Only the one on the bottom right is a function. It's the only one that does not have 2 of the same x value for a single y value.
Suppose you know that ∠S and ∠Y are complementary, and that m∠S = 4(m∠Y) − 135°. Find m∠Y.
Answer:The value of angle y is 40°.
Complementary angles are the angles that have their sum equal to 90°.
Therefore, based on the information given, the value of angle y will be calculated thus:
x + y = 90°.
4y - 110° + y = 90°
Collect like terms
4y + y = 90° + 110°
5y = 200°
y = 200/5

An equation of the line of best fit (trend line) is y = 0.19x + 308.93.
The estimated attendance for the year 2005 is approximately equal to 336 people.
How to determine an equation of the line of best fit for the data set?In order to determine an equation for the line of best fit (trend line) that models the data points contained in the table, we would have to use a graphing calculator (scatter plot).
In this scenario, the number of years would be plotted on the x-axis of the scatter plot while the number of attendance would be plotted on the y-axis of the scatter plot.
Based on the scatter plot (see attachment) which models the relationship between the number of years and attendance, an equation for the line of best fit is given by:
y = 5.43x + 254.42
Lastly, we would determine the predicted attendance for the year 2005:
Years, t = 2005 - 1990 = 15 years.

Straight Line Graphs Question. I tried to solve the section (a) part of the question correctly I followed the gradient method plugging in the values and got [tex]y = \frac{1}{6} x + 1.6 (recurring). However the answer is y = \frac{1}{2} x + 3.[/tex]. Where am I going wrong? Can someone explain step by step how to solve this please.
The equation of the straight line joining A to B is y = (1/2)x + 3, the equation of the straight line joining B to C is y = (1/2)x + 3, and A, B, and C are collinear.
What are collinear points?
Collinear points are three or more points that lie on the same straight line. In other words, if three points A, B, and C are collinear, then there exists a straight line that passes through all three points. To determine if three or more points are collinear, we can find the slope of the line that passes through any two of the points. If the slope is the same for all possible pairs of points, then the points are collinear. Otherwise, they are not collinear.
a) To find the equation of the straight line joining A to B, we can use the slope-intercept form of the equation of a line:
y = mx + b
where m is the slope of the line, and b is the y-intercept.
The slope of the line passing through A and B is:
m = (y₂ - y₁) / (x₂ - x₁)
where (x₁, y₁) = (-8, -1) and (x₂, y₂) = (-4, 1).
m = (1 - (-1)) / (-4 - (-8)) = 2/4 = 1/2
To find the y-intercept, we can use the point-slope form of the equation of a line:
y - y₁ = m(x - x₁)
where (x₁, y₁) = (-8, -1) and m = 1/2.
y - (-1) = (1/2)(x - (-8))
y + 1 = (1/2)(x + 8)
y = (1/2)x + 3
Therefore, the equation of the straight line joining A to B is y = (1/2)x + 3.
b) To find the equation of the straight line joining B to C, we can use the same method:
m = (y₂ - y₁) / (x₂ - x₁)
where (x₁, y₁) = (-4, 1) and (x₂, y₂) = (12, 9).
m = (9 - 1) / (12 - (-4)) = 8/16 = 1/2
Using point-slope form with the point (x₁, y₁) = (-4, 1) and slope m = 1/2:
y - 1 = (1/2)(x - (-4))
y - 1 = (1/2)x + 2
y = (1/2)x + 3
Therefore, the equation of the straight line joining B to C is y = (1/2)x + 3.
c) From the equations of the lines joining A to B and B to C, we can see that both lines have the same slope of 1/2. This implies that the three points A, B, and C are collinear, i.e., they lie on the same straight line.

How does angle opposite to a side of triangle affect its size?
If the angle facing a side of a triangle increases, then the length of the opposite side may also increase. This is because the larger the angle, the more vertical the opposite side becomes, and therefore the longer it may become.
Conversely, if the angle facing a side of a triangle decreases, then the length of the opposite side may also decrease. This is because the smaller the angle, the less vertical the opposite side becomes, and therefore the shorter it may become.

Answer:
$1007.03
Step-by-step explanation:
You want the cost of copies for the month at 1 1/3 cents each if the copy counter ran from 6583 to 82110 during the month.
Number of copiesThe number of copies made is the difference in counter readings:
82110 -6583 = 75,527 . . . . . copies made
CostEach costs 1 1/3 = 4/3 cents, so the cost of these copies is ...
(75,527 copies) × (4/3 cents/copy) = 100702 2/3 cents ≈ 100703 cents
There are 100 cents in a dollar (or other currency unit), so the cost is about ...

Answer: Buckle up this answer is gonna be a rollercoaster and here we go.
To find f.g, we first need to evaluate g(-4) and then use the result as the input for f(x).
We have:
g(-4) = -(-4)^2 + 2 = -16 + 2 = -14
Now, we use this result as the input for f(x):
f(g(-4)) = f(-14) = -14 - 8 = -22

After calculating the straight angle we know that ∠BAC is (A) 150°.
What is the straight angle?
A straight angle in geometry is one that is 180 degrees in length.
It looks like a straight line, which is why it is known as a straight angle.
In other words, it is an angle whose sides are in the same straight line but opposite to the vertex.
A straight angle in geometry is an angle with a vertex point that is at 180 degrees.
In other words, an angle becomes a straight angle when its arms point in the opposite direction.
So, we know that s straight angle is always 180°.
∠BAD is a straight angle.
We can also observe that:
∠BAD = ∠BAC + ∠CAD
Now, solve as follows:
∠BAD = ∠BAC + ∠CAD
180 = ∠BAC + 50
180 - 50 = ∠BAC
130° = ∠BAC
Therefore, after calculating the straight angle we know that ∠BAC is (A) 150°.
