m=y_2-y_1/x_2-x_1m=100-50/2-1m=50Which of these graphs represents a function
Answer: Answer X
Step-by-step explanation:
In order for a graph to represent a function, it must pass the vertical line test. This means, if you were to draw a vertical line at ANY point along the graph, it should not intersect more than one point. For answers W, Y, and Z, they clearly fail the vertical line test. Answer X is the only graph that passes the vertical line test.

We see that 2 is the GCF of 22 and 18. It's the largest shared factor.
Now use the distributive property to say the following
22 + 18
2*11 + 2*9
2(11+9)
To check the answer, multiply the outer 2 by each term inside to end up with 22+18 again.

Indira drew 3 animals: an eagle, a snake, and a shark. She drew each animal twice, once with green eyes and once with red eyes. Ten students chose their favorite drawing. Three of them chose the shark with red eyes.
How many possible outcomes are there in the sample space of her experiment? Based on the results, what is the experimental probability that a shark with red eyes is not picked, written as a percent?
(PLEASE HELP!!)
Since each of the 10 students has 3 choices, there are [tex]3^{10}[/tex] possible outcomes in the sample space of her experiment.
Using the probability concept, it is found that there is a 70% experimental probability that a shark with red eyes is not picked.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
For an experimental probability, these numbers of outcomes are taken from previous trials.
In this problem, out of 10 students, 3 choose the shark with red eyes, hence 7 did not choose them, thus:
p = 7/10 = 0.7 = 70%.
Hence, there is a 70% experimental probability that a shark with red eyes is not picked.
For the total number of outcomes, there are 10 students, each with 3 choices, hence there are there are [tex]3 \times 3 \times 3 \cdots \times 3 = 3^{10}[/tex] possible outcomes in the sample space of her experiment.

Q.1. The potter at a pottery store makes two sizes of vases. The larger size takes six hours to make, and the smaller size takes 1.5 hours to make. The potter works 30 hours a week. She needs to make at least six total vases a week, including at least two of each size. Give one example of how many of each type of vase the potter can make.
Answer:
Step-by-step explanation:
Let x and y be the large (x) and small (y) vases the potter makes in one week.
We are told that the large and small vases require 6 hours for each large(x) and 1.5 hours for each small (y) vase. The combination of large and small vases made in one week thus requires a total time of:
6x + 1.5y = total hours/week
We are told that the potter works 30 hours per week, so:
6x + 1.5y = 30 hours
We also learn that she needs to make at least 6 vases in a week, so:
x + y => 6
Plot the two equations:
6x + 1.5y = 30, and
x + y => 6
This will produce the attached grap, Vases1. The inequality appears as the shaded area in the upper area. Any point in the shaded area satisfies the inequality of x + y => 6. The x and y intercepts are at (0,6) and (6,0), representing either all large (x) or small vases (y).
The lines intersect at (4.67,1.33). This represents a fictional combination of 4.67 large and 1.33 small vases. This results in 6 vases (4.67 + 1.33) that require a total of 30 hours to make (6*4.67 + 1.5*1.33) = 30 hours. If you want to select whole number answers, they appear at (0,6), (2,4), (4,2), and (6,0). (x,y or large,small). All combinations result in 6 vases, but eould require less than the 30 hours of time available. Any whole number combination in the area below the line 6x + 1.5y = 30, but above the line x+y =>6 are valid, such as (4,4). This area is shown in Vases2. The valid area for making choices has the darkest shade, where the two inequalities are both satisfied.

For his phone service, Ryan pays a monthly fee of $10, and he pays an additional $0.06 per minute of use. The least he has been charged in a month is $92.74. What are the possible numbers of minutes he has used his phone in a month? Use m for the number of minutes, and solve your inequality for m.
Answer:
$92.74 = 0.06m + $10
m = 1545.67 (or 1546 if rounded to the nearest whole minute)
Step-by-step explanation:
m represents the number of minutes, which we have been told are charged at $0.06 per minute.
$10 is the constant because he is charged this every month.
Set up the equation with these numbers:
92.74 = 0.06m + 10
Now solve the equation
Subtract 10 from both sides to get m by itself:
92.74 - 10 = 0.06m + 10 - 10
82.74 = 0.06m
Divide each side by 0.06 to get m as a whole number
92.74/0.06 = 1545.67
0.06m/0.06 = m
Therefore
m = 1545.67 (or 1546 if rounded to the nearest whole minute)

rock hit the ground? e) Graph the relation.
a) h = 12 ft, b) h = - 0.5 · (d - 6) · (d + 4), c) d₁ = 6, d₂ = -4, d) 6 ft, e) Please see the image attached below for further details.
How to analyze a second order polynomial related to the trajectory of the rock under parabolical motion
An object is under a parabolical motion, when it has a horizontal motion at constant velocity and a vertical motion uniformly accelerated by gravity and effects from air viscosity are neglected. In this case, the trajectory is described by second order polynomial (quadratic function).
a) The height of the cliff is found by evaluating the function at d = 0:
h = - 0.5 · 0² + 0 + 12
h = 12 ft
The initial height of the cliff is 12 feet. [tex]\blacksquare[/tex]
b) The intercept form of the quadratic function is found by algebraic procedures:
h = - 0.5 · d² + d + 12
h = - 0.5 · (d² - 2 · d - 24)
h = - 0.5 · (d - 6) · (d + 4)
The relation in intercept form is h = - 0.5 · (d - 6) · (d + 4). [tex]\blacksquare[/tex]
c) The zeros of the relation are d₁ = 6 and d₂ = -4. [tex]\blacksquare[/tex]

Find the missing side lengths. ( BC and DE)
Answer:
BC= 24, DE= 15
Step-by-step explanation:
You can use the Pythagroean theorem which is a^2+b^2=c^2.
So AC is the hypotenuse, so a^2+10^2=26^2=a^2+100=676. Subtract 100, a^2=576. Then take the square root of 576 which is 24.
EC is the hypothenuse for triangle EDC, so a^2+36^2=39^2, a^2+1296=1521. Then subtract to 1296 to get 225. Then take the square root which is 15.
