Ira writes that the sum of a+b is a number that is located a distance of [b] units from a on the number line. Choose four values for a and b and show that this is true. Use the four number lines on the right to show your work and support your answer

Answers

Answer 1

Answer:

1. Take a=4, b=6

a+b

=4+6

=10( Both are positive integers)

2.  a=4 , b= -6

then 4 + (- 6)

= 4 - 6

= -2 [Smaller is positive integer and larger is negative integer , So subtract smaller from larger and apply the sign possessed by larger integer]

3. a = -4, b= -6

a+ b

= -4 -6

=-10 [ Both are negative integers add them apply - sign before the number.]

4. a = -4, b=6

a +b

= -4+ 6

= 2 [one is positive and other is negative subtract smaller from larger and apply positive sign before the number.]

Anna is given the equation 3 + 2x = 2x + 3 The replacement set is {2, 3, 4, 5} Anna says the solution is {3}, but the teacher marked her problem incorrect. Explain what the answer should be and why. Why do you think this is?

Answers

Answer:

The given equation has infinite number of solutions. This means that any real number can be considered a solution to the given equation.

Since the given replacement set {2,3,4,5} consists of real numbers, therefore, the whole set is considered as a solution to the given equation.

This is because, when solving the given equation for x, we will end up with 0 = 0, this means that whatever the value of x is, both sides of the equation will always be equal.

Explanation:

To solve for x, we need to isolate the x on one side of the equation.

This can be done as follows:

3 + 2x = 2x + 3 (subtract 3 from both sides)

2x = 2x (subtract 2x from both sides)

0 = 0

This means that whatever, the value of x is, both sides of the equation will be equal. This means that all real numbers are considered a solution for this equation.

Let's verify this using the given replacement set {2,3,4,5}:

For x = 2:

Left hand side: 3 + 2(2) = 3 + 4 = 7

Right hand side: 2(2) + 3 = 4 + 3 = 7

Both sides are equal.

For x = 3:

Left hand side: 3 + 2(3) = 3 + 6 = 9

Right hand side: 2(3) + 3 = 6 + 3 = 9

Both sides are equal.

For x = 4:

Left hand side: 3 + 2(4) = 3 + 8 = 11

Right hand side: 2(4) + 3 = 8 + 3 = 11

Both sides are equal.

For x = 5:

Left hand side: 3 + 2(5) = 3 + 10 = 13

Right hand side: 2(5) + 3 = 10 + 3 = 13

Both sides are equal.

Hope this helps :)

Enter a recursive rule for the geometric sequence.

2, 6, 18, 54, …

a1= ; an=

Answers

Answer:


Step-by-step explanation:

Given a geometric sequence.

2, 6, 18, 54, …

We have to find the I and nth term.

A geometric sequence. is one where each term is multiplied by a constant value to get the next term.

In our sequence, we find the pattern as each term is multiplied by 3 to get successive terms.

Hence common ratio r = 3

First term = a = 2

For Geometric sequence nth term = a_n = ar^(n-1)

Hence we get a_1 = 2

and a_n =  2(3)^(n-1)

By substituting for n any natural number we can get that term.

Which methods can be used to expand (x+3)3?

Answers

Which methods can be used to expand (x+3)3?

Solution

Here use the Distributive Property of Multiplication Across the Addition.

The Distributive Property is a.(b + c) = a. b + a.c

Using the distributive property, we can expand the given expression.


(x + 3).3 = 3.x + 3.3

That is the expanded form.


The expression (x+3)³ can be expanded by using the binomial expansion method or by multiplying (x+3) by itself three times. This involves using binomial coefficients and combining like terms or calculating the products directly and simplifying the resulting expression.

To expand (x+3)³, we can use binomial expansion, which involves recognizing the pattern of coefficients that arise from Pascal's Triangle or using the binomial theorem. Another way is to multiply (x+3) by itself three times. In both methods, you calculate the products and combine like terms to get the final expanded form.

For cubing of exponentials, such as cubing (x+3), you must calculate each term of the binomial raised to the third power and then combine like terms. The cube of the digit term is calculated as usual, and you multiply the exponents by 3 when dealing with exponential terms.

An example of this concept applied to individual exponentials is: (5³)⁴ = 5³*⁴ = 5¹². In our case of binomial expansion, the expanded form of (x+3)³ would be x³ + 3*x²*³ + 3*x*3² + 3³, which simplifies to x³ + 9*x² + 27*x + 27.

Answer:

Step-by-step explanation:

Final answer:

The equation can be solved using the quadratic formula, resulting in two possible solutions: x = (-3 + √25) / 4 and x = (-3 - √25) / 4.

Explanation:

This equation can be solved using the quadratic formula. For an equation of the form ax² + bx + c = 0, we rearrange it to 2x² - 3x - 2 = x + 4.

Now, using the quadratic formula, we can solve for the values of x:

x = (-b ± √(b² - 4ac)) / (2a)

Substituting the values a = 2, b = -4, and c = -6 into the formula, we get:

x = (-(-3) ± √((-3)² - 4(2)(-2))) / (2(2))

After simplification, we have x = (-3 ± √(9 + 16)) / 4

Which gives us two solutions: x = (-3 + √25) / 4 and x = (-3 - √25) / 4

A. 15.2 units

B. 3.8 units

C. 30.4 units

D. 7.6 units

Answers

Answer:

The correct answer is A. 15.2 units

Step-by-step explanation:

The segment AB is congruent to the segment BC  eg AB≅BC Why?

We can prove it with the triangle congruent theorem, postulate side-side-angle

We are watching triangle ΔABO and triangle ΔCBO, they are congruent

first element side OB=OB - common side

second element side OA=OC=r - radius of the circle

third element angle ∡ABO≅∡CBO=90°

According to the postulate side-side-angle we can conclude that triangles

ΔABO≅ΔCBO (triangles are congruent)

If they are congruent all of their elements are also congruent and therefore also

side AB=BC  => AB+BC=AC,  which is chord  => 7.6+7.6=15.2 units

AC= 15.2 units ( chord )

Answer:

Your answer is B or option 2.

Step-by-step explanation:

When doing scale factors, you will multiply. Always. To get from the original box to the second box, you will multiply by a scale factor of 5/8. An equation can model this. b=5/8a. (Let a = dimensions of original/blue box, let b = dimensions of second/green box).

Since you need to find the dimensions of the first/original box, you need to change b=5/8a to a= [something]. To do that, divide both sides by 5/8. You have b / 5/8 = a. The dimensions of the second box divided by the scale factor 5/8 is the dimensions of the first box. This also makes sense, because the green box looks smaller than the blue box. Hope I helped! This is a challenging subject to explain properly. ^_^"

oh yeah kekeke my name is pizaz/pzaz, what a coinkidink

The answer is D.

Since the original rectangle is bigger, we are going to divide the dimensions in the smaller triangle by the scale factor 5/8. An easy hint to look at in this question is an answer choice that both dimensions are bigger than the dimensions of the smaller rectangle. All the other choices are incorrect because the dimensions of the original triangle are not bigger than that of the smaller triangle which makes them false.

Does This. Graph Represent A Function? Why Or Why Not?

Answers

Answer: D. Yes because it passes the vertical line test.

Step-by-step explanation

A function cannot have duplicate x-coordinates.

When given a table or a set of coordinates, if there is an x-coordinate that is paired with two different y-coordinates then it is not a function.

When given a graph, the simplest way to determine if it is a function is to use the vertical line test.  If you can draw a vertical line anywhere through the graph and it passes through two points, then it is not a function.

In the given graph, it passes the vertical line test so it IS a function.

A taxi service charges $1.00 for the first 1/10 mile then $0.10 for each additional 1/10 mile after that.

Answers

Answer:

y  = 1.00+0.10 x

Step-by-step explanation:

Given that a taxi has a minimum charge of 1 dollar upto 1/10 mile and adds 0.10 for every additional 1/10 mile.

If a person travels <=1/10 miles his charges are 1 dollar

If he travels >1/10 miles charges are 1 dollar +0.10(extra miles 1/10)

Let y be the charges and x be the no of 1/10 miles.

Then the equation for y in terms of x would be

y =1.00 +1/10(x)

y  = 1.00+0.10 x
