Answer:
y = 3/4 x - 1
Step-by-step explanation:
We can use the point-slope form of the equation of a line.
y - y_1 = (y_2 - y_1)/(x_2 - x_1)(x - x_1)
y - (-4) = (5 - (-4))/(8 - (-4))(x - (-4))
y + 4 = (9/12)(x + 4)
y + 4 = (3/4)(x + 4)
y + 4 = (3/4)x + 3
y = (3/4)x - 1

Find the volume of a cube that has a total surface area of 54 square millimeters.
The volume of a cube that has a total surface area of 54 square millimeters is 27 cubic millimeters
How to determine the volume?The surface area is given as
A = 54
This is calculated using
A = 6L^2
So, we have
6L^2 = 54
Divide
L^2 = 9
This gives
L = 3
The volume is
V = L^3
This gives
V = 3^3
Evaluate
V = 27
Hence, the volume of a cube that has a total surface area of 54 square millimeters is 27 cubic millimeters

Using a proportional relationship, the amounts are given as follows:
Tennis 3, Soccer 7.Tennis 36, Soccer 84.What is a proportional relationship?A proportional relationship is a function in which the output variable is given by the input variable multiplied by a constant of proportionality, that is:
y = kx
In which k is the constant of proportionality.
For this problem, we have that:
The input variable is the number of tennis players.The output variable is the number of soccer players.From the first row of the table, the constant is given as follows:
k = 35/15 = 7/3.
Hence the relationship is:
y = 7/3x.
For the second row of the table, we have that x = 3, hence:
y = 7/3 x 3 = 7.
For the third row of the table, we have that y = 84, hence:
84 = 7/3x
x = 84 x 3/7
x = 36.

The width of a rectangle is the length minus 5 units. The area of the rectangle is 24
units. What is the length, in units, of the rectangle?
Answer:
L = 8
w = 3
Step-by-step explanation:
Givens
w = L - 5
L = x
Area = 24
Formula
Area = L * w
Solution
Area = (x) * (x - 5)
24 = x * (x - 5) Remove the brackets
24 = x^2 - 5x Subtract 24 from both sides
0 = x^2 - 5x - 24 This will factor
0 = (x - 8)(x + 3)
x + 3 is an extraneous root. You cannot have a length of -3 units no matter what the units are.
x - 8 = 0
x = 8
Answer
The length = 8
The width is = 8 - 5 = 3
Based on the what we established about the classification of y and using the closure of integers, what does the equation tell you about the type of numbers y must be for the product to be rational? What conclusion can you now make about the result of multiplying a rational and an irrational number
The statements are:
x . y = m/n
substituting the values.
a/b . y = m/n
multiplication property of equality.
b/a . a.b . y = m/n . b/a
simplify.
y = mb/na
The product of a rational number with an irrational number is an irrational number. To see this assume that x is a rational number and y an irrational number. Then let us assume that the product xy is rational, which means that there are integers a,b such that xy=a/b. But then we obtain y=(1/x)(a/b) which is also rational since the set of rational numbers is closed under multiplication. But this is a contradiction since y was assumed to be an irrational number.
Hence we made the required conclusion.

The third term of the arithmetic sequence is 18.
How to solve arithmetic sequence?The arithmetic sequence formula can be represented as follows:
nth term = a + (n - 1)d
where
a = first termd = common differencen = number of termsTherefore, 4 numbers are inserted between 4 and 39.
Hence,
a = 4
39 = 4 + 5d

A data set's mean (average) is calculated by summing all of the numbers in the set, then dividing by the total number of values in the set. When a data collection is ranked from least to greatest, the median is the midpoint. The number that appears most frequently in a data collection is called the mode.
The median is computed by sorting the scores into numerical order, dividing the total by 2, rounding the result up if the number of scores is odd to determine the median position, or by averaging the median position and the position after it, if the number of scores is even.
