Describe the process for
graphing the equation
y =-1/2x- 1
Answers
the formula is y=mx+b
m is the slope
b is the y-intercept form
so the -1 is the y-intercept form. so you need to start at that point on the y axis. then the slope which is -1/2 comes into play. in my school we use rise/run. so from the point you marked at -1 you will go down 1 and to the right 2 points then where you stop is your next point (mark it) keep doing that. also go up the other way from the -1 point. go up 1 and to the left 2. then connect all of your points with a line. I hope this helped.

*Most of these, you just have to get the variable by itself. To check, put the answer in for the letter.*
1. b+8=14
Subtract 8 from both sides
b=6
Check: 6+8=14 ——— 14=14
2. 25-t=15
Subtract 25 from both sides
-t = -10 ––Divide both sides by -1
t=10
Check: 25-10=15 ——— 15=15
3. 9p=81
Divide both sides by 9 to get p alone
p=9
Check: 9(9)=81 ——— 81=81
4. y/7= 2
Multiply both sides by 7 to cancel out the fraction
y=14
Check: 14/7=2 ——— 2=2
5. y+6=10
Subtract 6 from both sides
y=4
Check: 4+6=10 ——— 10=10
6. f-4=9
Add 4 to both sides
f=13
Check: 13-4=9 ——— 9=9
7. 8d=48
Divide both sides by 8 to get d alone
d=6
Check: 8(6)=48 ——— 48=48
8. 10 = r/5
Multiply both sides by 5 to cancel out the fraction
50 = r
Check: 10=50/5 ——— 10=10

for the x-values 1,2,3 and so on, the y values of a function form an arithmetic sequence that decreases in value what type of function is it
A. Decreasing linear
B. Exponential growth
C. Increasing linear
D. Exponential decay
Answers
The type of function that fits the given description is D. Exponential decay.
In an arithmetic sequence, the difference between consecutive terms remains constant. If the y-values of a function form an arithmetic sequence that decreases in value, it means that the difference between consecutive terms is negative.
Exponential decay functions exhibit a constant ratio between consecutive terms, resulting in a decreasing sequence. As the x-values increase, the y-values decrease at a consistent rate. This is represented by the formula y = ab^x, where b is a constant between 0 and 1.
In contrast, linear functions have a constant difference between consecutive terms, resulting in an arithmetic sequence. However, since the y-values are decreasing, the function cannot be linear.
Exponential growth functions, on the other hand, have a constant ratio between consecutive terms, but they result in an increasing sequence. The y-values of an exponential growth function increase as the x-values increase.
Therefore, based on the given information, the most appropriate type of function is D. Exponential decay.

Answer: (0,-1)
Step-by-step explanation:
Let's start with the first inequality, \(y < -x^{2}+x\). To check which points satisfy this inequality, we can substitute the x- and y-coordinates and see if they satisfy the inequality.
A) \(-1 < -0^{2}+0 \longrightarrow -1 < 0 \longrightarrow \text{ True}\)B) \(1 < -1^{2}+1 \longrightarrow 1 < 0 \longrightarrow \text{ False}\)C) \(-3 < -2^{2}+2 \longrightarrow -3 < -2 \longrightarrow \text{ True}\)D) \(-6 < -3^{2}+3 \longrightarrow -6 < -6 \longrightarrow \text{ False}\)Once again, we can repeat this for the second inequality (but this time, we only need to check the points that satisfy the first inequality).
A) \(-1 > 0^{2}-4 \longrightarrow -1 > -4 \longrightarrow \text{ True}\)C) \(-3 > 2^{2}-4 \longrightarrow -3 > 0 \longrightarrow \text{ False}\)Therefore, the answer is (A) (0, -1).

8. If 1.2% of the population has a certain disease, compute the probability that exactly three of two hundred randomly chosen individuals will have the disease.
Answers
The probability that exactly three out of two hundred randomly chosen individuals will have the disease is approximately 0.1668 or 16.68%.
To solve this problem, we need to use the binomial distribution formula. The binomial distribution is a probability distribution that describes the number of successes in a fixed number of independent trials, where each trial has only two possible outcomes (success or failure) and the probability of success is constant.
In this case, the probability of success is 1.2%, which is equivalent to 0.012. The number of trials is 200, and we want to know the probability of exactly three successes.
The formula for the probability of exactly k successes in n trials is:
P(k) = (n choose k) * p^k * (1-p)^(n-k)
where "n choose k" represents the number of ways to choose k items from a set of n items, and p is the probability of success.
Using this formula and plugging in the values we have, we get:
P(3) = (200 choose 3) * 0.012^3 * (1-0.012)^(200-3)
P(3) = (200! / (3! * 197!)) * 0.012^3 * 0.988^197
P(3) = 0.1668
Therefore, the probability that exactly three out of two hundred randomly chosen individuals will have the disease is approximately 0.1668 or 16.68%. This means that if we were to repeat this experiment many times, we would expect to see about 16.68% of the time that exactly three people out of two hundred have the disease.

Answers
The area of this polygon is equal to 428 ft².
How to calculate the area of this polygon?In order to calculate the area of this polygon, we would have to determine the total area of the two different parts of the given composite figure.
Therefore, the total area of this polygon is the sum of the area of the each geometric figure (rectangle):
Area of rectangle A = Length × Width
Area of rectangle A = 13 × 26
Area of rectangle A = 338 ft²
Area of rectangle B = 9 × (23 - 13)
Area of rectangle B = 9 × 10
Area of rectangle B = 90 ft²
Therefore, total area is given by:
Total area = 90 + 338

The perimeter is the sum of the lengths of the sides of a closed plane figure.
The total distance from the outside of the closed figure is called the perimeter. Sum of all sides of a closed figure. The formula is: perimeter = sum of all sides
The units for the perimeter of a polygon remain the same as the units for each side. If the sides have different units, convert them to the same units and then find the perimeter.
Perimeter of a regular polygonA regular polygon has all equal sides. So if the polygon has 'n' sides, add the same length 'n' times. Perimeter of regular polygon = (length of one side) × number of sides

A gym's membership in 2012 was 9,300. The current membership is 2,800. Which expression can be used to find the percent of change? WHAT EXPRESSION NOT WHAT THE PERCENT IT.
Answers
The expression that can be used to find the percent of change between the gym's membership in 2012 and the current membership is ((Current Value - Initial Value) / Initial Value) \(\times\) 100.
To find the percent of change between the gym's membership in 2012 and the current membership, we can use the following expression:
Percent of change = ((Current Value - Initial Value) / Initial Value) \(\times\) 100
In this case, the initial value is 9,300 (membership in 2012), and the current value is 2,800 (current membership).
Substituting these values into the expression, we get:
Percent of change = ((2,800 - 9,300) / 9,300) \(\times\)100
Simplifying the expression further, we have:
Percent of change = (-6,500 / 9,300) \(\times\) 100
Therefore, the expression that can be used to find the percent of change between the gym's membership in 2012 and the current membership is ((Current Value - Initial Value) / Initial Value) \(\times\)100. This formula calculates the relative difference between the initial and current values and expresses it as a percentage.
