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

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?
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

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.

Step-by-step explanation:
1/3(v-2) < v
Multiply both sides by 3(from 1/3) to equalize both sides.
This is equal to:
v-2 < 3v
Simplify equation:
v-2 < 3v =
-2 < 3v - v =
-2 < 2v
-1 < v
Swap sides:
v > -1
Therefore v is greater than -1.
Answer:
v > -1
Step-by-step explanation:
Simplify the left side.
Apply the distributive property.
13v+13⋅−2<v
Combine 13 and v
v3+13⋅−2<v
Combine 13 and −2
v3+−23<v
Move the negative in front of the fraction.
v3−23<v
Move all terms containing v to the left side of the inequality.
Subtract v from both sides of the inequality.
v3−23−v<0
Simplify the left side of the inequality.
−2(v+1)3<0
Multiply each term in −2(v+1)3<0 by −1
2(v+1)3>0
Multiply both sides of the equation by 3
2(v+1)>0⋅(3)
and again Simplify the left side.
Apply the distributive property.
2v+2⋅1>0⋅(3)
Multiply 2 by 1
2v+2>0⋅(3)
Multiply 0 by 3
2v+2>0
Subtract 2 from both sides of the inequality.
2v>−2
Divide each term by 2 and simplify.
Getting the conclusion where V is greater than 1
v>−1

evaluate the following 7 = 5x+y÷3-3y
Answer:
5x + 22y = 21
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
5x + 22y - 21 = 0

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

Find a linear function that models the data in the table.
f(x)= *blank* x + *blank*
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].

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
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 = $12,000Gross 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
Ariana and two friends decide to split a pizza and garlic bread. If the total cost for the food is $15.33, how much should each person pay?
Answer: $7.665 each, approximately $7.67 each
Step-by-step explanation:
If cost is $15.33
To be sharedby two friends will be the cost/2
15.33/2= $7.665 each
Each person should pay $5.11 to equally split the total cost of the pizza and garlic bread, which is $15.33.
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.
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)
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]
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.

The equivalent choices to the given quotient [tex]\(\frac{\sqrt{12}}{\sqrt{6}}\)[/tex] are A [tex](\(\sqrt{2}\))[/tex] and C [tex](\(\frac{\sqrt{4}}{\sqrt{2}}\))[/tex].
The question shows a math problem asking which choices are equivalent to the given quotient:
[tex]\[ \frac{\sqrt{12}}{\sqrt{6}} \][/tex]
We'll solve this step by step:
1. Simplify the square roots by factoring out squares:
[tex]\[ \sqrt{12} = \sqrt{4 \cdot 3} = \sqrt{4} \cdot \sqrt{3} = 2\sqrt{3} \][/tex]
[tex]\[ \sqrt{6} = \sqrt{2 \cdot 3} = \sqrt{2} \cdot \sqrt{3} \][/tex]
2. Write the original quotient with the simplified square roots:
[tex]\[ \frac{\sqrt{12}}{\sqrt{6}} = \frac{2\sqrt{3}}{\sqrt{2} \cdot \sqrt{3}} \][/tex]
3. Cancel out the common terms:
[tex]\[ \frac{2\sqrt{3}}{\sqrt{2} \cdot \sqrt{3}} = \frac{2}{\sqrt{2}} \][/tex]
4. Rationalize the denominator by multiplying the numerator and denominator by [tex]\(\sqrt{2}\)[/tex]:
[tex]\[ \frac{2}{\sqrt{2}} \cdot \frac{\sqrt{2}}{\sqrt{2}} = \frac{2\sqrt{2}}{2} \][/tex]
5. Simplify the fraction:
[tex]\[ \frac{2\sqrt{2}}{2} = \sqrt{2} \][/tex]
So the simplified quotient is [tex]\(\sqrt{2}\)[/tex]. Now let's check the options in the image to see which ones are equivalent to [tex]\(\sqrt{2}\)[/tex]:
A. [tex]\(\sqrt{2}\)[/tex] - This is the correct simplified form of the given quotient.

C. [tex]\(\frac{\sqrt{4}}{\sqrt{2}}\)[/tex] - Since [tex]\(\sqrt{4} = 2\)[/tex], this simplifies to [tex]\(\frac{2}{\sqrt{2}}\)[/tex], which after rationalization becomes [tex]\(\sqrt{2}\)[/tex], so this is also correct.
D. [tex]\(\frac{2}{\sqrt{3}}\)[/tex] - This is incorrect because it does not simplify to [tex]\(\sqrt{2}\)[/tex].
E. [tex]\(\frac{\sqrt{6}}{\sqrt{2}}\)[/tex] - Since [tex]\(\sqrt{6} = \sqrt{2 \cdot 3}\)[/tex], this simplifies to [tex]\(\sqrt{3}\)[/tex], which is incorrect.
F. [tex]\(\frac{\sqrt{6}}{2}\)[/tex] - This does not simplify to [tex]\(\sqrt{2}\)[/tex] and is therefore incorrect.
The correct answer choices are A and C, which are both equivalent to [tex]\(\sqrt{2}\)[/tex].
