The equation 10x+5y=5 can be rewritten in slope-intercept form as y = -2x + 1. This equation's slope is -2 and the y-intercept is 1. The line intercepts the y-axis at (0,1) and for every 1 unit increase in x, y decreases by 2 units.

To write the equation 10x+5y=5 in slope-intercept form, you need to solve for y. The slope-intercept form is given by the equation y = mx + b, where m is the slope and b is the y-intercept.

First, divide the entire equation by 5 to simplify it:

(10x+5y)/5 = 5/5 becomes 2x + y = 1.

Then, solve the equation for y:

y = -2x + 1

The slope (m) of the equation is -2 and the y-intercept (b) is 1. Therefore, the line intercepts the y-axis at the point (0,1) and for every 1 unit increase in x, y decreases by 2 units due to the negative slope.

To graph this line, first plot the y-intercept at the point (0,1). Next, from this point, move right 1 unit (increase in x) and down 2 units (decrease in y) to get the point (1,-1). Draw a straight line through these points to represent the equation y = -2x + 1.

Answer:

The x intercepts are -4, -1 and 5 or (-4,0), (-1,0) and (5,0).

Step-by-step explanation:

Consider the provided graph.

Here we need to find the x intercepts of the function.

The x-intercepts are where the graph crosses the x-axis.

Here, the  provided graph crosses the x axis 3 times.

Thus there must be 3 x intercepts of the function.

Now label the points on which graph intersect the x axis as shown in figure 1.

Thus the labeled points are (-4,0), (-1,0) and (5,0)

Hence, the x intercepts are (-4,0), (-1,0) and (5,0) or -4, -1 and 5.

With a diameter of 12mm and using π as 3.14, the circumference is calculated as 37.68mm.

The circumference of a circle can be calculated using the formula:

Circumference = π x diameter

Given: Diameter = 12mm

Using π = 3.14:

Circumference = 3.14 x 12mm = 37.68mm

Therefore, the circumference of the circle is 37.68mm.

The expression 15/3x-6 evaluates to -4.75 when x=4. The solution involves substitution followed by the order of operations: first multiplication, then division, and finally subtraction.

The game which is 2.2 GB will need 170 minutes to download at a rate of 0.01 GB per minute. But the computer has only 120 minutes of battery life which is insufficient.

The total size of the game is 2.2 GB. The part that is already downloaded is 0.5 GB, so the remaining size of the game to be downloaded is 2.2 GB - 0.5 GB = 1.7 GB. Now, since the downloading speed is 0.01 GB/minute, we extrapolate the remaining time as (1.7 GB) / (0.01 GB/min) which equals 170 minutes.

(a) So, the inequality representing at least how many minutes it will take to download the rest of the game is x ≥ 170, where x is the required time in minutes.

(b) Two hours of battery life is equivalent to 2*60 = 120 minutes. Since 170 minutes is required to download the game and the available battery life is only 120 minutes, the battery will not be enough to download the game.

The estimated age of the parchment is approximately 4,086.17 years.

To estimate the age of the parchment, we can use the concept of carbon dating.

Carbon-14 (14C) is a radioactive isotope of carbon that is commonly used for dating archaeological artifacts.

The amount of 14C in an organism remains relatively constant while the organism is alive because it continuously takes in carbon from the atmosphere and food.

However, after the organism dies, it no longer takes in new carbon, and the 14C begins to decay at a known rate.

The half-life of carbon-14 is approximately 5,730 years. This means that after 5,730 years, half of the original amount of carbon-14 in a sample would have decayed.

Let's use the information provided: the parchment fragment had about 61% as much 14C radioactivity as does plant material on Earth today.

This means that the remaining 14C in the parchment is 61% of the original amount. The remaining 14C is the amount that has not yet decayed, and the rest has decayed over time.

Now, we can set up an equation:

[tex]0.61 = (1/2)^{(t/5730)[/tex]

Where:

t = time in years since the parchment was alive.

Now, we need to solve for 't.' Taking the logarithm of both sides to isolate 't':

[tex]\log(0.61) = (t/5730) \times \log(1/2)[/tex]

Now, solving for 't':

[tex]t = (5730 \times \log(0.61)) / \log(1/2)[/tex]

Using a calculator, we find:

t ≈ 4,086.17 years

So, the estimated age of the parchment is approximately 4,086.17 years.

Using the concept of radiocarbon dating and the fact that the parchment has 61% as much 14C radioactivity as present plant material, the calculated estimate for the parchment's age is approximately 2,200 years, rounded to the nearest hundred years.

To estimate the age of the parchment based on the information that it had about 61% as much 14C radioactivity as does plant material on Earth today, we use the concept of radiocarbon dating. The half-life of carbon-14 (14C) is 5,730 years, which means after every 5,730 years, the amount of 14C decreases by half. Given that the parchment retains 61% of its original 14C, we can formulate the decay equation to solve for the parchment's age.

The decay equation is given by: \(N_t = N_0(1/2)^{t/T}\), where \(N_t\) is the remaining amount of 14C, \(N_0\) is the original amount of 14C, \(t\) is time, and \(T\) is the half-life of 14C. In this case, \(N_t/N_0 = 0.61\), and we know \(T = 5730\) years.

By substituting the given values into the decay equation and solving for \(t\), we find that the parchment is approximately 2,200 years old, rounded to the nearest hundred years. This estimation assumes the natural 14C to 12C ratio in the atmosphere has been constant over the time period in question.

Answer:

Option C - Dependent because when the first flower is taken, it affects the ratio of the types of flowers in the vase.

Step-by-step explanation:

Given : A flower vase has 5 white lilies, 4 pink roses, and 6 yellow carnations.

One flower is chosen at random and given to a woman for her to keep.

Another flower is then chosen at random and given to a different woman for her to keep. Both women received a pink rose.

To find : Are these events independent or dependent?

Solution :

According to the statements,

The probability that the second woman receives a pink rose is dependent upon what the first woman receives.

Total flowers = 5+4+6=15

If the first woman does not receive a pink rose,

Then, the probability of the second woman receiving one is [tex]\frac{4}{15}[/tex]

If the first woman does receive a pink rose

Then, the probability of the second woman receiving one is  [tex]\frac{3}{15}=\frac{1}{5}[/tex]

Therefore, Option C is correct.

Dependent because when the first flower is taken, it affects the ratio of the types of flowers in the vase.
