The general equation for a circle is
[tex] {(x - h)}^{2} + {(y - k)}^{2} = {r}^{2} [/tex]
where (h, k) is the coordinates of the center of the circle and r is the radius. Since the circle passes through (4, 4) and (-4, -4), its center is located at the origin, which means its equation becomes
[tex] {x}^{2} + {y}^{2} = {( \sqrt{ {4}^{2} + {4}^{2} } )}^{2} = 32[/tex]
Solve the equation for x:
Answer:
A. x = 10
Step-by-step explanation:
-5x + 20 = -30
Subtract 20 from both sides
-5x = -50
Divide both sides by -5
x = 10
Answer:
A. x = 10
Step-by-step explanation:
- 5x + 20 = - 30
- 5x = - 30 - 20
- 5x = - 50
5x = 50
x = 50 / 5
x = 10

There are 11 shirts to select from in a store.
How many ways can 5 different shirts be selected?
PLEASE HELP
Given:
Total number of shirts to select from in a store = 11
To find:
How many ways can 5 different shirts be selected?
Solution:
Number of to select r items from n items is:
[tex]^nC_r=\dfrac{n!}{r!(n-r)!}[/tex]
Total number of ways to select 5 different shirts from 11 shirts is:
[tex]^{11}C_5=\dfrac{11!}{5!(11-5)!}[/tex]
[tex]^{11}C_5=\dfrac{11\times 10\times 9\times 8\times 7\times 6!}{5\times 4\times 3\times 2\times 1\times 6!}[/tex]
[tex]^{11}C_5=\dfrac{11\times 10\times 9\times 8\times 7}{5\times 4\times 3\times 2\times 1}[/tex]
[tex]^{11}C_5=462[/tex]
Therefore, there are 462 ways to select 5 different shirts.

On Tuesday, there were 400 customers at a movie theater, and each customer paid $8 for a ticket. On Wednesday, the owner of the movie theater reduced the regular ticket price from $8 to $6 for tickets that were purchased before 6 p.m. If the daily ticket sales for the two days were the same, and 100 people paid $8 for a ticket on Wednesday, how many people paid $6 for a ticket on Wednesday?
Answer:
400
Step-by-step explanation:
6x + 800 = 3200
6x = 3200 - 800
6x = 2400
= 2400 / 6
x = 400
Hope this answer helps you :)
Have a great day

The number of people who paid $6 for a ticket on Wednesday are 300.
What is subtraction?The act or process of subtracting is a mathematical operation in which the difference between two numbers or quantities is calculated.
According to the given question.
Number of tickets sales for Wednesday = 400
Also, on Wednesday number of people who paid $8 for tickets = 100
Therefor,
The number of people or customer who paid $6 for a ticket on Wednesday = Total number of people who purchased tickets - total number of people who purchased tickets for $8
[tex]= 400 - 100\\= 300[/tex]
Hence, the number of people who paid $6 for a ticket on Wednesday are 300.

Answer:
is it asking which one is a y coordinate?
Answer:
Q'(5, -3), R'(4, -1), S'(0, -2), T'(0, -5)
Step-by-step explanation:
Reflecting across the y-axis causes the x coordinate of a point to change to its opposite. So in terms of x and y: (x, y) ⇒ (-x, y)
Q(-5, -3) ⇒ Q'(5, -3)
R(-4, -1) ⇒ R'(4, -1)
S(0, -2) ⇒ S'(0, -2)
T(0, -5) ⇒ T'(0, -5)

Match each event to the likelihood of its occurrence. rolling a six-sided die and getting a 7 randomly selecting a girl from a team of 14 boys and 4 girls randomly selecting a short straw from a set of 12 short straws and 12 long straws picking a bird from a list of 20 bird species and 6 other animals likely arrowRight impossible arrowRight unlikely arrowRight neither likely nor unlikely arrowRight
A six sided die has numbers 1 through 6 so getting a 7 is impossible so the probability would be 0 (impossible)
14 + 4 = 18 total boys and girls
Picking a girl would be 1/18 this is low so ( unlikely)
12 short and 12 long straws = 24 total straws. Picking a short one would be 12/24 = 1/2 this is in the middle ( neither likely nor unlikely)
20 + 6 = 26 total animals
Picking a bird = 20/26 = 10/13, this is high ( likely)

There are 24 girls in a class. The ratio of girls to boys is 3:8.
How many boys are in the class?
Answer:
64 boys.
Step-by-step explanation:
There are 3 girls for every 8 boys.
24/3 = 8
8 * 8 = 64
The number of boys will be [tex]64[/tex] .
What is ratio ?Ratio is the comparison of two numbers i.e. how much a number contains other.
We have,
Number of girls [tex]=24[/tex]
Ratio of girls to boys [tex]=\ 3:8[/tex]
So,
According to the question,
Let number of girls [tex]=3x[/tex]
Number of boys [tex]=8x[/tex]
And,
We have number of girls so compare them,
i.e. [tex]3x=24[/tex]
⇒[tex]x= 8[/tex]
So, now putting value of [tex]x[/tex] in Number of boys,
i.e.
Number of boys [tex]=8x[/tex]
[tex]=8*8[/tex]
Number of boys [tex]=64[/tex]
Hence, we can say that the number of boys will be [tex]64[/tex] .

For all of the graphs:
Start the point on the number that I got from the inequality.
A filled circle means:
Greater than or equal to or less than or equal depending on where the line goes.
A hallow circle means:
Greater than or less than also depending on where the line is pointed towards too.
In order to graph an inequality you have to find and simply first then graph it.
For example on number 1, K ≤ -4.
Let's graph!
As you can see I filled in the circle and started at the point, -4.
Once I did it I made it bold from -4 and there on to the left. Making -4 be greater than or equal to K.
I showed that -4 is greater than or equal to K by making the line bold behind -4, also by filling in the circle.
