(-∞,-16)U(16/9,5)
Answer:
n = 3,4,5
Step-by-step explanation:
3n + 4 < 19
3n ≤ 15
n ≤ 5
10n/n+16 > 1
10n > n²+16
-n²+10n-16
(-n+2)(n-8)
n = 2 or n = 8
2 < n < 8
So 2<n≤5 = 3,4,5
The library is having a book sale. Hardcover books sell for $4 each, and paperback books are $2 each. If Ayanna spends $26 for 8 books, how many hardcover books did she buy?
Answer:
5 hardcover books
Step-by-step explanation:
x + y = 8 ↔ Assume x for hardcover books and y for paperback cover
4x + 2y = 26 ↔ Total cost of 8 books is $26
-2x - 2y = -16 ↔ Multiply Equation 1 by -2 so that the coefficients of y is opposite
2x = 10 ↔ Add the two equations to eliminate y
x = 5 ↔ Divide each side by 2

List the steps to solve the fol
lowing equation:
5x - 6 = 44. Then solve for x
Answer:
x = 10
Step-by-step explanation:
Simplifying
5x + -6 = 44
Reorder the terms:
-6 + 5x = 44
Solving
-6 + 5x = 44
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '6' to each side of the equation.
-6 + 6 + 5x = 44 + 6
Combine like terms: -6 + 6 = 0
0 + 5x = 44 + 6
5x = 44 + 6
Combine like terms: 44 + 6 = 50
5x = 50
Divide each side by '5'.
x = 10
Simplifying
x = 10

Suppose a city with a population of 200,000 has been growing at a rate of 3% per year. If this rate continues, find the population of this city in 21 years. Round to the nearest whole number as needed (1 point)
Answer:
Growing at a rate of 3% per year : 200,000 x 3% = 6,000 population/ year
The population of this city in 21 years : 200,000 + ( 6,000 x 21 ) = 326,000 p
Step-by-step explanation:
The population of the city after 21 years is given by the exponential equation A = 372,059
What is exponential growth factor?The exponential growth rate is the value which increases exponentially over a period of time and
x ( t ) = x₀ ( 1 + r )ⁿ
x ( t ) is the growth at time t
x₀ is the initial value growth at time t = 0.
r is the growth rate expressed as percentage when r > 0
And , the decay rate when r < 0 , in percentage
t is the time in discrete intervals and selected time units
Given data ,
Let the exponential equation be represented as A
Now , the value of A is
Let the initial population of the city be x₀ = 200,000
Now , let the number of years be n = 21 years
Let the percentage of increase be r = 3 %
And , exponential growth formula is given by
x ( t ) = x₀ × ( 1 + r )ⁿ
x ( 21 ) = 200,000 ( 1 + 0.03 )²¹
On simplifying the equation , we get
x ( 21 ) = 200,00 ( 1.03 )²¹
x ( 21 ) = 200,000 ( 1.86029457 )
On further simplification , we get
x ( 21 ) = 3,72,058.914
On rounding the population , we get
x ( 21 ) = 372,059
Therefore , the value of A is 372,059
Hence , the exponential growth of the population after 21 years is 372,059

Find the sum of 3x + y , - 4x -2y
Answer:
(-x-y)
Step-by-step explanation:
Given data
First expression = ( 3x + y)
Second expression = (-4x -2y)
Add the two expresssion
= ( 3x + y)+ (-4x -2y)
Open bracket
=3x+y-4x-2y

In \triangle LMN,△LMN, \angle N \cong \angle M,∠N≅∠M, LM = 14LM=14 and MN = 8MN=8. Find the length of NL.NL.
Answer:
11.5
Step-by-step explanation:
We solve using :
Pythagoras Theorem
LM² = MN² + NL²
NL² = LM² - MN²
NL = √LM² - MN²
NL = √14² - 8²
NL = √(132)
NL = 11.489125293
NL = 11.5
Therefore, the length of NL = 11.5
