Which of the following is equivalent to 7-2(x + 2) <-4 - 3(1 - x)?

Answer:

12 toppings

Step-by-step explanation:

To do this, we need to write an equation for each place, and then, equal both equations to solve for this.

Let's call "y" the price of the pizza, and "x" the number of toppings.

At Vincents, pizza costs 6.75 + 0.75 for each topping, so the equation here would be:

y = 6.75 + 0.75x  (1)

Now, at italian pizza, a pizza costs 6.15 + 0.80 per topping, so the equation:

y = 6.15 + 0.80x  (2)

Now, we don't need to know the actual price of the pizza, we only want to know how many toppings we need to add on both places, so the pizza has the same price. We have both equations, it's time to equal both of them:

Equalling (1) and (2) we have:

6.75 + 0.75x = 6.15 + 0.80x

Now, let's solve for x:

6.75 - 6.15 = 0.80x - 0.75x

0.6 = 0.05x

x = 0.6 / 0.05

x = 12

So the number of toppings to include in the pizza so the price is the same for both places, will have to be 12 toppings.

Answer:

12 toppings and the prize will be the same.

Step-by-step explanation:

Let

number of toppings = a

Medium pizza at Vincent's

cost  = 6.75 + 0.75a

Medium pizza at Original Italian Pizza

cost  = 6.15 + 0.80a

For the cost to be the same

6.75 + 0.75a = 6.15 + 0.80a

collect like terms

6.75 - 6.15 = 0.80a - 0.75a

0.6  = 0.05a

divide both sides by 0.05

a = 0.6/0.05

a = 12  

12 toppings and the prize will be the same.

Answer:

100 degrees

Step-by-step explanation:

Answer:

- number of hours on video games and test scores

- average running speed and total race time

- outside temperature and amount of a heating bill

Step-by-step explanation:

1. number of hours on video games and test scores (negative correlation - as you spend more hours on video games, test scores might decrease)

2. speed of a car and minimum stopping distance (positive correlation - as the distance to the next stop increases, the speed of the car should increase)

3. average running speed and total race time (negative correlation - as you run for longer, your speed should decrease)

4. adult’s head circumference and age (positive correlation - as your age increases, your head size increases, too)

5. outside temperature and amount of a heating bill (negative correlation - as temperature increases, the heating bill decreases)

The two options with negative correlations are:

"Number of hours on video games and test scores" and "Outside temperature and amount of a heating bill"

A relation between two variables, x and y, has a negative correlation when if one variable increases, the other decreases.

From the options, the ones that can have a negative correlation are:

Number of hours on video games and test scores: Here as the number of hours that you play video games increases, it is possible that your test scores decrease, so we have a negative correlation.

Outside temperature and amount of a heating bill: As the outside temperature decreases, the amount that you pay in heating increases, so again, we have a negative correlation.

Step-by-step explanation:

    The other tables don't increase or decrease by only one number.  I'm pretty sure it's B. If it isn't, my apologies.

The required linear function is given by-
x  = 3   4   5   6  
y  = 6   5   4    3
Option 2 is correct.

From the option of tables the option that shows linear function is to be chosen.

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

Options 1), 3), and 4) can be omitted because the relation between the column of the table is not a linear function and is irrelevant to each other. While option 2) contains the table that shows a linear relationship by the following expression,

y = -x + 9

The cross section of the rectangular prism is parallel to the base.

So, the length and width is congruent to the base. So, same length and width

Answer:

125

Step-by-step explanation:

Say prism A is a cube, and all the sides are x, then the volume of prism A is [tex]x^3[/tex].

If you multiply each side by 5 (prism B), then each side is 5x, so the volume of prism B is [tex]125x^3[/tex], which is 125 times more than [tex]x^3[/tex].

Answer:

We need the picture.

Step-by-step explanation:

Unless the data is skewed (which means there is outliers) then you use mean as the most accurate. If you have a skewed graph or outliers then mean would mislead you to believe prices are higher (if you have high outliers) or low (if you have low outliers). Median is typically very accurate. Mode may be inaccurate if you have a lot of prices in a really high or low value.

Answer:

1) A profit of Rs 250 is made.

3) 14/15 kg

4) 15/28

Step-by-step explanation:

1) A profit of Rs.10 per bag of oranges and a loss of Rs.5 per bag of grapes sold. The total profit/loss from selling 200 bags of oranges and 350 bags of grapes is:

total profit/loss = 200 (10) - 5(350) = 2000 - 1750 = Rs 250

A profit of Rs 250 is made.

Step-by-step explanation:

Hi, to answer this we have to equal both equations given and solve for x.

2/3x+2 = 4/3x-6

Solving for x:

2/3x-4/3x= -6-2

-2/3x = -8

x = -8/ (-2/3)

In conclusion, when the value of x is equal to 12, both expressions will have the same value.

Order of the matrices must be the same in order to add them up

Adding matrices mean adding corresponding elements together

Order of matrix is 4 rows and 1 column

Answer:

4 x 1  ( 4 rows and one column)

Step-by-step explanation:

Recall the definition for order of a matrix: The number of rows times the number of columns.

So, in this case, we are adding matrix A which is 4 rows and 1 column to matrix B which is also of 4 rows and one column, obtaining a third matrix that has also 4 rows and one column:

[tex]\left[\begin{array}{cccc}-9\\0\\3\\-1\end{array}\right] +\left[\begin{array}{cccc}0\\4\\-6\\2\end{array}\right] =\left[\begin{array}{cccc}-9\\4\\-3\\1\end{array}\right][/tex]

The resultant A + B is also of 4 rows and one column

Answer:

Mean = 11.8

Median = 11

Step-by-step explanation:

Here we are asked to calculate the median and the mean for these set of numbers

Let’s start with the mean

The mean refers to the average, we simply add all the numbers together and divide by their count.

That would be;

Arithmetic mean = (10+ 5 + 18 + 9 + 17 + 12)/6 = 71/6 = 11.833 which is 11.8 to the nearest tenth

To get the median, what we do is to first rearrange the values we have from the lower to the highest.

That would be;

5,9,10,12,,17,18

Looking at the numbers after rearranging, the two middle numbers we have are 10 and 12.

So we add these together divide by 2.

That would be (10+12)/2 = 22/2 = 11

Answer:

The volume of the pyramid is 165.4 inches^3

Step-by-step explanation:

In this question, we are asked to calculate the volume of the pyramid with a square base and also with the given height.

To find the area of this pyramid, what we need to do is to multiply the area of the base by the height of the pyramid

From the question, the area of the square base is 11.9 in^2 while the height of the pyramid is 13.9 in

Thus the volume here is simply 11.9 * 13.9 = 165.41 which to the nearest tenth of cubic inch is 165.4 inch^3

5 is the answer mate

Step-by-step explanation:

Answer:

the answer is A

Step-by-step explanation:

if u see, to get Y2 on its own u have to first multiply x2-x1 on both sides

m(x2-x1)=y2-y1

and then to get Y2 alone u need to add Y1 to both sides

m(x2-x1)+y1=y2

The following equations is equivalent to the slope formula A.

We have given that,

consider the formula for slope between two coordinate points, m, shown below.

[tex]m=y_2-y_1/x_2-x_1[/tex]

[tex]m=y_2-y_1/x_2-x_1[/tex]

Where m is the slope and [tex]y_1[/tex] and [tex]y_2[/tex] and [tex]x_1[/tex] and [tex]x_2[/tex] are coordinates of the axis.

if u see, to get [tex]Y_2[/tex] on its own u have to first multiply [tex]x_2-x_1[/tex] on both sides

[tex]m(x_2-x_1)=y_2-y_1[/tex]

and then to get Y2 alone u need to add Y1 to both sides

[tex]m(x_2-x_1)+y_1=y_2[/tex]
