Find 4 on the x-line (the horizontal line).

Find where the red line crosses through that is where the 4 is at.

Once you find it, trace the line in which the 4 is x, and find the y.

The line gives (4, -1)

Find the slope of the line.

(4, -1) = (x₁ , y₁)

(0, 2) = (x₂ , y₂)

slope = (y₂ - y₁)/(x₂ - x₁) = (2 - (-1)/(0 - 4) = 3/-4

y = (-3/4)x + b

Plug in a point, for example (0, 2)

2 = (-3/4)0 + b

Simplify

2 = 0 + b

b = 2

Plug in 2 for b

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

f(x) = (-3/4)x + 2 is your equation.

Now, plug in 4 for x (as you are solving for x.

f(x) = (-3/4)(4) + 2

Simplify

f(x) = -3 + 2

f(x) = -1

-1 is your function when x = 4

Answer:

Mr. Aroxa is correct.

Step-by-step explanation:

Since we know that polynomials are closed under addition, subtraction and multiplication as when we will add, subtract or multiply two polynomials we will get a polynomial.

Polynomials are not closed under division because division of two polynomials is not necessarily a polynomial.

We can see it by dividing a binomial by a trinomial. This division will result in a rational expression and it will have negative exponent. Negative exponents are not allowed in polynomials.

Therefore, Mr. Aroxa is correct.

The answer would be: If Leo has d dollars, then dale has 2d+3 dollars.

Hope this helps!

Answer:

Option b)  If Leo has d dollars, then Dale has 2d + 3 dollars.  

Step-by-step explanation:

We are given the following information in the question:

Let Leo has d dollars.

It is given Dale has three dollars more than twice the money Leo has.

Thus, according to the question Dale's money can be expressed with the help of an equation:

[tex]\text{Dale's money} = 3 + 2\times \text{Leo's money}\\\text{Dale's money} = 3 + (2\times d) = 3 + 2d[/tex]

Thus, option b) is the correct representation of Dale's money.

If Leo has $d, the, Dale have $(3 + 2d).

With out any functions to choose from...this is difficult.  But look for the equation that has a a decimal raised to a power (.07)^2

Remark

All you need do is subtract the beginning amount from the ending amount

Givens

Ending Amount (E) = 3.56

Beginning Amt (B) = 2.95

Amt Added (A) =         ?

Solution

A = E - B                 Substitute values

A = 3.56 - 2.95      Combine Like terms on the left

A = 0.61 mL           Answer

This is a proportion, once you set it up (the hard part) the calculations are easy.

[tex]\frac{21.6mi}{1gal} = \frac{x}{6.2gal}[/tex]

Now, just cross multiply

x = 133.92 mi

Cheryl travel 133.92 miles on 6.2 gallon of gas if Cheryl can travel 21.6 miles on one gallon of gas.

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

We have:

Cheryl can travel 21.6 miles on one gallon of gas.

Let's suppose Cheryl travel x miles on 6.2 gallon of gas.

x = 6.2×21.6 = 133.92 miles

Thus, Cheryl travel 133.92 miles on 6.2 gallon of gas if Cheryl can travel 21.6 miles on one gallon of gas.

Let us first describe how partial product and regrouping are alike:

Partial Products and Regrouping are alike because both methods are multiplied by one number and if the product of the number has 2 digits it can be carried.

Now let us discuss how they are different:

Partial Products and Regrouping are different because Partial Products are doing multiplication step by step and regrouping is regular multiplication.

the answer is 763 because 763 - 763 = 0

I don't want to sound rude here or anything but common sense would tell you it's 763. If you read and understand the problem it would be easy. Also if you add 763 to 0 you would get itself. Its just asking you to subtract 763 from itself. hope this helps!! :)

Where are the images?

x^2-25 would be your answer

use the FOIL method: First, Outer, Inner, Last.

first: x*x = x^2

outer: x*-5 = -5x

inner: 5*x = 5x

last: 5*-5 = -25

put together: x^2 - 5x + 5x - 25

simplify: x^2 - 25

That would be 236. Quotient means divide the numbers from one another.

Hope I could help! :)

Answer:

0 - 0.23 - 1.02 - 3/2 - 1.89 - 1.98 - 13/5

Step-by-step explanation:

We have to put the number in an increasin order:

0 - 0.23 - 1.02 - 3/2 - 1.89 - 1.98 - 13/5 or

0 - 0.23 - 1.02 - 1.5 - 1.89 - 1.98 - 2.6

Let the number be X

According to question

3 less than 3 times a number = 23 less than half the number

3X-3 = 1/2 X -23

3X - 1/2X = -23+3

Taking LCM

(6X-X)/2 =-20

5X = -20×2

5X = -40

X = -40/5

X= -8

-30 feet

below meaning negative.

the answer would be -30 because its below the sea level if it was positive

it would say above sea level and that would be positive 30

but in this case its -30

Find out how much money one woman would pay a year by multiplying $140 and 12 months together like this.

140×12=1680

Next, find out how much she'd be paying for 20 years by multiplying the product by the years like this.

1680×20=33600

Now, to find out how much money all 1000 women are paying for the 20 years, multiply the previous product with the number of women.

33600×1000=3600000

Therefore, all 1000 women would be paying $3,600,000 total during the 20 year time period.

Rational although it does repeat it is considered rational numbers that are 0 and are fractions are not considered rational such as square roots too.

Here is some helpful information: Also any decimal number that is repeating can be written in the form a/b with b not equal to zero so it is a rational number.

i believe the formula you need is; SA= n(3/10 ib) + 9b

Answer:  The required quantity of garlic used is 0.67 cloves.

Step-by-step explanation:  Given that a bread recipe uses 3 tablespoons of olive oil for every 2 cloves of crushed garlic.

We are to find the quantity of garlic that is used for one tablespoon of olive oil.

We will be using the UNITARY method to solve the given problem.

We have

quantity of garlic that is used for 3 tablespoons of olive oil = 2 cloves.

So, the quantity of garlic that is used for 1 tablespoon of olive oil will be

[tex]\dfrac{2}{3}=0.6666....=0.67~\textup{cloves}.[/tex]

Thus, the required quantity of garlic used is 0.67 cloves.

Answer:

18 Tala.

Step-by-step explanation:

1. You have that Ming learned that the exchange rate is 6 Tala for $2. Therefore, if she exchanged $6, she would get:

[tex]\frac{6}{2}=\frac{x}{6}[/tex]

2. Now, you must solve for [tex]x[/tex], which is sthe amount of Tala:

[tex]x=\frac{(6)(6)}{2}\\x=\frac{36}{2}\\x =18[/tex]

3. Therefore, she would get 18 Tala.

CF + FE = CE.  Since F is the midpoint, then CF = FE, So, CF + CF = CE ⇒ 2CF = CE

Now, set up the proportion:

[tex]\frac{BF}{CF} = \frac{AE}{CE}[/tex]

[tex]\frac{23}{CF} = \frac{5x - 4}{2CF}[/tex]    substituted known values

23(2CF) = CF(5x - 4)   cross multiplied

23(2) = 5x - 4      divided both sides by CF

46 = 5x - 4    simplified

50 = 5x         added 4 to both sides

10 = x           divided both sides by 5

Answer: 10

Substitute:

[tex]\dfrac{-1+x_B}{2}=5\qquad|\cdot2\\\\-1+x_B=10\qquad|+1\\\\x_B=11\\\\\dfrac{4+y_B}{2}=4\qquad|\cdot2\\\\4+y_B=8\qquad|-4\\\\y_B=4[/tex]

A fact family is a group of math facts using the same numbers.

Example:

Using the numbers: 5, and 2,

5 ∙ 2 = 10

2 ∙ 5 = 10

10 ÷ 2 = 5

10 ÷ 5 = 2

A fact family is a set of related math facts using the same numbers to show the relationship between addition and subtraction or multiplication and division.

Definition of a Fact Family

A fact family in mathematics consists of a group of related math facts that use the same set of numbers. Specifically, in the context of addition and subtraction or multiplication and division, fact families demonstrate the relationship between these operations. For example, with the numbers 2, 4, and 6, a fact family would include the following equations: 2 + 4 = 6, 4 + 2 = 6, 6 - 2 = 4, and 6 - 4 = 2. Each pair of arithmetical operations, being related by inverse functions, create the concept of a fact family, illustrating how numbers and operations are interconnected.

f(n) = f(n - 1) - 5

f(1) = 2

f(2) = f(2 - 1) - 5 = 2 - 5 = -3

f(3) = f(3 - 1) - 5 = f(2) - 5 = -3 - 5 = -8

f(4) = f(4 - 1) - 5 = f(3) - 5 = -8 - 5 = -13

f(5) = f(5 - 1) - 5 = f(4) - 5 = -13 - 5 = -18

f(6) = f(6 - 1) - 5 = f(5) - 5 = -18 - 5 = -23
