Multiplication property of equalityDivision property of equality

How to solve equation with reasons?

The equation given is as follows:

3x / 6 = 4 . This equation is given.

Therefore,

3x / 6 = 4

Using multiplication property of equality, we will multiply both sides of the equation by 6.

3x / 6 × 6 = 4 × 6

3x = 24

The multiplication property of equality states that when we multiply both sides of an equation by the same number, the two sides remain equal.

Hence,

3x = 24

Using division property of equality, we divide both sides by 3.

3x / 3 = 24 / 3

x = 8

The Division Property of equality says that dividing both sides of an equation by the same number does not affect the equation.

1 The midpoint of AB is M. If the coordinates of A are (2,-6) and the coordinates of Mare (5, -1), find the coordinates of B.

Answers

The midpoint of two points is given as

(x1 + x2)/2, (y1 + y2)/2

Given that the coordinates of the midpoint are (5, -1), let the coordinates of point B be x2 and y2

(2 + x2)/2 = 5

2 + x2 = 10

x2 = 10 - 2

x2 = 8

(-6 + y2)/2 = -1

-6 + y2 = -2

y2 = -2 + 6

y2 = 4

The coordinates of B are (8,4)

This shows a scale drawing of Javier's room. The scale of his room is 1 cm = 2 ft. 5 cm 6.5 cm How much carpet does Javier need to purchase to completely cover his floor? A 130 square feet B. 120 square feet C. 111 square feet​

Answers

Answer:

A 130 ft²

Step-by-step explanation:

if I understand this right, then the scale is 1 cm on a drawing is 2 ft in reality.

the room in the drawing measures 5 cm × 6.5 cm.

the question about how much carpet is needed is the question about the area of the floor of the rectangle room.

first e need to get the real measurements :

5 cm = 5×1 cm = 5 × 2 ft = 10 ft

6.5 cm = 6 5×1 cm = 6.5×2 ft = 13 ft

so, the real room is 10 ft × 13 ft.

and the area is therefore 130 ft².

A booth at the State Fair recorded the number of items sold in the chart below. What is the ratio of lemonade and sodas sold to the number of candy bars sold?

Answers

Answer:

7:6

Step-by-step explanation:

add the amount of lemonade and soda together, that is 42.

so you have 42:36.

you need to simplify it, so you divide 42 / 2 = 21

then you divide 36 / 2 = 18.

so now you have 21:18.

then you divide 21 / 3 = 7

then you divide 18 / 3 = 6.

so therefore, your answer is 7:6.

Trinomial: 2x^2 + 11x - 6

Step-by-step explanation:

Hello! Let's help you with your question here!

So, box method. From your question, the process is pretty easy. It would require a bit more work when factoring a trinomial.

The equation in question is already factored which is very useful, now it's a matter of the values in the box. I am on the assumption that the two top boxes and the two left boxes are filled in for you and you just need to fill the middle (if that isn't the case, do let me know). To just fill the boxes in the middle, evaluate it like you would multiplying rows and columns. So, it would be as such:

       6      x

-1    -6      -x

2x  12x    2x^2

In terms of simplifying, we use FOIL to expand it out into a trinomial and collect like terms. Therefore, it becomes:

[tex](x+6)(2x-1) = (x*2x)+(x*(-1))+(6*2x)+(6*(-1))[/tex]

[tex]= 2x^2 + (-x) + (12x) + (-6)[/tex]

Answers

We have a piecewise function that we should evaluate based on the condition of the independent variable

It is the value of the independent variable that will dictate which of the two equations to use

We can see that the value of the independent variable given is -3

Mathematically, -3 is not greater than 3; so this means the value of the independent variable given falls within the domain of the second part of the piece-wise function

Hence, we are to evaluate f(x) = -(x + 1) at the point x = -3

Thus;

f(-3) = -(-3 + 1)

f(-3) = -(-2)

f(-3) = 2

Find the values at the 25th and 60th percentiles for the data set. The value at the 25th percentile is_____.

Answers

Answer:

25th percentile: 5

60th percentile: 12

Explanation:

To find the percentile, we need to organize the data from lowest to greatest, so

1 3 4 4 5 6 6 7 8 8 9 12 14 15 17 17 19 20 20 20

Therefore, there are 20 values in the data set.

The position of the 25th percentile can be calculated as:

[tex]\frac{25(n)}{100}=\frac{25(20)}{100}=5[/tex]

Then, the position of the 25th percentile is 5th. In this case, the number in this position is 5 so the 25th percentile is 5

In the same way, we can calculate the position for the 60th percentile as follows:

[tex]\frac{60(n)_{}}{100}=\frac{60(20)}{100}=12[/tex]

Then, the position of the 60th percentile is the 12th. In this case, this value is 12, so the 60th percentile is 12.

So, the answers are:

25th percentile: 5

60th percentile: 12

Jennifer made a cake and brownies. Her cake dish was 8 inches long, 5 inches wide and 2 inches deep. Her brownie tin was 9 inches long, 4 inches and 2 inches deep. Which dish has a larger volume? By how much?

Answers

Answer:

The cake is larger by 8 in^3

Step-by-step explanation:

The volume equals the product of the length of all 3 sides, or length * height * width

The volume of the cake is 8in*5in*2in which equals 80 in^3

The volume of the brownie tin is 9in*4in*2in which is 72 in^3

Clearly, the cake has more volume since 80 in^3 > 72 in^3

It is greater by the brownie tin by  80 in^3 - 72 in^3, or 8 cubic inches.

What is the equation of the line that is parallel to the line y = x + 4 and passes through the point (6, 5)?y = x + 3y = x + 7y = 3x – 13y = 3x + 5

Answers

You have to find a line that is parallel to y=x+4 and passes through the point (6,5)

Parallel lines always have the same slope.

The slope of the line is the coefficient that multiplies the x term, in this case, there is no number multiplying "x" but that does not mean that the line has no slope, turns out that the line has a slope equal to "1" when the variables (letters in an equation) are "alone" the coefficient is 1

So for both lines, the slope is

[tex]m=1[/tex]

Using the slope and the known point of the line, you can determine the equation of said line by using the "point-slope" form

[tex]y-y_1=m(x-x_1)[/tex]

Where

(x₁,y₁) are the coordinates of a point of the line

m is the slope

Replace the coordinates of the point and the slope in the formula

[tex]y-5=1(x-6)[/tex]

Next is to solve for y to express it in slope-intercept form

[tex]\begin{gathered} y-5=1\cdot x-1\cdot6 \\ y-5=x-6 \\ y-5+5=x-6+5 \\ y=x-1 \end{gathered}[/tex]

The equation for a line parallel to y=x+4 that passes through point (6,5) is

Write a quadratic function in standard form whose graph passes through the given points1. (-1,5), (0,3), (3,9)

Answers

The Standard Form of a Quadratic Function:

[tex]\text{ y = ax}^2\text{ + }bx\text{ + c}[/tex]

Using the given points (-1,5), (0,3), and (3,9)​, let's substitute each point to the equation.

At (-1,5):

[tex]\text{ y = ax}^2\text{ + bx + c }\rightarrow5=a(-1)^2\text{ + b(-1) + c}[/tex][tex]\text{ 5 = a - b + c}[/tex]

At (0,3):

[tex]\text{ y = ax}^2\text{ + bx + c }\rightarrow3=a(0)^2\text{ + b(0) + c}[/tex][tex]\text{ 3 = c}[/tex]

At (3,9):

[tex]\text{ y = ax}^2\text{ + bx + c }\rightarrow9=a(3)^2\text{ + b(3) + c}[/tex][tex]\text{ 9 = 9a + 3b + c}[/tex]

We now get these equations:

5 = a - b + c ; 3 =c; 9 = 9a + 3b + c

Let's determine the value of a, b and c. We get,

Substituting 3 = c to 5 = a - b + c,

[tex]\text{ 5 = a - b + c }\rightarrow\text{ 5 = a - b + 3 }\rightarrow\text{ a - b = 2}[/tex][tex]\text{ b = a - 2}[/tex]

Let's substitute 3 = c and b = a - 2 to 9 = 9a + 3b + c,

[tex]\text{ 9 = 9a + 3b + c }\rightarrow\text{ 9 = 9a + 3(a-2) + 3}[/tex][tex]\text{ 9 = 9a + 3a - 6 + 3 }\rightarrow\text{ 12a = 9 + 6 - 3 }\rightarrow\text{ 12a = 12}[/tex][tex]\text{ a = }\frac{12}{12}\text{ = 1}[/tex]

Since a = 1, let's solve for the value of b which is b = a - 2.

[tex]\text{ b = a - 2 }\rightarrow\text{ b = 1 - 2}[/tex][tex]\text{ b = -1}[/tex]

Since we've identified that a = 1, b = -1 and c = 3, let's substitute the values to the standard form of a quadratic function to be able to make the equation.

[tex]\text{ y = ax}^2\text{ + bx + c }\rightarrow y=(1)x^2\text{ + (-1)x + (3)}[/tex][tex]\text{ y = x}^2\text{ - x + 3}[/tex]

Therefore, the quadratic function in a standard form whose graph passes through the given points (-1,5), (0,3), (3,9)​ is y = x^2 - x + 3.

A club is selling snacks at a track meet. Oranges cost $1 each and protein bars cost $4 each. They sell 100 items and collect 304. Describe what the solution means in the context of the situation. Explain your thinking

Answers

By writing and solving a system of equations, we will see that the club sold 32 oranges and 68 bars.

What the solution means?

Here the solution will be the number of oranges and protein bars sold.

Let's define:

x = number of oranges.

y = number of bars.

We know that they sell 100 items and win a total of $304, then we can write the system of equations:

x + y = 100

x*$1 + y*$4 = $304

Isolating x on the first equation we get:

x = 100 - y

Replacing that in the other equation we get:

(100 - y)*$1 + y*$4 = $304

$100 - y*$1 + y*$4 = $304

y*$3 = $304 - $100 = $204

y = $204/$3 = 68

y = 68

And the value of x is:

x = 100 - y = 100 - 68

x = 32

That is the solution, x = 32 and y = 68.
