Which of the following points is a solution to y ≤ −2x + 3?
above; y = 2x − 2
below; y = 2x − 2
above; y = −2x + 2
below; y = −2x + 2
Answers
Answer:
d; below; y = −2x + 2
Step-by-step explanation:
the equality ≤ means left to right that y is equal or less than. We see that 2 is equal or less than 3.
We check the resulting equation also and see that if we +3 it = 1 and if we +2 it equals 0 so we know +2 in answer format can be less than also. But with questions we are measuring the units and +2 is less than +3.
Answer:
B (1,0) hope this helps :)

Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?
Answers
Step-by-step explanation:
Let's assume the amount Mackey initially invested in the 6% account is x dollars.
According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.
The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.
The total interest earned in the year is given as $737.50, so we can set up the equation:
0.06x + 0.085(x + $1000) = $737.50
Simplifying the equation:
0.06x + 0.085x + 0.085($1000) = $737.50
Combining like terms:
0.145x + $85 = $737.50
Subtracting $85 from both sides:
0.145x = $737.50 - $85
0.145x = $652.50
Dividing both sides by 0.145:
x = $652.50 / 0.145
x ≈ $4500
Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.
$4500
$4500
$4500
$4500

Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²

We can then use our new found information for w+w+x+x = 24. We know that W = 5, so: 5+5+x+x = 24, and then 10+2x (because there were two Xs (if it was x+x+x, it would be 3x)) so, 10+2x=24, we can subtract 10 from both sides to get 2x by itself:
2x=24-10,
2x=14,
Then to get X by itself, we can divide by 2 on both sides:
2x/2 = 14/2

One package of blueberries costs $ 5 . How many packages of blueberries can you buy for $ 15 ? Is this relationship proportional ? Explain your reasoning .
Answers
Divide the total amount of money you have by the cost of one package of blueberries.
If one package of blueberries is $5, and you have $15, divide 15 by 5
15 ÷ 5 = 3
Answer: (pt.1)You can buy 3 packages of blueberries with $15 dollars.
--
In a proportional relationship, the ratios of the x and y variables are equivalent.
To find out if this relationship is proportional, take two of the points and convert them to fractions (x over y).
(1, 5) & (3, 15) ⇒ \(\frac{1}{5}\) & \(\frac{3}{15}\)
Divide the numerators and denominators by each other. If they both equal the same number, the relationship is proportional.
3 ÷ 1 = 3 ,,, 15 ÷ 5 = 3
Answer: (pt. 2)Yes, the relationship is proportional.

The post office charges $0.70 to send one letter, and there is a flat fee of $1.50.
How to determine the the flat fee (F) charged by the post officeTo find the cost of sending one letter, we need to determine the flat fee charged by the post office.
Let's denote the flat fee as 'F' and the cost per letter as 'C'.
From the given information, we can set up the following equations:
Equation 1: F + 35C = 26
Equation 2: F + 18C = 14.10
We can solve this system of equations to find the values of F and C.
First, we subtract Equation 2 from Equation 1 to eliminate F:
(F + 35C) - (F + 18C) = 26 - 14.10
17C = 11.90
Now, we divide both sides of the equation by 17 to solve for C:
C = 11.90 / 17
C ≈ 0.70
Therefore, the cost to send one letter (C) is approximately $0.70.
To find the flat fee (F), we can substitute the value of C into either Equation 1 or Equation 2. Let's use Equation 1:
F + 35(0.70) = 26
F + 24.50 = 26
F = 26 - 24.50
F = 1.50
Therefore, the flat fee (F) charged by the post office is $1.50.

cassie is placing stickers on a page that is 12 inches long and 8 inches wide the sticker are 3 inches long and 2 inches wide
Answers
Answer:
To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.
Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).
Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).
To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.
Step-by-step explanation:
Answer:
16
Step-by-step explanation:
First, find out how much stickers you can put on the long side:
12/3 = 4
Next, find out how much stickers you can put on the wide side:
8/2 = 4
Lastly, calculate them together:
4x4=16
So the answer is 16.
1. Is the average change in population the same now as it was 50 years ago? Explain your answer.
2. Reflect on the interpretation of your data.
3. What should you consider when comparing population growth (or decline) over different intervals of time? Hint: What factors influence population growth or decline? Explain fully and provide examples where needed.
Answers
1. The average change in population is not the same now as it was 50 years ago. The population growth rate can vary greatly from year to year and decade to decade, and is influenced by a variety of factors such as birth and death rates, immigration, and emigration. Therefore, it is important to analyze the specific data for each time period to determine the average change in population.
2. When interpreting data on population growth or decline, it is important to consider the factors that influence population change and to analyze the data in the context of the specific time period being studied. It is also important to consider the accuracy and reliability of the data source, as well as any potential biases or limitations in the data.
3. When comparing population growth or decline over different intervals of time, it is important to consider a range of factors that can influence population change, such as birth and death rates, migration patterns, economic and environmental conditions, and government policies. For example, population growth rates in a country may be influenced by changes in healthcare access or advancements in technology that reduce infant mortality rates or increase life expectancy. In addition, migration patterns can greatly impact population growth rates, as some regions may experience large influxes of immigrants or emigrants at different periods in time. When comparing population data over different intervals of time, it is important to take into account these and other factors that may contribute to population growth or decline.

Margo is wrapping a box that is 7 inches long, 10 inches wide, and 4 inches high. How much wrapping paper will she need to cover the entire box?
Answers
She will need to cover six sides of the box. To calculate the surface area of the box, you'll need to add the area of each side. The formula for surface area is: 2lw + 2lh + 2wh. Plugging in the dimensions of the box, we get:
2(7 x 10) + 2(7 x 4) + 2(10 x 4) = 140 + 56 + 80 = 276
So, she will need 276 square inches of wrapping paper. But since she doesn't need to wrap the bottom of the box, we subtract one of the sides, which gives us a total of 268 square inches of wrapping paper.
To calculate the surface area of the box, you need to add the area of all six sides. The area of each side can be found by multiplying the length by the width.
- The area of the front and back sides is 7 x 4 = 28 square inches each.
- The area of the top and bottom sides is 10 x 4 = 40 square inches each.
- The area of the two side sides is 7 x 10 = 70 square inches each.
So, the total surface area of the box is 2(28) + 2(40) + 2(70) = 56 + 80 + 140 = 276 square inches.
Therefore, Margo will need at least 276 square inches of wrapping paper to cover the entire box.
Answer:280 in
Step-by-step explanation: First we multiply the length by the width and that would be 7 by 10 and we would get 70. Next we multiply the height by the total of (l x w), so 4 x 70 would be 280. Margo needs a total of 280 inches of wrapping paper to cover the entire box. Hope this helps! :)

Answer: The correct answer is:
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
