Answer:
Answer:
[tex]y=15[/tex]
Step-by-step explanation:
Insert the given value of x into the equation:
[tex]x=5\\\\y=|x|+10\\\\y=|5|+10[/tex]
The absolute value of a number is its distance from zero on the number line. Therefore, the absolute value of a number will always be positive. The distance of 5 from zero on the number line is:
[tex]y=5+10\\\\y=15[/tex]

x - у - 2z = -6
3х + 2y = -25
—4х + у — z = 12
Answer:
(1) x-y-2z=-6 , (2) 3x+2y=-25 , (3) -4x+y-z=12
Step-by-step explanation:
Multiply (3) by 2,
-8x + 2y - 2z = 24
subtract above equation from (1)
9x - 3y = -30 --> 3x - y = - 10
subtract above equation from (2)
3y = -15 --> y = -5
Put y value back into (2)
3x + 2(-5) = -25 --> 3x - 10 = -25 --> 3x = -15 --> x = -5
Put x and y values into (3)
-4(-5) + (-5) - z = 12 --> 20 - 5 - z = 12 --> 15 - z = 12 --> z = 3
Hope its right good luck!!

(04.01 LC) Which set of ordered pairs represents a function? (1 point) {(0, 1), (1, 2), (2, 3), (3, 3)} {(0, 1), (1, 2), (1, 3), (2, 5)} {(0, 0), (1, 2), (2, 4), (2, 6)} {(0, 0), (0, 1), (2, 0), (2, 4)}
The first set:
" {(0, 1), (1, 2), (2, 3), (3, 3)}"
Represents a function.
Which set of ordered pairs represents a function?
A function is a relationship that maps elements from a set (inputs) into elements from another set (output). Such that each input can be mapped into only one output.
Then, for example, the second set:
{(0, 1), (1, 2), (1, 3), (2, 5)}
Is not a function, because the input x = 1 is being mapped into y = 2 and y = 3.
The only case where the inputs are not repeated is on the first set:
" {(0, 1), (1, 2), (2, 3), (3, 3)}"
Where no input is repeated, so this is a function.

A symphony orchestra is arranged in a semicircle around the conductor. The rows are about 3 feet apart, with the first row about 6 feet from the conductor. A mid-sized orchestra has about 6 rows of chairs. What is the approximate delay between the instant when a play at the 6th row start a note and when the conductor hears the note?
Answer:
19 ms
Step-by-step explanation:
We need to find the time it takes for the sound from the 6th row gets to the conductor.
Since there are 6 rows and each row is 3 feet apart, since the orchestra is arranged in a semi-circular manner around the conductor, the distance from the 6 th row to the 1st row is (6 - 1) × 3 = 5 × 3 = 15 feet.
Now, since the conductor is 6 feet from the first row, his distance from the 6th row is 15 feet + 6 feet = 21 feet.
So, time approximate delay between the instant when a play at the 6th row start a note and when the conductor hears the note, t = distance between 6th row and conductor/speed of sound.
Speed of sound = 343 m/s
distance between 6th row and conductor = 21 feet. In meters, it is 21 × 0.3048 m = 6.4008 m
t = 6.4008 m ÷ 343 m/s
= 0.019 s
= 19 ms

At the beginning of the season, Jamie pays full price for a ticket to see the panthers, her favorite basketball team. The panthers currently have 33 wins and 31 losses. Represent the total change in the cost of a ticket given their losses. What is the cost of a ticket for the next game they play
Answer:
The answer is below
Step-by-step explanation:
Given that the price of the ticket at the beginning of the season is $49.64 and the ticket price decrease by $0.41 for every loss
a) The cost of the ticket decreases by $0.41 for every game loss, therefore after 31 losses, the change in cost of ticket is given as:
Change in cost = -$0.41 × number of losses = -$0.41 × 31 = -$12.71
b) The cost of a ticket for the next game given they have 31 losses is:
Cost of ticket = Initial cost of ticket + change in cost = $49.64 - $12.71 = $36.93

In the first year the population increased by only one deer, but between years seven and eight the population grew by two deer, showing that the growth rate continuously doubles. B.The blue line shows a deer population that grew with a linear growth rate, because the graph shows that the population increased by approximately one deer per year. C. The red line shows a linear growth rate, because an approximate straight line estimates a growth rate of five deer per year. D. The red line demonstrates an exponential growth rate, because the growth rate for the deer population is itself continuously increasing

The median number of magazine appearances made by 7 models is 5. The range of number of magazine appearances by those models is 5. Determine if the following statement is true, is false, or does not contain enough information. If the fewest magazine appearances is 3, then the greatest number of appearances is 9.
Answer:not enough information
Step-by-step explanation:
Using definition of range = greatest - lowest , we found that given statement is false.
What is range of a given data?Range of a data is the difference between the highest and lowest quantity in the given data.
For example : Given data is 2,5,9,5,1
Range of this data = Highest - Lowest = 9-1 =8
Given the data of the number of appearances made by 7models
Median = 5
Range = 5
If the fewest magazine appearances is 3
We know that Range = Greatest number of appearances - fewest appearances
⇒ 5 = Greatest number of appearances - 3
⇒ 5 +3 = Greatest number of appearances
∴Greatest number of appearances = 5+3 = 8
But given is that the Greatest number of appearances will be 9 in the given statement.
∴ The given statement is false.
