​p

Now dividing through by 8

f = (C - 5h  - 5​p) / 8

Hence, The number of grams of fat, f, contained in a serving of food is; f = (C - 5h  - 5​p) / 8

The linear equation that passes through (-1, 8) and (5,-2) is:

y = (5/3)*x + 29/3

A general linear equation in the slope-intercept form is:

y = a*x + b

Where a is the slope, and b is the y-intercept.

If we know that this line passes trhough the points (-1, 8) and (5, -2) then we can write the slope as:

a = (-2 - 8)/(5 + 1) = -10/6 = 5/3

Then we can write:

y = (5/3)*x + b

Now to find the value of b we can replace the values of one of the points in the line, if we use (-1, 8) we will get:

8 = (5/3)*-1 + b

8 + 5/3 = b

24/3+  5/3 = b

29/3 = b

We conclude that the linear equation is:

y = (5/3)*x + 29/3

Step-by-step explanation:

The number of pounds of steak she buys is 0.82 pounds

From the question, we have the following parameters:

3.5 pounds of steak = $36.75

From the question, we understand that

Hannah spent $8.61 on steak

This means that

x pounds = $8.61

So, we have the following system of equations

3.5 pounds of steak = $36.75

x pounds = $8.61

Cross multiply in the above equation

So, we have

36.75 * x = 3.5 * 8.61

Divide both sides of the equation by 36.75

x = 3.5 * 8.61/36.75

Evaluate the quotient

x = 0.82

Hence, the number of pounds of steak she buys is 0.82 pounds

Roster method is nothing but listing the items of a set inside brackets, the roster method provides a means to display the set's components.

For Example, A={1,2,3,4,5}

The Natural numbers is the category of numbers known as "natural numbers" (n) contains only positive values. They are used in numerical ordering and counting.

They are {N=0,1,2,3,4,......}

Here, x+6=5

Only an integer can meet the condition from the given parameters. This is because an integer has two possible values: positive and negative.

i.e

By adding (-6) to both sides, we have:

When t=0 and t=6s is the time at which the particle have a velocity of 25 m/s and t=3s is the time when acceleration is 0.

a vehicle's capacity to gain speed within a short time

Given s = t^4 − 4t^3 − 36t^2 + 25t

v=d/dt(s)=4t^3-12t^2-72t+25

the particle have a velocity of 25 m/s

So 4t^3-12t^2-72t+25=25

=4t^3-12t^2-72t

=4t(t^2-3t-18)=0

t=0 and

t^2-3t-18=0

(t+3)(t-6)=0

So t=0, t=-3 and t=6

As time>=0, So t=0 and t=6.

Now we required to find acceleration,

Accelaration=d/dt(v)

=d/dt(4t^3-12t^2-72t+25)

=12t^2-12t-72

t=12±√144-4(12)(-72)/24

t=12±60/24

t=12+60/24=3  and 12-60/24=-2

So t=3s

Therefore t=0 and t=6s is the time at which the particle have a velocity of 25 m/s and t=3s is the time when acceleration is 0.

The three solutions to the linear equation are (0, -2), (1, 1) and (2, 4)

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

The linear equation is given as

g(x) = 3x - 2

To determine the solution to the linear equation, we set the value of x to some values

say x = 0, 1 and 2

Substitute x = 0, 1 and 2 in g(x) = 3x - 2

g(0) = 3(0) - 2 = -2

g(1) = 3(1) - 2 = 1

g(2) = 3(2) - 2 = 4

Hence, the three solutions to the linear equation are (0, -2), (1, 1) and (2, 4)
