What are linear equations?Linear equations help in representing the relationship between variables such as x, y, and z, and are expressed in exponents of one degree. In these linear equations, we use algebra, starting from the basics such as the addition and subtraction of algebraic expressions.
Given here: Two T-shirt brands Initial me and monogram mania
Clearly from the graph we can observe that the slope of monogram is not as steep as initial me which indicates that Monogram Mania charges less per T-shirt printed than Initial Me charges.
Hence, The answer is Monogram Mania charges less per T-shirt printed than Initial Me charges.

You make six posters to hold up at a basketball game. Each poster has a letter of the word TIGERS You and five friends sit next to each other in a rowe
The posters are distributed at random. Find the probability that TIGERS is spelled correctly when you hold up the posters
Answer:
1/720
Step-by-step explanation:
there is only one way to spell tiger but there's 720 outcomes of the other words you can make
The probability that TIGERS is spelled correctly when you hold up the posters is 0.00139 approximately or 1/720 exactly.
How to calculate the probability of an event?Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.
Then, suppose we want to find the probability of an event E.
Then, its probability is given as
[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}[/tex]
where favorable cases are those elementary events who belong to E, and total cases are the size of the sample space.
For this case, the letters of TIGERS are given at random.
All the six letters are different and there exist 6! permutations for them. (as for n unique things, there exist n! possible arrangements of theirs).
So, the posters can be distributed in 6! = 6×5×4×3×2×1 = 720 ways.
Out of those 720 ways, there is only one correct way to spell TIGERS correctly.
Thus, we get:
P(event that correct order of posters is distributed) = [tex]\dfrac{1}{720} \approx 0.00139[/tex]
Thus, the probability that TIGERS is spelled correctly when you hold up the posters is 0.00139 approximately or 1/720 exactly.

What is the equation of the line in slope-intercept form?
Answer:
The equation of the line in slope-intercept form is:
y = x + 4
Step-by-step explanation:
The slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptGiven the points on the line graph
(0, 4)(1, 5)Determining the slope between (0, 4) and (1, 5)
(x₁, y₁) = (0, 4)
(x₂, y₂) = (1, 5)
Using the formula
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [5 - 4] / [1 - 0]
= 1 / 1
= 1
Thus, the slope of the line = m = 1
We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.
From the graph, it is clear
at x = 0, y = 4
Thus, the y-intercept b = 4
now substituting b = 4 and m = 1 in the slope-intercept form
y = mx + b
y = (1)x + 4
y = x + 4
Therefore, the the equation of the line in slope-intercept form is:
y = x + 4

Two points, a and b, are graphed on the number line below. Maynard says there is not
enough information to write an inequality statement comparing a and b. Which statement
explains whether or not Maynard is correct?
Answer:b
Step-by-step explanation:
Maynard is incorrect on the number line a is to the left of b thus a < b can be represented thus option (A) is correct.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.
As per the given number line,
If a number is going to the left of a number line then it will become lower and lower.
Since a is on the left of b so a < b.
It is also obtained that a is less than 0 so it will be negative while b will be positive since all negative value is less than positive thus a < b will be correct.
Hence "Maynard is mistaken since an is to the left of b on the number line, which can be expressed as a b".

The midline is y=
The amplitude is
The period is
Answer:
The midline is y=-1
Amplitude = 3
The period is 2 units
Step-by-step explanation:
Sinusoidal Function
It refers to a mathematical curve with a smooth and periodic oscillation. Its name comes from the sine function but it can be a cosine function too. They only differ by the phase angle of 90 degrees or π/2 radians.
The amplitude is half the distance from the maximum and the minimum points. The graph shows a sinusoid with a maximum value of y=2 and a minimum value of y=-4.
The amplitude is:
[tex]A=\frac{2+4}{2}=3[/tex]
Amplitude = 3
The midline is the distance from the center of the sinusoid to the x-axis. It's also called the vertical shift.
The midline can be found by subtracting the amplitude A=3 to the maximum value M=2:
ML = 2 - 3 = -1
It can also be found by adding the amplitude to the minimum value:
ML = -4 + 3 = -1
The midline is y=-1
The period is the time the wave takes to complete a full cycle. We only have to focus at any point on the wave (xo,yo) and find the next value of x where the sinusoid has the very same behavior (x1,y1). The period is then x1-x0.
We find at x=0, y=-1 and it's moving up. At x=1 it has the same value but it goes down, so the wave is at its half cycle. At x=2 it repeats the same behavior as for x=0. Thus:
The period is 2 units

Answer:
Some of your pic is cut off so it's difficult to give the exact answer. But if you plot the points from the table you get that the equation for that set of data is linear and is y = 1/3x -2. This tells me that the y-intercepts are the same for both equations, so your answer is not the first or the third. Because the slope of the function A is 3 and for B is 1/3, the line for function A is steeper, the second of your choices above.
