Seth's father is thinking of buying his son a six-month movie pass for $25. With the pass, movies cost $2
each.
Write a linear equation to represent the total cost spent of Seth seeing movies for the next 6 months.
x = number of movies
y = total cost
========================================================
Explanation:
The starting cost is $25, which is the amount spent even if no movies are watched.
Since x is the number of movies, and each costs $2, this means Seth spends an extra 2x dollars more on top of the $25 already spent.
In total, the cost is 2x+25 which leads to y = 2x+25
This linear equation is in slope intercept form y = mx+b
m = 2 = slope
b = 25 = y intercept

What is the area of quadrilateral DYES?
Answer:
16.97
Step-by-step explanation:
you need to find the length of DY (the hypotenuse of one of the triangles), and to do that, you need to find the length of CY, so subtract AB (which is 1) from AY (which is 5) and you are left with 4. then use the Pythagorean theorem to solve for DY. [tex]1^{2}[/tex] + [tex]4^{2}[/tex] = [tex]17^{2}[/tex]. [tex]\sqrt{17}[/tex] = 4.12 (rounded to the nearest hundredth). The last step is to solve for area, or length times height. The quadrilateral has equal side lengths, so the equation is
4.12 × 4.12 which equals 16.97

(GIVING BRAINLIEST) Gavin has two bags of tiles. The numbers and colors of the tiles are shown in the table.
If Gavin randomly draws one tile from each bag, what is the probability that he will select two red tiles?
a. 2/9
b. 1/6
c. 1/18
d. 1/3
The probability that Gavin will select two red tiles when he randomly draws one tile from each bag is 1/18. So, option C is the correct answer.
What is the probability of an event?The probability of an event is a fractional value determining how likely an event is to occur. The formula of the probability of an event =
The number of favorable outcomes to an event/total number of outcomes in that event.
What are independent events?Two events A and B are said to be independent when the occurrence is not related to the occurrence of the other.
The probability of independent events is given by:
Probability(both A and B occurs) = Probability(A occurs)*Probability(B occurs)
How do we solve the given question?We are informed that Gavin has two bags of tiles, and he draws one tile from each bag.
We are asked to find the probability that he will select two red tiles.
Let the event of drawing a red tile from bag 1 be A and bag 2 be B.
Since the two bags are different, A and B are independent events.
Now, the number of red tiles in bag 1 = 3. These are in favor of A.
The total number of tiles in bag 1 = 18.
∴ Probability(A) = 3/18
or, P(A) = 1/6.
Now, the number of red tiles in bag 2 = 3. These are in favor of B.
The total number of tiles in bag 2 = 9.
∴ Probability(B) = 3/9
or, P(B) = 1/3.
Since A and B are independent, the occurrence of A and B together is,
Probability (A and B) = P(A)*P(B)
or, P(A and B) = 1/6 * 1/3 = 1/18.
∴ The probability that Gavin will select two red tiles is 1/18.
Hence, option C. is the correct option.

Select the correct answer from the drop-down menu. A whole number is 6 more than 2 times another number. The sum of the two numbers is less than 50. This can be written in an inequality as x + 2x + 6 < 50, where x represents the smaller number. From the set {13, 14, 15, 16, 17}, the values of x for which the inequality holds true are ____.
Answer:
Step-by-step explanation:
First, you have to simplify and solve for x.
x + 2x + 6 < 50
3x + 6 < 50
3x < 44
x < 14 2/3
x has to be smaller than 14 2/3. The only two numbers in the set that works are {13, 14} replace x with both numbers and solve
14 + (28) + 6 = 50
13 + (26) + 6 < 50
the correct answer is 13

Triangle XYZ has vertices X(−2, −1), Y(0, 2), and Z(2, −1)
Answer:
Image after the rotation would be X(2, 1) Y(0,-2) and Z(-2, 1)
Step-by-step explanation: 180 clockwise or counterclockwise formula is that (x,y) becomes (-x,-y). This means that the coordinates are inverted to positive or negative.
The image after the rotation would be X(2, 1) Y(0,-2) and Z(-2, 1) according to the graph below.
What is a Graph?This is defined as a pictorial representation of numbers or variables in an organized manner.
180 clockwise or counterclockwise means that (x,y) becomes (-x,-y). This means that the coordinates are inverted to positive or negative depending on their respective signs.
This therefore means X(−2, −1), Y(0, 2), and Z(2, −1) = X(2, 1) Y(0,-2) and Z(-2, 1) .

A row of lockers has a length of 72 inches and a width of 60 inches. Gabrielle made a scale drawing of the row of lockers using a scale of 1/2 centimeters = 6 inches.
Answer:
Length- 6 centimeters. Width- 5 centimeters
Step-by-step explanation:
Ok, so 1/2 centimeter = 6 inches
let’s first take the length witch is 72 inches and divide that by 6. Then, since it half a centimeter, divide in half.
72/6 = 12 12/2 = 6 centimeters
Next is the width. Now we the same thing as the length. Take 60 and divide by 6 then divide in half.
69/6 = 10. 10/2 = 5 centimeters
In summary, The scale drawing has length of 6 centimeters and a width of 5 centimeters.

Japan 80.09 = 16.018
Switzerland 75.81 = 15.162
Answer:
In Japan, the average ticket costs $17.73.
In Switzerland, the average ticket costs $13.45
Step-by-step explanation:
80.09-75.81=3j+2s-(2j+3s)
4.28=j-s
So a ticket from Japan costs $4.28 more than a ticket from Switzerland. so we can write the equation:
3s+2(s+4.28)=75.81
5s=67.25
s=13.45, j=13.45+4.28=17.73

Answer:
The equation relating the number of cars to the number of passengers is p = 4n
Step-by-step explanation:
Given that certain type of car has room for 4 passengers
To find: write an equation relating the number of cars to the number of passengers
Let "n" be the number of cars
Let "p" be the number of passengers
From given information,
Car has room for 4 passengers. Therefore, we can frame,
number of passengers = 4 ( number of cars )
p = 4 (n)
p = 4n
Thus the equation relating the number of cars to the number of passengers is p = 4n
