Answer:
This line passes through (0, -9)
Slope = 2
y = 2x-9
Step-by-step explanation:
Slope intercept form is : y=mx+b (m = slope, b= y-intercept)
First, let's distribute the 2 to the (x-6).
y-3 = 2x-12
Second, set it into slope intercept form (y = mx+b) by adding 3 to both sides.
y = 2x-9
This will be the equation in slope intercept form.
After looking at the the slope intercept form, we know that m = the slope. So the since the 2 is in the place of m when in slope intercept form, m=2. this would mean that the slope = 2.
Y-intercept is the point when the line touches the y-axis. To find the y-intercept, x would have to equal 0. This would mean that the point would have to be (0, y). After looking at the slope intercept form, and comparing it with our equation in slope intercept form, we know that -9 is in the place of b. This would mean that b = -9. This would also mean that the y-intercept is equal to -9. Therefore, the point would be (0, -9).

Subtracting polynomials
Answer:
Subtract the same degrees only.
Step-by-step explanation:
When subtracting polynomials, you can only subtract variables from those with the same degree (like term).
For example:
[tex]x^{2} -x^ = 0[/tex]
You can't subtract as the first x has a degree (exponent) of 2 and the second x has a degree of 1.
However, for example:
[tex]3x^{4} -1x^{4}=0[/tex]
You can subtract this to be [tex]2x^{4}[/tex] as both variables have a degree of 4.

The federal government spends slightly more on defense than Social Security.
We have,
The federal government spends different amounts of money on different programs and services every year, so there is no fixed answer to this question.
However, based on recent data, we can make some general statements about federal spending on defense and Social Security.
In the United States, defense spending typically makes up a significant portion of the federal budget, usually around 15-20%.
Social Security spending is also a major component of the federal budget, making up about 24% of total federal spending in recent years.
Thus,
Based on these figures, we can say that the federal government spends slightly more on Social Security than on defense.

100 points, please answer with full explanation.
Answer:
Part A
The amplitude of a cosine function is the distance between its highest and lowest points. In this case, the highest point is 8 feet and the lowest point is 8 - 12 = -4 feet, so the amplitude is 8 - (-4) = 12 feet.
The period of a cosine function is the time it takes for the function to complete one cycle of its movement. In this case, the bird completes one cycle of its movement every 16 seconds, so the period is 16 seconds.
Part B
The cosine function that could represent the situation is:
y = 6 cos(2πt / 16) + 8
This function has an amplitude of 6 feet and a period of 16 seconds. It also passes through the point (0, 8) when t = 0, which is the condition given in the problem.
Part C
The bird will reach its lowest height when the cosine function is equal to -6. This happens when 2πt / 16 = π / 2, or t = 4 seconds.
Here is a graph of the function:

In 1939, an earthquake measuring 8.3 occurred in Chillan, Chile, killing 28 000 people. In 1999, an earthquake in Taiwan measured 7.6 on the Richter scale and killed 2100 people. Compare the intensities of the two earthquakes. (THE ASNWER IS 5).
The Chillan earthquake had an intensity about 5 times greater than the Taiwan earthquake.
The Richter scale is logarithmic, meaning that a difference of 1 on the scale corresponds to a tenfold difference in the amplitude of the seismic waves. Therefore, we can calculate the difference in intensity between the two earthquakes using the formula:
difference in intensity
= 1[tex]0^{((magnitude of earthquake 1) - (magnitude of earthquake 2))[/tex]
For the Chillan earthquake:
magnitude = 8.3
difference in magnitude = 8.3 - 7.6 = 0.7
For the Taiwan earthquake:
magnitude = 7.6
Plugging these values into the formula, we get:
difference in intensity = 10^(0.7) = 5.01187
This means that the Chillan earthquake had an intensity about 5 times greater than the Taiwan earthquake.

In ΔPQR, sin P = 0.5, sin R = 0.3 and r = 13. Find the length of p.
The length of side p is approximately 21.67
In triangle PQR, we are given the values of sin P, sin R, and the length of side r. We need to find the length of side p.
We can use the law of sines to solve this problem. The law of sines states that the ratio of the length of a side of a triangle to the sine of the opposite angle is constant. Mathematically, it can be represented as:
p / sin P = r / sin R
Plugging in the given values, we have:
p / 0.5 = 13 / 0.3
Cross-multiplying, we get:
0.3p = 13 * 0.5
0.3p = 6.5
Dividing both sides by 0.3, we find:
p ≈ 21.67

Given that the area of a rectangle is equal to its length multiplied by its width, we can set up the equation as follows:
Area = Length × Width
In this case, the area is given as (x^2 - 12x + 35), and the length is (x - 5). We are asked to find the width.
So, we can rewrite the equation as:

Solve the inequality involving absolute value. |x−2| 5≥11
The solution to the inequality |x − 2| ≥ 5 is x ≤ -3 or x ≥ 7.
We have,
To solve the inequality |x − 2| ≥ 5, we need to consider two cases:
Case 1:
x - 2 is non-negative (i.e., x - 2 ≥ 0)
In this case, the absolute value simplifies to x - 2, so we have:
x - 2 ≥ 5
Adding 2 to both sides, we get:
x ≥ 7
So any value of x that is greater than or equal to 7 satisfies the inequality.
Case 2:
x - 2 is negative (i.e., x - 2 < 0)
In this case, the absolute value simplifies to -(x - 2), so we have:
-(x - 2) ≥ 5
Multiplying both sides by -1, we get:
x - 2 ≤ -5
Adding 2 to both sides, we get:
x ≤ -3
So any value of x that is less than or equal to -3 satisfies the inequality.
Therefore,
The solution to the inequality |x − 2| ≥ 5 is x ≤ -3 or x ≥ 7.

Sketch the graphs of the absolute value functions y = - |x + 6|
The Absolute value function takes the same value for positive and negative values of its argument.
The graph of the absolute value function y = -|x + 6|, we first need to understand the properties of an absolute value function.
The absolute value of a number is its distance from 0 on the number line. Thus, the absolute value function |x| will always return a non-negative value, regardless of the sign of x. When the absolute value function is multiplied by -1, as in -|x|, the function reflects the graph over the x-axis and makes it negative.
Applying these principles to the given function y = -|x + 6|, we can start by identifying the vertex, which is the point where the absolute value term inside the function equals 0. In this case, the vertex is at x = -6.
Next, we can plot some points to get a sense of the shape of the graph. We can choose values of x that are greater than or less than -6, and use the fact that the function is negative to find the corresponding y-values. For example:
- When x = -7, y = -|(-7) + 6| = -1
- When x = -5, y = -|(-5) + 6| = -1
We can see that the graph has a "V" shape, with the vertex at (-6,0). The line of symmetry is the vertical line passing through the vertex, which is the equation x = -6. The graph approaches the x-axis on either side of the vertex, but never touches it. The negative sign in front of the absolute value term causes the graph to be reflected over the x-axis.
since the absolute value function takes the same value for positive and negative values of its argument.
