Answer:
y = -x - 4
Step-by-step explanation:
Given line: y = x - 1
Slope of given line = 1
The slopes of perpendicular lines are negative reciprocals, so the slope of the perpendicular line is -1.
slope = -1
point: (-6, 2)
y = mx + b
y = -x + b
2 = -(-6) + b
2 = 6 + b
b = -4
Equation:
y = -x - 4

A meenger earn #2,640 per year and pay tax at the rate of 10k on a naira. How much tax doe he pay in a year
264 naira tax doe he pays in a year.
Amount earned per year = 2460
Rate of interest paid: 10k per naira earned
Tax paid by messenger per year :
100k = 1 naira
10k = (100/10) = 0.1 naira
Hence 0.1 naira is paid as tax on every naira earned
The total amount paid off is 2640 Naira :
Amount paid per naira * total amount earned
(0.1 * 2640) = 264 nairas.
A tax is a compulsory monetary charge or a few other sorts of levy imposed on a taxpayer (a man or woman or criminal entity) by using a governmental agency if you want to fund authorities' spending and numerous public expenses (regional, neighborhood, or countrywide), and tax compliance refers to coverage movements and character behavior geared toward making sure that taxpayers are paying the right amount of tax on the proper time and securing the right tax allowances and tax reliefs. the first known taxation passed off in historical Egypt around 3000–2800 BC. A failure to pay in a well-timed way (non-compliance), together with evasion of or resistance to taxation, is punishable by means of regulation. Taxes consist of direct or oblique taxes and may be paid in cash or as its labor equivalent.

Construct a polynomial function with the stated properties. Reduce all fractions to lowest terms.
Third-degree, with zeros of −3, −1, and 4, and a y-intercept of −13.
The third degree polynomial function with zeros of −3, −1, and 4, and a y-intercept of −13 is y = -13/12 (x³ - 13x + 12)
Polynomial function:
polynomial function refers a functions of single independent variables, in which variables can occur more than once, raised to an integer power.
Given,
Third-degree, with zeros of −3, −1, and 4, and a y-intercept of −13.
Here we need to construct a polynomial function with the stated properties and reduce all fractions to lowest terms.
The standard form for the third degree polynomial function is written as,
y = K (x + zero1) (x + zero2) (x + zero3)
Here we know the values of zeros as -3, -1 and -4.
Apply it on the general form,
y = K (x -3) (x - 1) (x + 4) ----------------------(1)
And the value of y intercept is -13 then the value of x is 0.
So, it can be written as,
-13 = K(0 - 3) (0 - 1) (0 + 4)
-13 = K (-3)(-1)(4)
-13 = K (12)
K = -13/12
Now, we have to apply these value on the equation (1), then we get,
y = -13/12 (x -3) (x - 1) (x + 4)
When we expand these, then we get the polynomial function as,
y = -13/12 (x³ - 13x + 12)

What is the Centroid Theorem?The centroid theorem states that the distance from the centroid of the triangle to the opposite vertex is equal to one-third of the length of the segment that connects the midpoint of a side of a triangle to the opposite vertex.
Given:
AM = 44, CE = 54, and DM = 23, where M is the centroid of the triangle, thus:
FM = 1/3(FA) = 1/3(AM + FM)
Substitute
FM = 1/3(44 + FM)
3FM = 44 + FM
3FM - FM = 44
2FM = 44
FM = 44/2
FM = 22
A.F = AM + FM = 44 + 22
A.F = 66
CM = 2/3(CE)
CM = 2/3(54)
CM = 36
ME = CE - CM = 54 - 36
ME = 18
MB = 2/3(DB) = 2/3(DM + MB)
MB = 2/3(23 + MB)

a fair die with its faces numbered from 1 to 6 will be rolled. which of the following is the best interpretation of the probability that the number landing face up will be less than 3 ?
When a fair die with faces numbered 1 to 6, the probability that the number landing face up is less than 3 is 1/3.
The probability measures how likely an event to occur. The probability of an event A is defined as:
P(A) = number of ways that event A can occur / all possible outcomes
In the given problem, let x be any number of die's face, then
number of ways x will show up = 1
all possible outcomes = 6
Hence,
P(x) = 1/6
Numbers that are less than 3 is 1 and 3. Therefore,
P (x<3) = P(1) + P(2)
P (x<3) = 1/6 + 1/6 = 2/6 = 1/3
Therefore, we can conclude that the probability that the number landing face up is less than 3 is 1/3

To solve the following inequality for x.

Since there is no x in this I'm assuming we are looking for z
Step 1: Simplify both sides
15r - 26 > -13z + 2
Step 2: Add 13z to both sides
15r - 26 + 13z > -13z + 2 + 13z
28 - 26 > 2
Step 3: Add 26 on both sides
28 - 26 + 26 > 2 + 26
28z > 28

using the ":" to separate example valuesusing the "/" to separate one value from the totalas a decimal, after dividing one value by the totalas a percentage, after dividing one value by the totalIt was given that Alice, Ben and Charlie are to share $213.
Ratio of Alice's share to Ben = 4 : 3
Ratio of Ben's share to Charlie = 8 : 5
Combining these ratios, their shared item (Ben's share) must be the same in each ratio.
Taking Alice's share to Ben, 4 : 3 and multiplying both parts by 8 to get an equivalent ratio, we have:
Alice : Ben = 4(8) : 3(8) = 32 : 24
Likewise, taking Ben's share to Charlie, 8 : 5 and multiplying both parts by 3, we have:
Ben : Charlie = 8(3) : 5(3) = 24 : 15
Combining these ratios, we have:
Alice : Ben : Charlie = 32 : 24 : 15
Adding the ratios together, we have: 32 + 24 + 15 = 71

The formula for the transformation of a function, f(x) is y = a·f(b·(x + c)) + d
Where;
a indicates the graph of the function is dilated vertically
b indicates a dilation horizontally
c indicates a translation horizontally
d indicates a vertical translation
The transformation applied to the parent function is the f(x) is an addition of a term, d = 3, which is a vertical translation
In a vertical translation of the form f(x) ± d
When d > 0, the graph of f(x) is moved up d units to get the graph of f(x) + d
When d < 0, the graph of f(x) is moved down d units to get f(x) - d
The graph of y = |x| + 3, obtained from the parent function, y = |x|, by a transformation of d = +3, therefore, the graph of y = |x| is moved up 3 units to get the graph of y = |x| + 3
