The population of town A is 4.5 times greater than the population of town B.
What is the power of a number?The power of a number describes how many times a number is multiplied by itself.
Given are the population of two towns A and B.
Town A has a population of 1.26×10⁵ and the population of town B is 2.8×10⁴.
To find how many times greater is the population of Town A than the population of Town B we have divide the population of town A by the population of town B which is,
= ( 1.26×10⁵)/(2.8×10⁴) times greater.
= (12.6)/(2.8). ( 10⁵ divided by 10⁴ is 10¹ which is 10)
= 4.5 times greater.

Which equation represents a line with a slope of 6 and a y-intercept of -5?
Answers
Answer: y=6x-5
Step-by-step explanation:
In the diagram below, find the value of y....
Answers
Answer:
y = 130
Step-by-step explanation:
(4x+8) + (3x-19) + (x+7) = 180
4x + 8 + 3x - 19 + x + 7 = 180
(4x + 3x + x) + (8 -19 + 7) = 180
8x - 4 = 180
8x -4 +4 = 180 +4
8x = 184
8x/8 = 184/8
x = 23
3(23) - 19 = 50
50 + y = 180
180 - 50 = y
y = 130

Arithmetic
Step-by-step explanation:
Since the common difference remains the same between terms, its arithmetic!
The first five terms of the given AP is 8, 20, 32, 44 ,56.
What is a sequence ?A sequence is a list of numbers written in form of a constant difference or ratio.
According to the given question the given question the first term (a₁) of the AP is 8 and the common difference (d) is 12.
This is an AP because given in the question it self of common difference.
We know than n term of an AP is aₙ = a₁ + (n-1)d.
Given,
a₁ = 8.
a₂ = 8 + (2-1)12
a₂ = 8 + 12
a₂ = 20.
Similarly.

What is the equation of a Line in Point-slope Form?Where, a and b are coordinates of a point on a line, and m is the slope, the equation of the line in point-slope form can be written as, y - b = m(x - a).
Given:
Slope of the line is: -2Point it passes through is: (4, 1).Therefore, substitute (a, b) = (4, 1) and m = -2 into y - b = m(x - a).
Thus:
y - 1 = -2(x - 4)
