What is the circumference of a tire with a radius of 22 centimeters

x = –5 or x = 3

Solution:

Given expression:

[tex]|-1-x|=4[/tex]

[tex]\Rightarrow |-x-1|=4[/tex]

⇒ –x – 1 = 4 or –x – 1 = 4

First take –x – 1 = 4.

Add 1 on both side of the equation.

⇒ –x – 1  + 1 = 4 + 1

⇒ –x = 5

Divide by –1 on both side of the equation, we get

⇒ x = –5

Now take –x – 1 = –4.

Add 1 on both side of the equation.

⇒ –x – 1  + 1 = –4 + 1

⇒ –x = –3

Divide by –1 on both side of the equation, we get

⇒ x = 3

x = –5 or x = 3

Hence the two values of x are –5 or 3.

Answer:

  79°

Step-by-step explanation:

Label the intersection of AE and CD point F. Then angle CFE is an alternate interior angle with angle BAE, so is congruent. The angle of interest is an exterior angle to triangle CFE, so is the sum of remote interior angles CFE (54°) and DCE (25°). That sum is ...

  m∠AEC = 54° +25° = 79°

Based on the definition of alternate interior angles, the measure of ∠AEC is: 79°

Interior angles that are alternating each other on a transversal are congruent, and are called alternate interior angles.

Thus:

m∠AEC = m∠BAE + m∠FCE

Substitute

m∠AEC = 54° + 25°

m∠AEC = 79°

Therefore, based on the definition of alternate interior angles, the measure of ∠AEC is: 79°

Answer:

n = - 4

Step-by-step explanation:

Given

6n - 2(4n + 7) + 4 = - 2 ← distribute and simplify left side

6n - 8n - 14 + 4 = - 2

- 2n - 10 = - 2 ( add 10 to both sides )

- 2n = 8 ( divide both sides by - 2 )

n = - 4

To solve the equation 6n - 2(4n + 7) + 4 = -2, we apply the distributive property and combine like terms to simplify. The solution is n = -4.

To solve the equation 6n - 2(4n + 7) + 4 = -2, we need to apply the distributive property and combine like terms to simplify.

Answer:

In mathematics, a function (f) is a relationship between a given set X (called domain) and another set of elements Y (called codomain) so that each element x of the domain corresponds to a single element f (x) of the domain (the that form the route, also called scope ranking).

See: Relations and functions

In everyday or simpler language, we will say that mathematical functions are equivalent to the common logical process that is expressed as "dependent on."

Mathematical functions can refer to everyday situations, such as: the cost of a phone call that depends on its duration, or the cost of sending a parcel that depends on its weight.

As an example, what would be the rule that relates the numbers on the right with those on the left in the following list ?:

1 --------> 1

2 --------> 4

3 --------> 9

4 --------> 16

The numbers on the right are the squares of those on the left.

The rule is then to "square":

1 --------> 1

2 --------> 4

3 --------> 9

4 --------> 16

x --------> x 2.

To refer to this rule we can use a name, which is usually the letter f (of function). So, f is the rule "square the number".

Usually two notations are used:

x --------> x 2 or f (x) = x 2.

Thus, f (3) means applying the rule f to 3. Doing so results in 3 2 = 9.

Then f (3) = 9. Similarly f (2) = 4, f (4) = 16, f (a) = a 2, etc.

Louise’s answer is not correct

Step-by-step explanation:

Let us revise how to solve (ax + b)²

The answer of square a binomial contains three terms: (1st)² + 2(1st)(2nd) + (2nd)²

∵ The bracket is (5x³ + 3)²

- Square the first term

∴ The first term of the answer = (5x³)² = (5)²(x³)² = [tex]25x^{6}[/tex]

- Multiply the 1st , the 2nd term and 2

∴ The second term of the answer = 2(5x³)(3) = 2(5)(3)x³ = 30x³

- Square the 2nd term

∴ The third term of the answer = (3)² = 9

∴ (5x³ + 3)² =  [tex]25x^{6}[/tex] + 30x³ + 9

∵ Louise’s answer is (5x³)² + (3)² =  [tex]25x^{6}[/tex] + 9

Answer:

Sample Response: Louise’s answer is not correct. She is missing the term 30x3. When squaring a binomial, it is best to write the product of the binomial times itself. Then you can use the distributive property to multiply each term in the first binomial by each term in the second binomial. Louise also could have used the formula for a perfect square trinomial, which is found by squaring a binomial.

Answer:

Step-by-step explanation:

Answer: 5, 12, 13

Step-by-step explanation:

Answer:

1. 60 miles per hour

2. Yes, linear

3. Y=60x

Step-by-step explanation:

1. Speed is 60 miles per hour.

2. A function relationship is a relationship between two variables.

3. The rule to represent the function is Distance = 60t.

1. What is the speed?

The speed of the car is the rate at which it is traveling. It is calculated by dividing the distance traveled by the time taken to travel that distance.

Speed = Distance / Time

From the graph, we can see that the car travels 120 miles in 2 hours. Therefore, the speed of the car is:

Speed = 120 miles / 2 hours = 60 miles per hour

2. Is this a function relationship?

A function relationship is a relationship between two variables where each input value has only one output value. In other words, for every value of the independent variable (in this case, time), there is only one corresponding value of the dependent variable (in this case, distance).

We can see from the graph that the distance traveled by the car increases linearly with time. This means that there is a one-to-one relationship between the two variables, and therefore the relationship is a function.

3. If this is a function, write a rule to represent it.

A rule for a function is a mathematical expression that shows how the dependent variable is related to the independent variable. In this case, the rule for the function would be:

Distance = Speed * Time

Substituting the speed of the car into the rule, we get:

Distance = 60 miles per hour * Time

Therefore, the rule to represent the function is:

Distance = 60t

where t is the time in hours.

Step-by-step explanation:

The expression [tex]8x^2 + 10x[/tex] factors to [tex]2x(4x + 5)[/tex] and has solutions x = 0 and x = -5/4.

We first need to understand what it represents. In this expression, [tex]x[/tex] is the variable, and the terms [tex]8x^2[/tex] and [tex]10x[/tex] are polynomial terms where:

[tex]8x^2[/tex] indicates that the variable [tex]x[/tex] is raised to the power of 2, meaning it is multiplied by itself ([tex]x \times x[/tex]) and then scaled by a factor of 8.

[tex]10x[/tex] means that the variable [tex]x[/tex] is multiplied by 10.

The first term is [tex]8x^2[/tex].

The second term is [tex]10x[/tex].

In this case, the terms are not like terms because one is [tex]x^2[/tex] and the other is [tex]x[/tex]. Therefore, they cannot be combined further. The expression is simplest as it stands, which is:  [tex]8x^2 + 10x[/tex]

Factoring out [tex]2x[/tex] gives us:

[tex]2x(4x + 5)[/tex]

Thus, [tex]8x^2 + 10x[/tex] can also be expressed as [tex]2x(4x + 5)[/tex]. This is useful if you are trying to find the roots of the equation (setting it equal to zero) since it can help identify the values of [tex]x[/tex] that satisfy the equation [tex]8x^2 + 10x = 0[/tex].

This gives two possible solutions for x:

2 * x = 0 which leads to x = 0

4 * x + 5 = 0 which leads to x = -5/4

Answer:4.21,4.22,4.23, 4.24

Step-by-step explanation:

4 1/5 is 4.2 as a decimal and the numbers between 4.2 and 4.5 as numbers with 2 places past the decimal place are the ones above.

The number with two decimal places that are bigger than 4(1/5) and smaller than 4.25 is 4.22.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

4(1/5)

= 21/5

= 4.2

Now,

Two decimal numbers between 4.2 and 4.25.

4.21, 4.22, 4.23, and 4,24.

Thus,

The number is 4.22.

Explanation:

If points F and E are the midpoints of segment VU and segment ST respectively, then segment FE is the midsegment of the trapezoid. The midsegment is parallel to the bases, and the midsegment's length is found by adding up the bases VS and UT, then dividing by 2.

(VS + UT)/2 = FE

(29 + x+17)/2 = 23 ... plug in given info; isolate x

(x+46)/2 = 23

x+46 = 23*2 ... multiply both sides by 2

x+46 = 46

x = 46-46 ... subtract 46 from both sides

Given data:

m∠P = m∠R and TP = SR

To prove that ΔQTP ≅ ΔQSR:

Consider ΔQTP and ΔQSR,

m∠P = m∠R (given angle)

TP = SR (given side)

m∠Q = m∠Q (common angle)

∴ ΔQTP ≅ ΔQSR (by ASA congruence rule)

Hence ΔQTP and ΔQSR are congruence triangles by Angle - Side - Angle congruence rule.
