Which number line represents all of the values of x for the equation x2 = 25?

Answers

Answer:

x = 5 and x = -5

Step-by-step explanation:

Given x^2 = 25, we take the square root of both sides.  The two solutions are x = 5 and x = -5

Final answer:

The values for x in the equation x2 = 25 are 5 and -5. These solutions are represented on a number line at points 5 and -5.

Explanation:

The equation x2 = 25 can be solved by taking the square root of both sides of the equation. When we take the square root of a number, we get two possibilities: a positive and a negative value, since squaring a number always results in a positive number. Therefore, the values for x in the given equation would be x = 5 and x = -5.

On a number line, these points would be represented at the 5 and -5 positions. Therefore the number line that represents all the values of x for the equation x2 = 25 is the one that includes both -5 and 5. Keep in mind that no other numbers would satisfy the equation x2 = 25.

Answers

Final answer:

The range of the data set is 67 pounds.

Explanation:

The range of a data set is the difference between the maximum and minimum values. In this case, the weights of the 7 dogs are 66, 8, 12, 74, 36, 66, and 7 pounds. To find the range, we subtract the smallest value (7) from the largest value (74):



Range = 74 - 7 = 67

Final answer:

Ben goes to the grocery store at a rate of 7 times a week. To find out how many times he goes in 17 weeks, you multiply 7 by 17, which equals 119. Therefore, Ben is expected to go to the grocery store 119 times in 17 weeks.

Explanation:

To calculate how many times Ben goes to the grocery store in 17 weeks, given that he goes at a rate of 7 times a week, we need to multiply the number of weeks by the frequency of his visits per week. The calculation is as follows:

Multiply the number of visits per week by the number of weeks: 7 visits/week  imes 17 weeks. Perform the multiplication: 7  imes 17 = 119. Therefore, Ben is expected to go to the grocery store 119 times in 17 weeks.

3 Fred is making a fruit salad. The ratio
of cups of peaches to cups of cherries
is 2 to 3. How many cups of peaches
will Fred need to make 60 cups of
fruit salad?​

Answers

Answer: 24 cups.

Step-by-step explanation:

Let be "x" the amount of cups of peaches  that Fred will need to make 60 cups of  fruit salad.

According to the information given in the exercise, you know that the ratio of cups of peaches to cups of cherries is the one shown below:

[tex]2:3[/tex]

Which can also be written as a fraction:

[tex]\frac{2}{3}[/tex]

Then, if he uses 2 cups of peaches and 3 cups of cherries, he will get 5 cups of fruit salad.

Knowing the above, you can set up the following proportion:

[tex]\frac{2}{5}=\frac{x}{60}[/tex]

Now you must solve for "x" in order to find its value. This is:

[tex](60)(\frac{2}{5})=x\\\\x=24[/tex]

What is an equation of a line which passes through (6,9) and is perpendicular to the line whose equation is 4x − 6y = 15?

1) y−9=−2(x−6)
2
2) y−9= 3(x−6)
3
3) y+9=−2(x+6)
4) y+9=23(x+6)

Answers

Given:

The equation of the line passes through the point (6,9) and is perpendicular to the line whose equation is [tex]4 x-6 y=15[/tex]

We need to determine the equation of the line.

Slope:

Let us convert the equation to slope - intercept form.

[tex]-6 y=15-4x[/tex]

   [tex]y=\frac{2}{3}x-\frac{5}{2}[/tex]

From the above equation, the slope is [tex]m_1=\frac{2}{3}[/tex]

Since, the lines  are perpendicular, the slope of the line can be determined using the formula,

[tex]m_1 \cdot m_2=-1[/tex]

  [tex]\frac{2}{3} \cdot m_2=-1[/tex]

      [tex]m_2=-\frac{3}{2}[/tex]

Therefore, the slope of the equation is [tex]m=-\frac{3}{2}[/tex]

Equation of the line:

The equation of the line can be determined using the formula,

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

Substituting the point (6,9) and the slope [tex]m=-\frac{3}{2}[/tex] in the above formula, we get;

[tex]y-9=-\frac{3}{2}(x-6)[/tex]

Simplifying the terms, we get;

[tex]2(y-9)=-3(x-6)[/tex]

[tex]2y-18=-3x+18[/tex]

[tex]3x+2y=36[/tex]

Thus, the equation of the line is [tex]3x+2y=36[/tex]

Final answer:

The equation of a line that is perpendicular to the line 4x - 6y = 15 and passes through the point (6,9) is 3x + 2y = 36. This is because the slope of the new line is the negative reciprocal of the slope of the given line, and the line passes through the given point (6,9).

Explanation:

The subject of this question is mathematics, specifically in the topic of linear equations. To find the equation of a line that is perpendicular to a given line and passes through a certain point, we first need to find the slope of the given line. The standard form of the equation of a line is Ax + By = C. The given line is 4x - 6y = 15. We can find its slope by taking the negative reciprocal of the coefficient of x (A) over the coefficient of y (B), so the slope of the given line is -4/-6 = 2/3. Since we want a line that is perpendicular to the given line, the slope of the line we are looking for would be the negative reciprocal of the slope of the given line, which would be -3/2, because perpendicular lines have slopes that are negative reciprocals of each other. Using the point-slope form of a line, y - y1 = m(x - x1), where m is the slope and (x1, y1) is the given point, the equation of the line we are looking for is y - 9 = -3/2(x - 6), which simplifies to 2y - 18 = -3x + 18 and further simplifies to 3x + 2y = 36. So the answer is none of the given options.

if the cost of goods sold was $42,000 the income from sales was $86,000 and the expenses were $12,000 find gross profit and net profit

Answers

Gross profit is $44,000 and Net profit is $32,000

Step-by-step explanation:

Given :

cost of goods sold = $42,000The income or revenue = $86,000expenses = $12,000

Gross profit :

Gross Profit = Total income - Cost of goods sold

⇒ $86,000 - $42,000

⇒ $44,000

Gross profit is $44,000

Net profit :

Net profit = Gross profit – Total Expenses

⇒ $44,000 - $12,000

⇒ $32,000

Net profit is $32,000

Makoto's summer job is mowing and edging lawns. He charges $20 to mow a lawn and $10 to edge a lawn. Makoto earned $180 mowing some lawns and edging 4 lawns. How many lawns did he mow?

Answers

Answer:

7

Step-by-step explanation:

to edge a lawn =10.he edged 4 lawn =10multiplied by 4=40

2nd. total -40=180-40=140

3rd. when he mows 1 lawn he is paid 20 what about when he is paid 140=140 divided by 20 =7

Makoto mowed 7 lawns to earn $180.

Let's denote the number of lawns Makoto mowed as m. Since he edged 4 lawns, that part of the income is 4 times $10, which sums up to $40. The total income from mowing is then $20 times the number of lawns he mowed, which is m. The equation representing Makoto's earnings is:

20m + 40 = 180

Subtracting 40 from both sides gives us:

20m = 140

Dividing both sides by 20 to solve for m gives us:

m = 7

        or

5x + 22y - 21 = 0

Step-by-step explanation:

evaluate    7 = 5x+y÷3-3y​

7 = [5x + y]/[3-3y]

Don't forget 7 can also be expressed in form 7/1,

so the step to follow is using a cross multiplication technique.

we have ;

5x + y = 7(3 - 3y)

5x + y = 21 - 21y

Collect the like terms (note when the negative sign crosses over the equal to sign it changes to positive and the same thing applies to positive sign it changes to negative respectively.)

5x + y  + 21y = 21

5x + 22y = 21

Find a linear function that models the data in the table.

f(x)= *blank* x + *blank*

Answers

Final Answer:

The linear function that models the data in the table is [tex]\( f(x) = 2x + 3 \)[/tex].

Explanation:

To find the linear function, we need two key pieces of information: the slope mn and the y-intercept b. In the given function f(x) = 2x + 3, the coefficient of x (2) represents the slope, and the constant term (3) represents the y-intercept.

The slope m indicates the rate at which the function is changing, and in this case, it is 2. This means that for every unit increase in x, y increases by 2 units. The y-intercept b is the value of y when x is zero, which is 3 in this case. Therefore, the linear function f(x) = 2x + 3 accurately models the relationship between x and y in the given dat x in a linear manner.

In summary, the general form of a linear function is [tex]\(f(x) = mx + b\)[/tex], where m is the slope and b is the y-intercept. The values of m and b can be determined from the data or information provided.

The linear function that models the data in the table is [tex]\(f(x) = \frac{13}{7}x + 1\)[/tex], where x represents the input and f(x) the output.

To find a linear function that models the data in the table, we can use the slope-intercept form of a linear equation: f(x) = mx + b, where m is the slope and b is the y-intercept.

Let's find the slope (m) first using the given data points (-4, -6) and (3, 7):

[tex]\[m = \frac{\text{change in } y}{\text{change in } x} = \frac{7 - (-6)}{3 - (-4)} = \frac{13}{7}.\][/tex]

Now that we have the slope, we can use any point from the table to find the y-intercept (b). Let's use the point (0, 1):

[tex]\[1 = m(0) + b \implies b = 1.\][/tex]

Now, we can write the linear function:

[tex]\[f(x) = \frac{13}{7}x + 1.\][/tex]

So, the linear function that models the data in the table is [tex]\(f(x) = \frac{13}{7}x + 1\)[/tex].

a card is randomly chosen from a standard deck of cards. Find each probability.

Answers

Answer: The probability is 1/52 or .0192.

Step-by-step explanation:

A standard deck of cards has 52 so the probability of picking 1 card would be 1/52.

(a) The probability of drawing a spade is 1/4.

(b) The probability of drawing a face card (jack, queen, or king) is 3/13.

(c) The probability of drawing a red card is 1/2.

(d) The probability of drawing a card that is not an ace is 12/13.

What is probability?

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

Probability = Number of required events / Total number of outcomes.

Example:

The probability of getting a head in tossing a coin.

P(H) = 1/2

We have,

(a) The probability of drawing a spade.

There are 13 spades in a standard deck of 52 cards, so the probability of drawing a spade is:

P(spade) = 13/52 = 1/4

(b) The probability of drawing a face card (jack, queen, or king).

There are 12 face cards (4 jacks, 4 queens, and 4 kings) in a standard deck of 52 cards, so the probability of drawing a face card is:

P(face card) = 12/52 = 3/13

(c) The probability of drawing a red card.

There are 26 red cards (13 hearts and 13 diamonds) in a standard deck of 52 cards, so the probability of drawing a red card is:

P(red card) = 26/52 = 1/2

(d) The probability of drawing a card that is not an ace.

There are 48 cards that are not aces in a standard deck of 52 cards (there are 4 aces), so the probability of drawing a card that is not an ace is:

P(not ace) = 48/52 = 12/13

Thus,

(a) The probability of drawing a spade is 1/4.

(b) The probability of drawing a face card (jack, queen, or king) is 3/13.

(c) The probability of drawing a red card is 1/2.

(d) The probability of drawing a card that is not an ace is 12/13.

Let x represent the cost of one package of tulip bulbs.

Let y represent the cost of one bag of daffodil bulbs.

Ava bought 6 packages of tulip bulbs and 12 bags of daffodil bulbs for a total of $198. This means that

6x + 12y = 198- - - - - - - - - - - - -1

Grace spent $254 buying 14 packages of tulip bulbs and 12 bags of daffodil bulbs. This means that

14x + 12y = 254- - - - - - - - - - - - 2

Subtracting equation 2 from equation 1, it becomes

- 8x = - 56

x = - 56/-8

x = 7

Substituting x = 7 into equation 1, it becomes

6 × 7 + 12y = 198

42 + 12y = 198

12y = 198 - 42

12y = 156

y = 156/12

The student is asking how to divide the total cost of a pizza and garlic bread, which is $15.33, evenly among three people. To calculate this, we can use simple division.

Here is the step-by-step calculation:

First, identify the total cost of the food: $15.33.

Next, determine the number of people sharing the cost, which is three.

Divide the total cost by the number of people: $15.33 ÷ 3 = $5.11.

Therefore, each person should pay $5.11 to equally split the cost of the pizza and garlic bread.
