Which inequality is true?

Answer:

The greatest common factor for both these numbers is 28

Step-by-step explanation :

First you would try to find the GCF of the two numbers, which is 28. To find this you need to divide the two numbers by the GCF, which may take a few tries. Then, you would have to divide those two numbers by the GCF. Your answer should look like this: 28(3+1).

Step-by-step explanation:

The given steps from the derivation of the quadratic formula are:

Step 3:  \(-c+\frac{b^2}{4a}=a(x^2+\frac{b}{a}x+\frac{b^2}{4a^2})\)

Step 4a: \(-c+\frac{b^2}{4a}=a(x+\frac{b}{2a})^2\)

Step 4b: \(\frac{-4ac}{4a}+\frac{b^2}{4a}=a(x+\frac{b}{2a})^2\)

The property "converting to a common denominator" justifies step 4b. So, option C: "converting to a common denominator" is correct.

The quadratic formula is as follows:

x = [-b ± (√b²+4ac)]/2a

This formula is derived from the quadratic equation \(ax^2+bx+c=0\).

The standard quadratic equation is \(ax^2+bx+c=0\)

Step 1: \(ax^2+bx=-c\)

Step 2: Taking 'a' as common

\(a(x^2+\frac{b}{a}x)=-c\)

Step 3: Adding \(\frac{b^2}{4a}\) on both sides

\(-c+\frac{b^2}{4a}=a(x^2+\frac{b}{a}x)+\frac{b^2}{4a}\)

⇒ \(-c+\frac{b^2}{4a}=a(x^2+\frac{b}{a}x+\frac{b^2}{4a^2})\)

Step 4a: Factoring the polynomial

\(-c+\frac{b^2}{4a}=a(x+\frac{b}{2a})^2\)

Step 4b: Converting to a common denominator

\(\frac{-4ac}{4a}+\frac{b^2}{4a}=a(x+\frac{b}{2a})^2\)

⇒ \(\frac{(-4ac+b^2)}{4a}=a(x+\frac{b}{2a})^2\)

Step 5: Applying square root (on one side there is a square, so, on the other side it gets ±)

⇒ \(\frac{(-4ac+b^2)}{4a^2}=(x+\frac{b}{2a})^2\)

⇒ ±\(\sqrt{\frac{(-4ac+b^2)}{4a^2}} =(x+\frac{b}{2a})\)

⇒ \(x+\frac{b}{2a}\) = ± \(\frac{\sqrt{b^2-4ac} }{2a}\)

step 6: Subtacting \(\frac{b}{2a}\) from both the sides

⇒ \(x=-\frac{b}{2a}\) ± \(\frac{\sqrt{b^2-4ac} }{2a}\)

⇒ x = [-b ± (√b²+4ac)]/2a

Thus, step 4b best explains or justifies the property "Converting to a common denominator".

Answer:

Jalissa paid $35.6 for the jacket at the clearance sale.

Step-by-step explanation:

If the jacket was marked down by 60%, then Jalissa paid 40% of the regular price.

To find out how much she paid, we can start by calculating 40% of the regular price:

40% of 89 = 0.40 x 89 = 35.6

So Jalissa paid $35.6 for the jacket at the clearance sale.

Answer:

The area of polygon MNOPQR = Area of a rectangle that is 15 square units + Area of a rectangle that is 2 square units.

In the given polygon MNOPQR, side MN is parallel to side RQ and the side MR is parallel to side PQ

We will draw a perpendicular line from point O on the side RQ, which will intersect RQ at point S. So, we can now divide the whole polygon into two different rectangles MNSR and OPQS with the areas as A₁ and A₂ respectively.

In rectangle MNSR, length(MN) = 5 units and width (MR) = 3 units

According to the formula for Area of rectangle,

A₁ = (length)×(width)

A₁ = (5 units)×(3 units)

A₁ = 15 square units

Now in rectangle MNSR, side MN= side RS and side MR = side NS,

so RS= 5 units and NS= 3 units

That means, SQ= RQ- RS = 7-5 = 2 units

and OS= NS - NO = 3- 2 = 1 unit

In rectangle OPQS, we have length(SQ) = 2 units and width(OS) = 1 unit

So, A₂ = (length)×(width)

A₂ = (2 units)×(1 unit)

A₂ = 2 square units

So, the area of polygon MNOPQR = (Area of a rectangle that is 15 square units + Area of a rectangle that is 2 square units)

Step-by-step explanation:

The required probability that William worked on last year was an anniversary party is 1/ 36.

As mentioned in the quesiton,
William is a very busy professional DJ. Last year, he worked at 10-anniversary parties and 26 other events.

Probability can be defined as the ratio of favorable outcomes to the total number of events.

Here,
Total sample space = 26 + 10 = 36
Number of favorable outcomes = 1
the probability that William worked on last year is was an anniversary party,
= Favorable outcome/sample space
= 1 / 36

Thus, the required probability that William worked last year is 1/ 36.

Answer:

To solve the equation -(x + 3) = 2(x - 3) for x, we can follow these steps:

Step 1: Distribute the negative sign on the left side of the equation:

-(x + 3) = 2(x - 3)

=> -x - 3 = 2(x - 3) (using the distributive property)

Step 2: Expand the right side of the equation:

-x - 3 = 2x - 6

Step 3: Add x to both sides of the equation to isolate the x term on one side:

-x + x - 3 = 2x + x - 6

=> -3 = 3x - 6

Step 4: Add 6 to both sides of the equation:

-3 + 6 = 3x - 6 + 6

=> 3 = 3x

Step 5: Divide both sides of the equation by 3 to solve for x:

3/3 = 3x/3

=> 1 = x

So, the correct value of x that makes the equation true is B. 1.

PLEASE MARK BRAILYISTT :D

Answer:

B, one

Step-by-step explanation:

In order to solve this, you can solve the equation. First, you can use the distributive property to get -x-3=2x-6. If you make the variables on one side and the constants on the other, you will get -3x-3=-6. This can further simplify to -3x=-6. Divide both sides by -3 to get that x=1. Then, the correct answer is B.

Probability of rolling a number less than 3: 2/6 or 1/3

Step-by-step explanation:

Explanation: Out of the six possible outcomes (numbers 1, 2, 3, 4, 5, 6), there are two outcomes that meet the condition of rolling a number less than 3, which are 1 and 2. Therefore, the probability of rolling a number less than 3 is 2 out of 6, which simplifies to 1/3.

Probability of not rolling a number less than 3: 4/6 or 2/3.

Explanation: To find the probability of not rolling a number less than 3, we consider the outcomes that are not favorable (i.e., rolling a 3, 4, 5, or 6). There are four such outcomes, so the probability of not rolling a number less than 3 is 4 out of 6, which simplifies to 2/3. :D

Solving problem #1 as an example:

-Set up an equation with two "fractions" equal to eachother.

-have the total amount (196) equal 100

ex. ?/196 = ?/100

-then find the percentage asked b placing the percent over 100

ex. 5/100

- from there solve by multiplying the percent (5) to the total amount (196) and divide that answer by 100.

-finally you should get your answer of 9.8

*** to check your work simply set up your answers

ex. 9.8/196 = 5/100

and multiply the numbers diagonally from eachother

ex. 9.8×100 and 196×5

If your answer is correct, you should get the same number on both sides
