The comparison of the linear functions to line A are given as follows:
y = 4x ± constant: parallel.y = -x/4 ± constant: perpendicular.y = x/4 ± constant: neither parallel nor perpendicular.When are lines parallel, perpendicular or neither?A linear function is defined as follows:
y = mx + b.
In which the coefficients are listed as follows:
m is the slope.b is the intercept.The slope determines if the lines are parallel, perpendicular, or neither, as follows:
If the slopes for both lines are equal, the lines are parallel.If the multiplication of the slopes of both lines is of -1, they are perpendicular.Otherwise, they are neither.In this problem, the function is:
y = 4x - 6.
Hence the slope is of:
m = 4.
Then the functions, relative to y = 4x - 6, are classified as follows:
Parallel: slope of 4.Perpendicular: slope of -1/4, as 4 x (-1/4) = -1.Neither: any slope different of 4 and of -1/4.Missing InformationThe problem gives three lines with different slopes, and you have to define if they are parallel, perpendicular or neither parallel nor perpendicular.
The intercepts are not relevant and I couldn't find the problem on the internet, hence I say that they are constants.

What is mixed fraction?A fraction represented with its quotient and remainder is a mixed fraction. For example, 2 1/3 is a mixed fraction, where 2 is the quotient, 1 is the remainder. So, a mixed fraction is a combination of a whole number and a proper fraction.
Initial height of plant = 6 3/8 inches
Final height = 8 3/5 inches
Difference in height = 8 3/5 inches - 6 3/8 inches
converting the mixed fraction to improper fraction
8 3/5 = 43/5
6 3/8 = 51/8
43/5 - 51/8
multiply 43/5 by 8/8 and 51/8 by 5/5 so that both fractions have common denominator, it becomes
344/40 - 255/40
Collect only the numerator we have,
344- 255 = 89 which is no 89/40

A group entering a zoo purchased 32 admission tickets for a total of $148. Adult tickets cost $7. 50, and tickets for children cost $3. 50. How many of each type of ticket were purchased?.
23 tickets are purchased for children and 9 tickets are purchased for adults.
Given,
In the question:
A group entering a zoo purchased 32 admission tickets for a total of $148. Adult tickets cost $7. 50, and tickets for children cost $3. 50.
To find the how many of each type of ticket were purchased?
Now, According to the question:
It is given in the question that 32 tickets are purchased by group which cost total $148.
Let the number of children of the group who are entering the zoo be x. Then the number of adults will be 32- x
Now cost of one ticket for adult = $7.50
Total amount spent on adult tickets = 7.50 × (32-x)
Similarly, cost of one ticket for child= $3.50
Total amount spent on children tickets = 3.50 × x =3.5x
Total amount spent by group on tickets = $148
⇒ 7.5 × (32-x) + 3.5x = 148
⇒ 240 - 7.5x + 3.5x = 148
⇒ 7.5x - 3.5x = 240 - 148
⇒ 4x = 92
⇒ x = 23
Children = 23
Adults = 32-x = 32-23 = 9
Hence, 23 tickets are purchased for children and 9 tickets are purchased for adults.

Answer:
Yes, the town exceeded the average annual rainfall by 0.4 inchesStep-by-step explanation:
The average annual rainfall for a town is 43.2 inches.
This is converted to average monthly as:
43.2 in / 12 = 3.6 inThe difference is:
4 in - 3.6 in = 0.4 inAnswer:
Yeah, they exceeded by 0.4 inches.
Step-by-step explanation:
It is given that,
→ the average monthly rainfall for the previous 9 months was 4 inches.
The monthly rainfall in 12 months,
→ 43.2 inches ÷ 12 months
→ 43.2/12
→ 3.6 inches
Then the difference will be,
→ 4 inches - 3.6 inches
→ 4 - 3.6

a rectangular garden has a length that is six feet more than twice its width. it takes 120 feet of fencing to completely enclose the garden's area. write an equation that could be used to find the width of the garden. clearly define your variable.
Length (L) = 42
Width (W) = 18
and the equation which helps to find the width of the garden is
L = 6 + 2W
Now, we have to find the length and width of the garden area.
It is given that,
we know that the Length is 6 feet more than twice the width, this in other words, it means that:
L = 6 + 2W -------------------------(1)
So, let's denote W as X
The perimeter of the garden is 120 and the expression to calculate is:
P = 2W + 2L ------------------------(2)
Replacing all the values in the above expression we have the following:
120 = 2x + 2(6 + 2x) ---------------------(3)
Solving for x from the above equation (3), we have:
⇒120 = 2x + 12 + 4x
⇒120 - 12 = 6x
⇒108 = 6x
⇒x = 108/6
⇒ x = 18
So the Width is 18, therefore the Length from equation (1):
L = 6 + 2(18)
⇒L = 6 + 36
⇒L = 42

3. Quadrilateral SMAK is similar to quadrilateral DOWN. Assuming the length of SM is 34u and the length of DO is 17u, what is the ratio of AK to WN in simplest form?
1) the speed of Simon per hour is 128 miles/Hr
2) The length of IG is 20 Units.
3) The ratio of SM is 2:1
What is the explanation of the above answer?1) For 1, to obtain the speed of Simon per hour, all you need to do is multiply 32 x 4.
This is because in every hour, 15 minutes occurs four times. That is:
1 hour = 60 minutes
Hence, if 32 miles is done in 15 minutes, then 60 minutes =
32 x 4
= 128 miles
Hence the speed of Simon per hour is 128 Miles/ Hour
2) Given that the two triangles are identical, it means that on the basis on RHS theorem we have been given all the sides. Note that BG is 6 Units (we are assuming that this is the base) , then AT from the other triangle (see attached) is 20.
We assume this is the Hypotenuse. CT is also given. We assume this is the height. If we have CT and AT, and both triangles are the same, then IG is 20 units.
3) For the quadrilateral, recall that in quadrilaterals opposite sides are equal. If one side is 34u on one, and the other side is 17u on the other quadrilateral, then we already have the measure of the sides for both quadrilaterals.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics. The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.Uniform distribution
a = 0
b = 10
a) P(friend is between 25 and 30 minutes late) = (30 - 25)/(b - a)
