Answer:
After 7 months months the population of both the town will be equal.
Step-by-step explanation:
Let's assume, the population of both towns will be equal after x number of months.
Every month 125 people move out of the town and 200 people move into the town, where already 43,425 people are living. So, the population of the former town after x months is,
Every month 150 people move out of the town, where already 45,000 people are living. So, the population of the latter town after x months is,
when the population of both of the towns are same,then

If a = 3 and b = -1, find the value of the following expression.
Answer:
The required answer is 54.
Step-by-step explanation:
Given that a = 3 and b = (-1) . And we have to find the value of 2a³ b⁴ .
In such kind of problems , just substitute the given values of a and b to get the required answer .
So here ,
= 2a³ b⁴.
= 2 × (3)³ × (-1)⁴.
= 2 × 27 × 1 .
= 54

(9,65)
(2, 10)
(8,65)
(3, 35)
Answer:(8,65)
Step-by-step explanation:
Because if you were to write this as an equation it would be 25+5x=y than you plug in each variables until determined true.
Which one is the right answer?
Answer:
D
Step-by-step explanation:
First of all, i mean A and B are out first thing because you don't have enough information to find out if it's true.
C is incorrect because as stated before, not enough information.
However,
You know that the angles 1-8 are all supplementary, which means that 1 and 2 can be added to make 180 degrees, as so can 3 and 4, 3 and 1. 2 and 4, blah blah blah.
In D, the angles that are being added are supplementary, because the three lines making up that weird figure is adjacent and is parallel to each other.
If you give one of the angles a degree, you know that 180-x with x being that degree, will equal the other angle on the other side of the lines.
Therefore its D.
Edit:
I just realized that theres an angle stated at the top of the screen. Still with that angle given, A and B is incorrect and the answer is still D.

Can someone please explain to me how to work this out?
Answer:
B
Step-by-step explanation:
the way i work it out is if you take the product and power it to the third you can easily find out which answer is correct. another way, if you don't have a calculator is to look at the last digit in the number in the square root sign.
For example, 3 square root 64 equals 8. you would look at the 4 and try to find 3 numbers that end in 4 OR is divisible three times by the number. 64 is exactly divisible by 4 only 3 times so you know that it can't be 8.
hope this helps!

7(7 + 5r) = 7(2 + 6r) please show work
Answer:
r=5
Step-by-step explanation:
1. Use the division property
49+35r=14+42r
2. Combine like terms
35=7r
3. Divide
r=5
Answer:
r = 0
Step-by-step explanation:
7 ( 7 + 5r ) = 7 ( 7 + 6r )
First use the ditributive property of multiplication -
49 + 35r = 49 + 42r
Subtract 35r from both sides -
49 = 49 + 7r
Subtract 49 from both sides -
0 = 7r
r = 0

how many solutions does 12x + 1 = 12x - 10
Answer:
No solutions
Step-by-step explanation:
First things first we need to get rid of the variables so we subtract -12x from one side to the other.
Now we have 1= -10
In this case, 1 is not equal to -10 so we get no solutions!
(Side note: if they were the same like 3=3 that would be all solutions.)

Grayson is behind on his retirement savings and wants to start saving $1,000 per month so he can retire in 20 years. If he earns 9% a year, compounded monthly, how much money will Grayson have to retire? $622,447 $667,887 $684,254 $724,333
If Grayson begins saving $1,000 per month and makes 9% a year, compounded monthly, he will have $667,887 in retirement. Therefore, $667,887 is the correct number.
Future Value: What Is It?A financial notion known as future value (FV) gives a worth to an asset based on anticipated factors like future interest rates and cashflows. Knowing how much their money might be in five years, given an anticipated rate of return, may be helpful for an investor. Future value is the idea of taking the investment's current worth, adding anticipated development, and estimating what the investment is going to cost in the future.
To calculate the amount of money Grayson will have at retirement, we can use the formula for the future value of an annuity:
FV = Pmt x (((1 + r/n)^(n*t)) - 1) / (r/n)
where:
FV is the future value of the annuity (i.e., the amount Grayson will have at retirement)
Pmt is the monthly payment ($1,000 in this case)
r is the annual interest rate (9% in this case)
The number of annual increasing times is n. (12 for monthly compounding)
t is the number of years (20 in this case)
Plugging in the numbers, we get:
FV = 1000 x (((1 + 0.09/12)⁽¹²*²⁰⁾) - 1) / (0.09/12)
FV = $667,887.20
Therefore, Grayson will have $667,887 at retirement if he starts saving $1,000 per month and earns 9% a year, compounded monthly. Therefore, the answer is $667,887.

M = 2/3, B = -5
M = -5, b = 3/2
M = 2, b = -6
M = -5, b= 2
Answer: m = 3/2, b = -5
Step-by-step explanation:
When we input these values into slope-intercept form y = mx + b, then we get y = 3/2x -5. When trying out different x values, we get the same points that are on the line such as (2, -2) also the y-intercept is -5, so we know it is a true statement and that the slope 3/2 and y-intercept -5 are the only correct answers for this line.
Name the line of reflection used to map each pre-image to its image.
Please help
Answer:
Step-by-step explanation:
From the picture attached,
9). When pre-image KLMN is a reflected across x = -2, we get image K'L'M'N'.
Therefore, line of reflection will be x = -2
10). In this picture line of reflection which passes through origin (0, 0) and slope = 1 will be,
y = x.
11). Since, all the points of image and preimage points are equidistant from x-axis, line of reflection will be x-axis or y = 0.
12). Line passing through midpoint of the line joining BB' will be the line of reflection.
Coordinates of B → (5, 3)
Coordinates of B' → (5, 7)
Coordinates of BB' → [tex](\frac{5+5}{2},\frac{3+7}{2})[/tex] → (5, 5)
Therefore, line of reflection will be y = 5.
13). Coordinates of G → (2, 5)
Coordinates of G' → (-2, 5)
Midpoint joining the segment GG' → [tex](\frac{2-2}{2},\frac{5+5}{2})[/tex] → (0, 5)
Therefore, line of reflection → x = 0
14). Line of reflection passing through (0, 0) and slope = -1
y = -x
write the equation of the line perpendicular to y= 5/2x+3 that passes through the point (-7,9). Type an answer using slope-intercept form or using the given points in point-slope form
Answer:
5y = -2x + 31
Step-by-step explanation:
Given equation:
y = [tex]\frac{5}{2} x + 3[/tex]
Coordinate = (-7,9)
Unknown:
Equation of the line perpendicular = ?
Solution:
The slope - intercept format of a line is given as;
y = mx + c
where y and x are the coordinates
m is the slope
c is the y-intercept
y = [tex]\frac{5}{2} x + 3[/tex]
From the given equation; slope is [tex]\frac{5}{2}[/tex]
A line perpendicular will have a slope that is negative and the inverse of this;
slope of perpendicular line = [tex]-\frac{2}{5}[/tex]
Since y= 9 and x = -7;
So;
9 = [tex]\frac{-2}{5} x (-7)[/tex] + C
9 = [tex]\frac{14}{5}[/tex] + C
C = 9 - [tex]\frac{14}{5}[/tex] = [tex]\frac{31}{5}[/tex]
Now,
y = [tex]-\frac{2}{5}[/tex]x + [tex]\frac{31}{5}[/tex]
mulitply through by 5;

Simplify (1/7) to the 2 power
Answer:
ill pass
Step-by-step explanation:
The statement as (1/7) to the 2 power is equivalent to 1/49.
What is Expression?
An expression in math is a sentence with a minimum of two numbers/variables and at least one math operation in it. Examples -
2x + 3y
3x + 5y + z
Given is a statement as (1/7) to the 2 power.
We have the given statement -
"(1/7) to the 2 power".
We can write it as -
[X] = (1/7)²
[X] = 1/7 x 1/7
[X] = 1/49
Therefore, the statement as (1/7) to the 2 power is equivalent to 1/49
