Suppose n-15 is a whole number. What do you know about the value of n? Explain
Answer:
N is an integer
Step-by-step explanation:
Answer:
n = 15
Step-by-step explanation:
Solve for n:
n - 15 = 0
Hint: | Isolate terms with n to the left hand side.
Add 15 to both sides:
n + (15 - 15) = 15
Hint: | Look for the difference of two identical terms.
15 - 15 = 0:
Answer: n = 15

is x=15 a function?
Answer:So x=15 does not define a function. Another way of describing the condition above is that x=15 fails the vertical line test - the requirement that any vertical line intersects the graph in at most one point. This fails when x=15 because a vertical line at that point intersects the graph at infinitely many points.
Step-by-step explanation:
No x=15 is not a function.
What is Mathematical function ?
Function is defined as the expression or relation between any given two variables such as x and y and there must be an independent variable and dependent variable.
In other words the function represents the graph between x and y that is for each value of x there exist one value of y but here there is no restriction in values of y that is y can have infinity values.
Therefore, x=15 is not a function.

Answer:
(x, y, z ) = (4, 8, 12 )
Step-by-step explanation:
Given
x + y + z = 24 → (1)
5x + 3y + z = 56 → (2)
x + y - z = 0 → (3)
Eliminating z from the equations
Add (1) and (3) term by term
2x + 2y = 24 → (4)
Subtract (1) from (2) term by term
4x + 2y = 32 → (5)
Subtract (4) from (5) term by term
2x = 8 ( divide both sides by 2 )
x = 4
Substitute x = 4 into (4)
2(4) + 2y = 24
8 + 2y = 24 ( subtract 8 from both sides )
2y = 16 ( divide both sides by 2 )
y = 8
Substitute x = 4, y = 8 into (1)
4 + 8 + z = 24, that is
12 + z = 24 ( subtract 12 from both sides )
z = 12
Solution is x = 4, y = 8, z = 12

The populations of two towns, town A and town B, are being compared. The population of town A is 4×10↑4 and the population of B is 2×10↑5. How many times greater is the population of town B than town A?
Answer:
The population of town B is 5 times greater than the population of town A
Step-by-step explanation:
Here in this question, we want to know the number of times in which the population of town B is greater than that of town A
To get the number of times, we simply divide the population of town B by the population of town A
From the question, the population of town B is 2 * 10^5 while the population of town A is 4 * 10^4
So to know the number of times,
We have (2 * 10^5) /(4 * 10^4) = 5
The population of town B is 5 times greater than the population of town A

The middle level has 80 more than 3 times as many seats as the upper level. How many seats are in the middle level?
A 450 seats
B 800 seats
C 1,250 seats
D 1,430 seats
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
If the lower level has 100 less than 2 times as many seats as the upper level then the expression is 2x-100 and the middle level has 80 more than 3 times as many seats as the upper level so it's 3x+80 and lastly the top level is just x.
so now for the equation you would add all those expressions and they all should equal 2680:
[tex]x+3x+80+2x-100=2680\\6x-20=2680\\6x=2700\\x=450[/tex]
but now don't forget to plug in for the middle level:
[tex]3x+80\\3(450)+80\\1350+80\\1430[/tex]
Therefore the middle level has 1430 seats.

Answer:
g(-2) = -7
Step-by-step explanation:
To find g(-2), plug -2 into g(x).
g(x) = -4x² + 3x + 15
g(-2) = -4(-2)² + 3(-2) + 15
g(-2) = -4(4) + 3(-2) + 15
g(-2) = -16 + (-6) + 15
g(-2) = -1 + (-6)
g(-2) = -7
A hiker climbs a mountain. After 1 hour he is at an altitude of 200 feet. After 3 hours, he is at an altitude of 350 feet. What is the rate of change?
Answer: 75 feet per hour
Step-by-step explanation:
X: 1, 3
Y: 200, 350
150/2
75
The rate of change in altitude is 75 feet per hour.
What is rate?Rate is a measurement to determine the change in one quantity with respect to another quantity.
Given that,
Altitude of hiker after 1 hour = 200 feet
Altitude of hiker after 3 hours = 350 feet
The change in altitude = 350-200 = 150 feet
The difference of time = 3 - 1 = 2 hours
Rate of change = change in altitude/ change is time
= 150/2
= 75 feet per hour
The rate of change in altitude of the hiker is 75 feet per hour.
