they are both quadrilaterals and have 4 vertices

Step-by-step explanation:

Answer:

The correct answer is A.

Step-by-step explanation:

In order for a set to be a solution set, all of the numbers in the set must satisfy the equation. In this case, we are looking to satisfy the equation x < 14. So we must be able to tell that every number in the set is less than 14. In each of the sets (except for A), there is at least one number that is greater than 14. There are no numbers greater than 14 in A.

Final answer:

The equation that best models the situation of the pizza delivery worker's scooter mileage is 50d = 12,900, where d represents the number of days worked.

Explanation:

The question asks us to find out which equation best models the situation where a pizza delivery worker drives a certain number of miles after d days of pizza delivery. To start, the worker bought a scooter with 12,100 miles on it. Each day of work he adds 50 miles to the total. After d days of delivery, the total miles driven on the scooter equals 25,000. We are looking for an equation that represents this scenario.

The total mileage on the motor scooter after d days can be calculated by the initial mileage plus the product of the number of days and the average miles driven per day. Mathematically, this is represented by:

12,100 miles + 50 miles/day × d days = 25,000 miles

To find the equation that models this situation, we subtract 12,100 from both sides to isolate the term with d on one side:

50d = 25,000 - 12,100

So, the equation that models this situation is:

50d = 12,900

If ABCD is the rectangle, then AB and BC are perpendicular.

Let m₁ and m₂ - slopes of perpendicular lines. Therefore

m₁m₂ = -1 → m₂ = -1/m₁.

We have m₁ = 2/3 then m₂ = -1/(2/3) = -3/2.

The slope of BC is -3/2.

The equation of the straight line has its slope and given point.

If we have a non-vertical line that passes through any point(x1, y1) has gradient m. then general point (x, y) must satisfy the equation

y-y₁ = m(x-x₁)

We are given ABCD is the rectangle, then AB and BC are perpendicular.

Let m₁ and m₂ are slopes of perpendicular lines. Therefore.

m₁m₂ = -1

m₂ = -1/m₁.

We have m₁ = 2/3 then;

m₂ = -1/(2/3) = -3/2.

Hence, The slope of BC is -3/2.

Answer:

Everything should simplify down to -9a-3 (your answer)

Step-by-step explanation:

Distributive property is basically multiplying the outside number into the inside parenthesis ().  Basically #(a)--->#a        or   #(a+b)---> #a+#b

Since you're not ask to solve for anything but simplify, just multiply 3 to -3a and -1.....

so 3*-3a is -9a and 3*-1 is -3      and you have 3(-3a-1)= -9a-3

Final answer:

The distributive property is a mathematical property that allows us to distribute multiplication over addition or subtraction. It helps simplify expressions and perform calculations more efficiently in algebra and arithmetic.

Explanation:

The distributive property is a mathematical property that allows us to distribute multiplication over addition or subtraction. It states that for any numbers a, b, and c, the expression a * (b + c) is equal to a * b + a * c. This property helps us simplify expressions and perform calculations more efficiently.

For example, if we have the expression 3 * (2 + x), we can use the distributive property to simplify it to 3 * 2 + 3 * x, which becomes 6 + 3x. This allows us to break down the calculations into smaller steps and avoid errors.

The distributive property is one of the fundamental properties of multiplication and is widely used in algebra and arithmetic.

Answer:

UV =2

Step-by-step explanation:

From the diagram

TV = x+14

TV = TU + UV

x+14 = 9+ 8+2x

Combine like terms

x+14 = 17+2x

Subtract x from each side

x-x+14 = 17+2x-x

14 = 17+x

Subtract 17 from each side

14-17 = 17+x-17

-3 =x

But we are not asked to solve for x, but for UV

UV = 8+2x

Substitute x=-3

UV = 8+2(-3)

UV  = 8-6

UV =2

35/23 is an improper fraction because the numerator is larger than the denominator.

To convert to a mixed number, use long division to find 35 into 23 goes in exactly one whole time (quotient) and there is 12 leftover (remainder)

You can see it through doing it like this

35/23 = (23+12)/23 = 23/23 + 12/23 = 1 + 12/23 = 1 & 12/23

So in short, 35/23 = 1 & 12/23

1 & 12/23 is a mixed number with 1 as the whole part and 12/23 as the fractional part.

---------------------

Real life example: if you had 35 cookies and 23 friends, then each friend would get 1 whole cookie. There would be 12 cookies left over.

The question involves understanding improper fractions, specifically 35/23. This fraction is already improper as the numerator is larger than the denominator and it cannot be simplified further.

The student's question pertains to converting an improper fraction, which in this case is 35/23. To clarify, an improper fraction is one where the numerator (the top number) is larger than the denominator (the bottom number). This type of fraction represents a quantity greater than one whole. The student's example already is an improper fraction.

There is no further calculation needed unless the goal is to convert it to a mixed number or to its simplest form, which cannot be done in this case since 35 and 23 have no common factors besides 1.

f(-3) = -1

f(-1) = 2

f(3) = 5

======================================

Explanations:

Draw a vertical line through -3 on the x axis. Make sure this vertical line crosses the orange graph. Mark this point of intersection and then draw a horizontal line from this point to the y axis. You should find that it touches -1 on the y axis. Check out the attached image to see this process in action.

Those steps basically say that x = -3 leads to y = -1. Since y = f(x), this means f(-3) = -1

Through similar steps, you should find that f(-1) = 2 and f(3) = 5

Note that the open hole/circle does not count. So if you land on an open hole, just keep going until you hit a closed circle on the other piece of the graph.

A) f (–3) = -1

B) f (–1) = 2

C) f (3) = 5

1. graph 1 is a straight line that passes through 2 points : (-4.0) and (-1, -3) so that the straight line equation:

[tex]\rm \dfrac{y-0}{-3-0}=\dfrac{x+4}{-1+4}\\\\\dfrac{y}{-3}=\dfrac{x+4}{3}\\\\3y=-3(x+4)\\\\3y=-3x-12\\\\y=-x-4\Rightarrow \:for\:x<-1[/tex]

2. graph 2 is a straight line with the equation: \

[tex]\rm y=2\Rightarrow \:for\:-1\leq x<3[/tex]

3. graph 1 is a straight line that passes through 2 points,  (3.5) and (5.1) so that the straight line equation  :

A function made up of 3 pieces:

a solid dot means "including",

an open dot means "not including"

[tex]\rm y=-x-4\:for\:x<-1[/tex]

[tex]\rm y=2\:for\:-1\leq x<3[/tex]

f (-3) = - (- 3) -4

f (-3) = 3-4

f (-3) = -1

B) f (–1) =

Because x = -1, the function used y = 2, so

f (-1) = 2

C) f (3) =

Answer:

16.6%

Step-by-step explanation:

Answer: $9.83

Step-by-step explanation:You need to calculate

($880/month)(.1665)(1/12) = $12.21

($880/month)(.0325)(1/12) = $2.38

Difference = $12.21 - $2.38 = $9.83

The Interest does your friend save at the end of the first month by Paying you instead of Credit Card is dollar 9.83.

What is Simple Interest?

''Simple Interest is a fee paid for borrowing money. The amount borrowed is called Principal the interest is expressed as a Percentage Rate of  the Interest".

What is Rate of  the Interest?

"Rate of  the Interest is the amount a lender charges a borrower and is a Percentage of the Principal - the amount loaned".

According to the question

Credit Balance is taken as Principal(P) = $880.00

Rate of Interest = 16.65%

Number of years = [tex]\frac{1}{12}[/tex]

Formula for Simple Interest = [tex]\frac{pnr}{100}[/tex]

Simple Interest=  [tex]\frac{(880)(1)(16.65)}{(12)(100)}[/tex]

=  12.21

Friend Pay you of Rate of Interest = 3.25%

Formula for Simple Interest is= [tex]\frac{pnr}{100}[/tex]

=[tex]\frac{(880)(1)(3.25)}{(12)(100)}[/tex]

= 2.38

In order to find the saving money make if Difference between Simple Interest paid at rate of interest 16.65% and Simple Interest paid at rate of Interest 3.25%

=  12.21 - 2.38

=  9.83

Hence, the Interest save at the end of the first month by paying you instead of the credit card $9.83.

Answer:

[tex]0\leq g\leq 14[/tex]

Step-by-step explanation:

The function is defined as [tex]m(g)[/tex], that is, the independent variable represents gallons, and the dependent variable represents miles, depending on the gallons of gas, the car will move certain number of miles.

Knowing the relation between the variables of the function, we also can know that the fuel tank holds 14 gallons, that is, the independent variable holds 14 units, and the independent variable is [tex]g[/tex].

Remember that the domain is the set that represents all valid values that the independent variable can take. In this case

[tex]0\leq g\leq 14[/tex]

Which means that the fuel tank can hold a maximum of 14 gallons and a minimum of 0 gallons. Therefore, the domain is

The property in expression is Associative property.

The characteristics of addition specify the possible methods for adding the given integers. One of the fundamental arithmetic operations in mathematics is "addition." The process of adding items together is called addition. The "+" symbol is used to add the two numbers together. The numbers we will add are referred to as "addends," and the outcome will be referred to as "sum." Any two or more digit numbers, known as addends, are used in the addition process.

Given expression

(m + 7.3) + 4.1 = m + (7.3 + 4.1)

this shows

(A + B) + C = A + (B + C)

this is associative property,

According to this property or law, the addition of three integers yields the same result regardless of how the numbers are arranged. It means that even if the order of the addends is modified while adding three or more numbers, the total or sum will remain the same.
