Answer:

Non-linear

Step-by-step explanation:

y = 10/x is non-linear!

Because a linear equation is an equation of a straight line, which means the degree of a linear equation must be 0. In this case, the degree of variable y is 1; the degrees of the variables in the equation violate the linear equation definition, which means that the equation is not linear.

On solving the provided question, we can say that the new equation of the line is = (y +6) = 1/2(x-3) => x - 2y = 9

A mathematical equation is a formula that joins two statements and uses the equal symbol (=) to indicate equality. A mathematical statement that establishes the equality of two mathematical expressions is known as an equation in algebra. For instance, in the equation 3x + 5 = 14, the equal sign places the variables 3x + 5 and 14 apart. The relationship between the two sentences on either side of a letter is described by a mathematical formula. Often, there is only one variable, which also serves as the symbol. for instance, 2x – 4 = 2.

coordinates are (3, -6)

the perpendicular equation is y = -2x

so, m. the slope = 1/2

the new equation of the line is = (y +6) = 1/2(x-3)

2y + 12 = x = 3

x - 2y = 9

Answer:

Step-by-step explanation:

To graph the equation 3y = -6x - 12, we can start by finding the x and y intercepts.

The x-intercept is the point where y = 0, so we can substitute 0 for y in the equation:

3y = -6x - 12

3 * 0 = -6x - 12

0 = -6x - 12

12 = -6x

x = -2

So the x-intercept is (-2, 0).

The y-intercept is the point where x = 0, so we can substitute 0 for x in the equation:

3y = -6x - 12

3y = -6 * 0 - 12

3y = -12

y = -4

So the y-intercept is (0, -4).

Now that we have the x and y intercepts, we can plot the points on the graph and draw a line that passes through both points. This line will be the graph of the equation.

In this case, the graph of the equation 3y = -6x - 12 is a downward sloping line that passes through the points (-2, 0) and (0, -4).

The equation to determine the maximum number of bracelets Mr. Gonzales could buy is 29 + 4.50x = 42.50 and the maximum number of bracelets is 3.

According to the question Gonzales has $42.50.

Cost of shirt = $29

Cost of bracelets = $4.50 each.

so, the equation becomes

Total cost = money that Gonzales has.

The cost is $29 + 4.50x, where x is the number of bracelets he can buy.

29 + 4.50x = 42.50

4.50x = 42.50 - 29

x = 13.50/4.50

x = 3

So we have that Mr. Gonzales can buy a total of 3 bracelets.

Answer: The equation is $29 + x$4.50 = $42.50, and the solution is x = 3

Step-by-step explanation:

The data we have is: Gonzales has $42.50. He wants to buy a shirt that costs $29. SOME bracelets that cost $4.50 each.

The equation that we need to solve is: Total cost = money that Gonzales has. The expression to find the cost is $29 + $4.50x

X represents the number of bracelets he can buy. The equation that we need to solve is: $29 + $4.50x = $42.50

To solve it we must isolate the x

$4.50x = $42.50 - $29 = $13.50x = 13.50/4.50 = 3

So we have that Mr. Gonzales can buy a total of 3 bracelets.

Answer:

x = 45

Step-by-step explanation:

the sum of the interior angles of a quadrilateral = 360°

sum the angles and equate to 360

x + 3x + 90 + 90 = 360

4x + 180 = 360 ( subtract 180 from both sides )

4x = 180 ( divide both sides by 4 )

x = 45

Answer:

Step-by-step explanation:

The expression 36 divided by s = 4 can be solved for s by dividing both sides of the equation by 36:

36/s = 4

Dividing both sides of the equation by 4:

s = 36/4 = 9

So, the value of s that makes the equation true is 9. This means that if you divide 36 by 9, the result will be 4.

The probability distribution function of Y is the set of all probabilities P(Y), for all possible values of Y[tex]P(Y) = (C(7, Y) * (12/52)^Y * (40/52)^{(7-Y)} /C(7, 52)[/tex]. Option E is correct.

Let Y be the discrete random variable that counts the number of face cards in a seven-card hand drawn from a standard 52-card deck. The possible values for Y are 0, 1, 2, 3, 4, 5, 6, and 7.

The number of ways to get Y face cards in a seven-card hand is given by the binomial coefficient C(7, Y), where C(7, Y) represents the number of combinations of 7 things taken Y at a time.

The probability of getting Y face cards in a seven-card hand is given by:

[tex]P(Y) = (C(7, Y) * (12/52)^Y * (40/52)^{(7-Y)} /C(7, 52)[/tex]

where [tex](12/52)^Y[/tex] represents the probability of drawing Y face cards and [tex](40/52)^{(7-Y)}[/tex] represents the probability of drawing the remaining 7-Y cards from the 40 non-face cards.

Thus, the probability distribution function of Y is the set of all probabilities P(Y), for all possible values of Y:

[tex]P(Y) = (C(7, Y) * (12/52)^Y * (40/52)^{(7-Y)} /C(7, 52)[/tex]

We can tell that Mike thought the difference would be 72, but it is actually 72.74 by rounding off.

A number is simplified when it is rounded off, preserving its value while moving it closer to the next number.

It is done for whole numbers as well as decimals at various places of hundreds, tens, tenths, etc.

When numbers are rounded off, the important numbers are kept.

To determine how to round a number, look at the next digit in the appropriate position; if it is less than 5, round down, and if it is greater than 5, round up.

So, Mike determined 79 to be 79.44 and 7 to be 6.7, so he determined the difference as follows:

79 - 7 = 72

Actual numbers that vary are:

79.44 - 6.7 = 72.74

Therefore, we can tell that Mike thought the difference would be 72, but it is actually 72.74 by rounding off.

A bone fragment that has 10% of the parent Pb-210 remaining with half-life of Pb-210 is 22 years, the bone fragment is approximately 51 years old.

To determine the age of the bone fragment, you need to calculate the number of half-lives that have elapsed since the bone was formed. The age of the bone can be calculated using the formula:

age = number of half-lives * half-life

To calculate the number of half-lives, you need to determine how much of the original Pb-210 has decayed. If a bone fragment has 10% of the parent Pb-210 remaining, then 90% has decayed.

You can calculate the number of half-lives by taking the natural logarithm of the ratio of the remaining amount of Pb-210 to the original amount:

number of half-lives = ln(0.10) / ln(0.5)

Using the half-life of Pb-210, which is 22 years, you can now calculate the age of the bone fragment:

age = number of half-lives * 22 years

Substituting the values and calculating the number of half-lives and the age of the bone fragment, you get:

number of half-lives = ln(0.10) / ln(0.5) = 2.302

age = number of half-lives * 22 years = 51.064 years

So, the bone fragment is approximately 51 years old.

the circumference of the circle is 19.4568 cm or, rounded to two decimal places, 94.68 cm.

94.68 cm

The formula for circumference of a circle is C = 2πr, where r is the radius of the circle. Therefore, to find the circumference of the circle, we need to first calculate the radius.

The area of the circle is given as A = πr2.

Therefore, we can rearrange this equation to solve for the radius, which is

r = √(A/π)

Plugging in the given area, A = 3.14, we get

r = √(3.14/π) = √(3.14/3.14) = 1

Now, we can use the circumference formula to calculate the circumference, which is

C = 2πr = 2π(1) = 2π × 3.14 = 6.28 × 3.14 = 19.4568

Therefore, the circumference of the circle is 19.4568 cm or, rounded to two decimal places, 94.68 cm.

What is the equation straight line?

The formula for a straight line is generally expressed as Y = mx + c, where m stands for the slope and c for the y-intercept. In geometry, it is the straight-line version of the equation that is most usually utilised. A straight-line's equation can be expressed in a variety of forms, including point-slope form, slope-intercept form, general form, standard form, etc. An infinitely long straight line has two dimensions and is a geometrical object with two ends. The equations for a straight line that are used the most frequently are y = mx + c and axe + by = c. Point-slope, slope-intercept, standard, general, and other forms are more variations.

The given line is y = x/5 +3

the slope is m = 1/5

So the slope of the perpendicular line will be -5

So the equation of line will be y-3 = m1(x-1)+3

y-3 = -5x+5+3

y = -5x +11

Hence the equation for the line will be y = -5x +11.

1 4/5 bags of dog food will last the LPS for approximately 8 and 3/10 days, or 8.3 days.

The Logan pet store uses 9/10 of a bag of dog food every day, which means they need 9/10 * 1 bag = 9/10 bags of dog food per day. To determine how many days 1 4/5 bags of dog food will last,

we need to divide the total amount of dog food by the amount used per day: 1 4/5 bags / (9/10 bags/day) = (9/10)*(18/5) / (9/10) = 18/5 days. Therefore, 1 4/5 bags of dog food will last for 18/5 days.

One 4/5 bags of dog food will last the Logan Pet Store (LPS) for approximately 8 and 3/10 days. This is because if the LPS uses 9/10 of a bag of dog food every day, then they are using 9/10 * 5/5 = 9/10 bags of dog food per day. If we divide 1 4/5 bags of dog food by 9/10 of a bag per day, we get (1 4/5) / (9/10) = (18/5) / (9/10) = 18/5 * 10/9 = 20/9 days.

None. The discriminant of the quadratic equation is [tex]b^{2}[/tex]-4ac = [tex]11^{2}[/tex] - 4(1)(18) = 121 - 72 = 49, which is not a perfect square.

A perfect square is a number that can be expressed as the product of two equal integers. For example, 9 is a perfect square because it can be written as 3 x 3.

The zeros of this quadratic function can be found by setting the equation equal to 0 and solving for x.

0 = [tex]x^{2}[/tex] + 11x + 18

To solve for x, we can use the quadratic formula:

x = [-b ± √([tex]b^{2}[/tex] - 4ac)]/2a

Substituting in our values from the equation above, we get:

x = [-11 ± √([tex]11^{2}[/tex] - 4(1)(18))]/2(1)

x = [-11 ± √(-63)]/2

Since the square root of a negative number is not a real number, there are no zeros.

Therefore, the answer is None.
