If varies inversely as . It is known that = 10 when = 3, find the value of when = 5.
Answer:
y = 6
Step-by-step explanation:
If x varies inversely proportional as y.
[tex]x=\dfrac{k}{y}[/tex], k is constant of proportionality
or
k = xy
When x = 3 and y = 10
k = 3×10
k = 30
Put x = 5,
[tex]y=\dfrac{k}{x}\\\\y=\dfrac{30}{5}\\\\y=6[/tex]
So, the value of y is 6 when x is 5.

3x-2
Answer: 47
we have:
41° + 3x - 2 = 180°
⇔ 3x - 2 = 180 - 41
⇔ 3x - 2 = 139
⇔ 3x = 139 + 2
⇔ 3x = 141
⇔ x = 141/3
⇔ x = 47

An arithmetic sequence has this recursive formula:
a1=9
an=an-1 -3
What is the explicit formula for this sequence?
A. an=9+(n-1)(-3)
B. an=-3+(n-1)9
C. an=9+(n-3)(-1)
D. an=-1+(n-9)(-3)
Answer:
The correct answer is:
Option A. a_n=9+(n-1)(-3)
Step-by-step explanation:
Given that
a1 = 9
[tex]a_n = a_{n-1}-3[/tex]
We can see that in recursive formula the next term is being obtained by subtracting 3 from previous term
That means that the common difference is -3
We also know the first term
The general form of explicit formula for an arithmetic sequence is:
[tex]a_n = a_1 + (n-1)(d)[/tex]
We know that a1 = 9 and d = -3
Putting the values we get
[tex]a_n = 9+(n-1)(-3)[/tex]
Hence the correct answer is:
Option A. a_n=9+(n-1)(-3)

Write an equation of the line that passes through the pair of points. (0, 1), (5, 3)
Answer:
Step-by-step explanation:
(3 - 1)/(5 - 0)= 2/5
y - 1 = 2/5(x - 0)
y - 1 = 2/5x - 0
y = 2/5x + 1

5(5) -1 =24
so anything under that would equal fewer than 24
Is this what you're asking?
The population of a town is 132,00. The population increases 4% a year. What will be the population in 8 years?
9514 1404 393
Answer:
180,651
Step-by-step explanation:
Each year, the population is multiplied by the factor 1 + 4% = 1.04. After 8 years, it will have been multiplied by that factor 8 times. We indicate repeated multiplication like that using an exponent.
population in 8 years = 132,000 × 1.04^8 ≈ 180,651

Write an equation for the line that passes through the points (0, -2) and (-4, 0).
y = - x - 4
y = -2 x - 4
y = -2 x - 2
y = - x - 2
Answer:
y=-1/2x-2
Step-by-step explanation:
I dont think any of those options are the right one so thats the correct answer
Answer: y = -1/2x - 2
Step-by-step explanation:
To first write the equation, we need to find the slope and the y intercept and write it in the form y=mx +b
To find the slope, we will find the difference between the y coordinates and divide it by the difference between the x coordinates.
The y coordinates of the points are , 0 and -2
The x coordinates of the points are -4 and 0
0 - (-2) = 2
-4 -0 = -4
Slope: 2/-4 = -1/2
Now using the formula y=mx+b, you will input the slope and use one of the given point's coordinates to solve for b the y intercept.
We will use the point (0,-2)
-2 = -1/2(0) + b
-2 = b
This means the equation will be y = -1/2x - 2

solve for x
2(x - 2) + 3 = 2x - 1
9514 1404 393
Answer:
x can be any value (infinite number of solutions)
Step-by-step explanation:
The equation simplifies to ...
2(x -2) +3 = 2x -1
2x -4 +3 = 2x -1
2x -1 = 2x -1
This is true for every value of x. There are an infinite number of solutions.
