A function with the formula f(x) = ax + b, where a and b are real values, is referred to as a linear function.
The rate of change will be 3/4.
What is meant by linear function?A function with the formula f(x) = ax + b, where a and b are real values, is referred to as a linear function. Here, a stands for the line's gradient, and b for the y-axis intercept (which is sometimes called the vertical intercept).
The rate of change of y with respect to x, can be calculated utilizing any two of the pairs of values of the table, say, (3, -5) and (7, -2).
Rate of change [tex]$=\frac{y_2-y_1}{x_2-x_1}$[/tex]
Let, (3, -5) = (x1, y1) and (7, -2) = (x1, y1).
Rate of change [tex]$=\frac{(-5)-(-2)}{7-3}$[/tex]
Rate of change = 3/4.
Therefore, the correct answer is option c) 3/4.

Answers
Out of the given integer(s), {−3} is the integer which will make the inequality 5x + 12 > 2x + 6 false.
As per the question statement, we are supposed to determine which integer will make the inequality 5x + 12 > 2x + 6 false
Let's solve the inequality for range of x first,
5x + 12 > 2x + 6
5x - 2x > 6 - 12
3x > -6
x > -2
So for all values of x > -2, the inequality 5x + 12 > 2x + 6 is true and for all values of x < -2, the inequality 5x + 12 > 2x + 6 false.
And out of the given options only x = -3 < -2
Hence, we accept {−3} as our required integer.

An eighteen-acre building lot is five times as long as it is wide. What are its dimensions? [Note: 1 acre = 43,560 ft2.]
Answers
The dimensions of building lot are 396 feet width and 1980 feet length.
Let the width of building lot be x. So, the length of the same building lot will be 5x. According to the formula, the area will be length × width.
18 acre = x×5x
Keep the value of acre in the above mentioned relation
18 × 43,560 = 5x²
Performing multiplication on Left Hand Side of the equation
784,080 = 5x²
Performing division by 5
x² = 156,816
Now taking square root to find the value of x
x = ✓156,816
x = 396 ft
Thus, the width of building lot is 396 feet
The length of building lot = 5×396
Performing multiplication
The length of building lot = 1980 feet
Therefore, the length and width of building lot is 1980 feet and 396 feet respectively.

Thu has the same amount of money automatically deposited into a new savings account each week. After 2 weeks, she has $14. After 5 weeks, she has $35. The unit rate is measured in dollars per week. What is the constant of proportionality?
Answers
For the given data of saving account, unit rate is measured in dollars per week then constant of proportionality is equal to $7.
As given in the question,
For the saving account,
Amount deposited is directly proportional to the number of weeks
Let y be the amount deposited and x be the number of weeks
y ∝ x
y = kx
'k' is the constant of proportionality
As per data unit rate is measured in dollars per week
For y = $14 then x = 2 weeks
14 = 2k
⇒ k = $7
For y = $35 then x = 5weeks
35 =5k
⇒ k = $7
Therefore, for the given data of saving account, unit rate is measured in dollars per week then constant of proportionality is equal to $7.

Use the remainder theorem to find P (3) for P(x) = -x^4+3x^3-2x+3.

Answers
The most appropriate choice for remainder theorem will be given by-
Quotient = [tex]-x^3-2[/tex]
Remainder = -3
What is remainder theorem?
When f(x) is divided by (x-a), the remainder will be f(a).
If the remainder is zero, (x-a) will become a factor of f(x)
Expression to be divided is called dividend, expression by which dividend is divided is called divisor, expression obtained on division is called Quotient and the other part is the remainder.
There is also a well known formula
Divisor x Quotient + Remainder = Dividend
Here,
P(x) = [tex]-x^4 +3x^3 -2x+3[/tex]
P(3) = [tex]-(3)^4+3(3)^3-2(3)+3[/tex]

= -3
So by Remainder theorem, remainder is P(3)
So, Remainder = -3
Let the quotient be q(x)
divisor = [tex]x - 3[/tex]
We know,
Divisor x Quotient + Remainder = Dividend
[tex](x-3) \times q(x) +(-3) = -x^4 +3x^3 -2x+3\\(x-3) \times q(x) = -x^4 +3x^3 -2x+3 +3\\(x-3) \times q(x) = -x^4 +3x^3 -2x+6\\q(x) = \frac{-x^4 +3x^3 -2x+6}{x -3}\\q(x) =\frac{ -x^3(x-3)-2(x-3)}{x-3}\\q(x) = \frac{(x-3)(-x^3-2)}{x-3}\\q(x) = -x^3-2[/tex]

Answers
A minor treatment effect may nonetheless be significant under certain circumstances if the sample size is large and the sample variance is low.
What is the standard error, and sample size?The standard error calculates the discrepancy between a sample's estimate and the actual value for the population. Therefore, the standard error should be smaller the better. In fact, a standard error of zero or extremely close to it would indicate that the projected value and the actual value are identical.Sample size determination is the process of deciding how many observations or replicates to include in a statistical sample.

The midpoint of GH is M(3, 6). One endpoint is H(6, 5). Find the coordinates of the other endpoint G.
Answers
The coordinates of the endpoint G is (0, 7).
The midpoint of the coordinate is the centre point which can be calculated by finding the average. So, the relation representing the endpoints and midpoint is as follows -
Midpoint (x, y) = ([tex] x_{1}[/tex] + [tex] x_{2}[/tex]/2), ([tex] y_{1}[/tex] + [tex] y_{2}[/tex]/2)
Keep the value in mentioned formula to find the endpoint G, represented as [tex] x_{1}[/tex] and [tex] y_{1}[/tex].
(3, 6) = ([tex] x_{1}[/tex] + 6/2) ([tex] y_{1}[/tex] + 5/2)
Relating the x and y values -
x value :
3 = [tex] x_{1}[/tex] + 6/2
[tex] x_{1}[/tex] + 6 = 3×2
[tex] x_{1}[/tex] + 6 = 6
[tex] x_{1}[/tex] = 6 - 6
[tex] x_{1}[/tex] = 0
y value :
6 = [tex] y_{1}[/tex] + 5/2
[tex] y_{1}[/tex] + 5 = 6×2
[tex] y_{1}[/tex] + 5 = 12
[tex] y_{1}[/tex] = 12 - 5

Answers
The values of x and y that satisfy the equation (x+yi)+(4+9i)=9-4i is x = 5 and y = -13 .
In the question ,
the equation is given as
(x+yi)+(4+9i)=9-4i
to find the value of x and y , we solve LHS and RHS of the equation separately
So LHS =
(x+yi)+(4+9i)
x+yi+4+9i
Adding the real and imaginary terms , we get
(x+4)+(y+9)i which is equal to RHS that is 9-4i
So , on comparing , we get
x+4 = 9 and y+9 = -4
x= 9-4 and y = -4-9
x = 5 and y = -13
Therefore , the values of x and y that satisfy the equation (x+yi)+(4+9i)=9-4i is x = 5 and y = -13 .
