The population of the city next year, after decreasing, will be 359,778
Here, we are given that the population of a city decreases by 1.7% per year.
This, means that the city's population will decrease by 1.7% in 1 year, (1.7 × 1.7)% in 2 years and so on.
The population of the city this year is given to be 366,000.
Thus, next year, the population will decrease by-
1.7% of 366,000
= 1.7/100 × 366,000
= 17/10 × 3,660
= 17 × 366
= 6,222
Thus, the city's total population next year will be-
366,000 - 6,222
= 3,59,778
Hence, the city's population to the nearest individual comes out to be 359,778.

The linear equation in point-slope form of a line with a slope of 23 and point (3,-2) is y = 23x - 71.
How to determine the equation of a line from a point and slope?The slope intercept formula is expressed as;
y = mx + b
Where m is the slope and b is the y-intercept.
Given the data in the question;
Slope m = 23Point: (3,-2)
x = 3y = -2Equation of line = ?First, use the the formula for the equation of line to determine the y-intercept 'b'.
y = mx + b
Plug in slope m = 23 and point (3,-2)
-2 = (23)3 + b
-2 = 69 + b
b = -2 - 69
b = -71
Now that we have both the slope m ( 23 ) and y-intercept b ( -71 ), plug these values into y = mx + b to find the linear equation.
y = mx + b
y = 23x + (-71)
y = 23x - 71
Therefore, the equation of the line is y = 23x - 71.

Write an Algebraic proof for the following
To prove this, we need to show that 2 is equal to x.
Given:
2(x + 5) - 3x = 7x - 6
Distribute:
2x + 10 - 3x = 7x - 6
Combine like terms:
-1x + 10 = 7x - 6
Add 1x to both sides of the equation:
10 = 8x - 6
Add 6 to both sides of the equation:
16 = 8x
Divide both sides of the equation by 8:
2 = x
Reflexive property:
x = 2

Find the slope of the line that passes through the following points: (4,-2) and (-4,-4)
The value of of slope of is 1/4.
How to calculate the value of the slope?It is possible to determine a line's direction and steepness by looking at its slope. Finding the slope of lines in a coordinate plane can aid in anticipating whether the lines are parallel, perpendicular, or none at all without actually using a compass.
Any two distinct places along the line can be used to determine the slope of any line. When two different places on a line are considered, the slope of a line formula compares the "vertical change" to the "horizontal change" in each case. The difference between the line's y and x coordinate changes is known as the slope of the line. Net changes in the y and x coordinates are as follows: y = y and x = x.
m = [tex]y_{2} - y_{1} /x_{2} x_{1}[/tex]
m = 1/4

Given,
f(x) = 1x + 12
expression to be in form of h
To find on the interval: [9, 9 + h]
∵ Average rate of change of f(x) on interval (a,b) is
A = f(b) - f(a) / b - a
⇒ f(9) = 1 x 9 + 12 = 21
⇒ f(9 + h) = 9 +h + 12 = 21 + h
⇒ f(b) - f(a) = 21 + h - 21 = h
⇒ (b-a) = 9 + h - 9 = h

Answer:
x=22
Step-by-step explanation:
Since a straight line is equal to 180 degrees,
(3x+3)+(5x+1) = 180
(3x+3)+(5x+1)-180=0
8x+4-180=0
8x-176=0
8x=176
x=176/8
x=22
Which also means that the first angle is (3(22)+3)=69 degrees
the second angle is (5(22)+1) = 111 degrees

GH
.
The numerical length of GH = 20 units
FH is a line segment.
G is a point on the line segment.
Then G divides the line segment FH into two line segments FG and GH.
We are given the lengths of FH, FG and GH in terms of x.
That is, FH=4x+8, FG=x and GH=5x
We need to find the numerical length of the line segment GH. We first need to find the x for this.
As G cuts the line segment FH into two parts, the length of the line segment FH is the sum of the lengths of the line segments FG and GH.
That is, FH = FG + GH
⇒ 4x+8 = x +5x
⇒ 4x+8 = 6x
