Rewrite the following equations in the form ax + by = c, where A is a positive integer.
y = x + 9

y = -6x - 5

y = 2/3x + 1​

The point of maximum curvature of the curve y = 9 ln(x) occurs when the second derivative of the curve is equal to zero, which is when x = e. At this point, the curvature of the curve is equal to k(x) = 9/e^2.

Infinity is a concept used to describe something that is limitless or without end. It is typically used to describe a quantity, such as an infinite number of objects or an infinite amount of time. It is also used to describe the concept of something that is boundless or has no boundaries. Infinity is an abstract concept and is not considered a number or a measurement.

As x rightarrow infinity, the value of k(x) approaches zero, because the second derivative of the curve approaches zero. Therefore, k(x) approaches zero as x rightarrow infinity.

Step-by-step explanation: The slope is -5/4 and the y intercept is -1

to get the slope of any straight line, we simply need two points off of it, let's use those two in the picture below, keeping in mind that the y-intersect is when the graph intersects the y-axis, so

There is a 1/2 probability that both spinners will produce an odd number.

The probability is equal to the variety of possible outcomes.

The total number of outcomes that could occur.

For instance, there is only one way to receive a head and there are a total of two possible outcomes, hence the probability of flipping a coin and getting heads is 1 in 2. (a head or tail). P(heads) = 12 is what we write.

So, assume that:

Both the spinners have 1 positive number and 1 odd number.

Probability formula:

P(E) = Favourable events/Total events

Now, calculate as follows:

P(E) = Favourable events/Total events

P(E) = 2/4

P(E) = 1/2

Therefore, there is a 1/2 probability that both spinners will produce an odd number.

Given that there is a charge for up to 175 calls, Rs 200.

And each subsequent call will cost Rs 1.

Additionally, there are 13% VAT and 10% TSC.

Taxes total 10 + 13 = 23 %.

12 tons of gravel has been used for the driveway.

Weight of first load = 7 tons

Weight of second load = 8000 pounds

There are 2000 pounds (lb) in one US customary ton (t). Both tons and pounds are measurements of mass/weight in the US customary and imperial systems of measurement. However, the definitions of the ton vary in both systems. For example, there are 2240 pounds in an imperial ton, and 2204.6226 pounds in a metric ton.

The US ton is mostly used in the United States and Canada. The imperial ton was mostly used in the UK, and still is to a degree, but since the UK began the process of metrication, the metric ton is also used in the UK.

Convert pounds to tons:

1 pound = 0.0005 ton

8000 pounds = 4 ton

Then,

Weight of second load = 4 ton

Total weight of the gravel, in tons = Weight of first load + Weight of second load

= 8 tons + 4 tons

= 12 tons

Thus, 12 tons of gravel has been used for the driveway.

Henry's trumpet which is made of an alloy brass contains 9.6 ounces of zinc.

Brass is an alloy created using 80% copper and 20% zinc, which means that for every 100% of the alloy, 80% is copper and 20% is zinc.

If henry's trumpet contains 48 ounces of copper, we can use the proportion of copper and zinc in the alloy to find the number of ounces of zinc.

First, we can convert the percentage of zinc to a decimal by dividing by 100: 20% = 0.20

Next, we can set up an equation using the proportion of zinc in the alloy to the number of ounces of zinc in the trumpet:

0.20 = x/48 ounces of zinc

To solve for x, we can multiply both sides of the equation by 48:

0.20 * 48 = x

x = 9.6 ounces of zinc

So, Henry's trumpet contains 9.6 ounces of zinc.

Answer:

A. We can write a function to represent the cost of each quote using the information provided.

For Decks and More:

C(h) = 1800 + 70h

Where C is the cost and h is the number of hours of labor.

For Just Decks:

C(h) = 2000 + 50h

Where C is the cost and h is the number of hours of labor.

B. To determine which company Aaron should use, we need to substitute the estimated number of hours into the functions for both companies and compare the total costs.

For Decks and More:

C(18) = 1800 + 70(18) = 1800 + 1260 = 3060

For Just Decks:

C(18) = 2000 + 50(18) = 2000 + 900 = 2900

Since Just Decks quote is cheaper, Aaron should use Just Decks.

Answer:

In triangle GHJ, if m angle H = 110 and m angle J = 40, then m angle G = 180 - (110 + 40) = 30. Since angle I is the angle bisector of angle GHJ, the ratio of the length of side HI to the length of side HJ is equal to the ratio of the length of side GI to the length of side GJ.

Since the longest side of a triangle is opposite to the largest angle, the longest side of triangle HIJ is GJ.

The common difference is 4. To find it, you subtract the first two terms (5 and 9) to get 4. You can then use this answer to find the common difference in the sequence by subtracting each consecutive term. For example, 9-5=4, then 13-9=4, and so on.

The common difference is an important part of any arithmetic sequence. It is the number that is added to each term in the sequence to generate the next term. For example, the first two terms of the sequence are 5 and 9. The common difference of 4 is added to the first term (5) to get the second term (9). The common difference is then added to the second term (9) to get the third term (13), and so on. This is how the sequence is generated.  

The common difference is an important tool for analyzing the behavior of an arithmetic sequence. Knowing a common difference allows you to determine the nth term of the sequence, as well as the sum of the first n terms. It also helps you to identify patterns in the sequence and make predictions about future terms. Knowing a common difference is an essential part of analyzing arithmetic sequences.

The typical definition of the melting point is the temperature at which a substance transforms from a solid to a liquid.

What do you mean by melting point?

melting point, temperature at which the solid and liquid forms of a pure substance can exist in equilibrium. As heat is applied to a solid, its temperature will increase until the melting point is reached.

The melting point of a liquid is the temperature at which the liquid transforms from a solid to a liquid under atmospheric pressure. This is the location where the liquid and solid phases are equally present. The substance's melting point varies with pressure as well and is reported at standard pressure.

As the melting point is 0 °C.

So, it melts at 2 C. It can melt from 0 °C – 2 °C to 0 °C + 2 °C.

The measure of the angles of a triangle are 50°, 60°, 70°. The triangle is acute-angle triangle.

What is an acute angle?

An acute angle is one that is less than 90 degrees in length. This is a smaller angle than the right angle (which is equal to 90 degrees).

Given that the measure of the angles of a triangle are x, x+10, and x+20.

The sum of the interior angles of a triangle is 180°.

According to the question,

x+x+10+x+20 = 180°

3x + 30 = 180°

3x = 150°

Divide both sides by 3:

x = 50°.

Putting x = 50° in x, x+10, and x+20.

x =50° , x+10 = 60°, and x+20 =70°.

All angles of the triangle is 90°. Thus the triangle is an acute angle triangle.

if you used the same experimental design, but instead used an endotherm, you would expect to see a difference in the organism's ability to regulate its body temperature

If the same experimental design was used but with an endotherm (an organism that generates heat internally) instead of an ectotherm (an organism that relies on external sources of heat), I would expect to see a difference in the organism's ability to regulate its body temperature. Endotherms have a higher metabolic rate and are able to generate heat internally, whereas ectotherms rely on external sources of heat to regulate their body temperature. This means that endotherms would be less affected by changes in external temperature and would be able to maintain a more stable body temperature. Additionally, endotherms would likely have a higher tolerance for cold temperatures. I came to this conclusion because endotherms have internal heat regulation mechanisms that allow them to maintain a stable body temperature, whereas ectotherms do not.
