The required slope (m) is -12 when the points given are (-3, 4) and (-3, -8).
What is the slope?In mathematics, a line's slope, also known as its gradient, is a mathematical expression of the line's steep slopes and orientation.
A line's steeper can be identified by looking at its slope.
The slope was calculated mathematically as "rise over run" (change in y divided by change in x).
So, the slope formula is:
m = y2 - y1/x2 - x1
Now, substitute the values and calculate the slope as follows:
m = y2 - y1/x2 - x1
m = -8 -4/-3+3
m = -12/0
m = -12
Therefore, the required slope (m) is -12 when the points given are (-3, 4) and (-3, -8).

The price of a home (in thousands of dollars) is associated with the number of square feet in a home. Home prices in Smavile can be modeled using the equation p = 150 + 0.041a where p is the price of the home in thousands of dollars and a is the area of the house in square feet Home prices in Fancyville can be modeled using the equation p = 250 + 0.198a Ngoc saw a real estate advertisement for a 2800 square foot home that was selling for $280,000. Which city should she predict that the home is in?
Ngoc should predict that the home is located in Smavile based on the real estate advertisement
How to determine the city she should predict that the home is in?From the question, we have the following parameters that can be used in our computation:
Function 1: p = 150 + 0.041a (Smavile)
Function 2: p = 250 + 0.198a (Fancyville )
Where
a = area
p = price
From the question, we have
a = area = 2800
p = price = 280000
Using the above as a guide, we have the following:
So, we have
Function 1: p = 150 + 0.041 * 2800 (Smavile)
Evaluate the expression
p = 264.8 -- false
Function 2: p = 250 + 0.198 * 2800 (Fancyville )
Evaluate the expression
p = 804.4 --- false
264.8 is closer to 280 than 804.4
Hence, the home is in Smavile

a) The co-efficient of x⁴y³ = -241920
b) The coefficient of x²y⁷ = 900
What Does an Expression Coefficient Mean?
A coefficient is an integer that is either multiplied by the variable it is associated with or written alongside the variable. A coefficient is, in other words, the numerical factor of a term that contains both constants and variables. For instance, the coefficient in the expression 2x is 2.The expansion is given by the following formula:
(a + b)ⁿ = Σⁿₓ=₀(ⁿₓ) aⁿ⁻ˣ bˣ, where
(ⁿₓ) = n! / (n-x)! k! and n! = 1.2..3.....n.
a) (-3x+4y)⁷ = ⁷C₀ (-3x)⁷(4y)⁰ + ⁷C₁ (-3x)⁶(4y)¹ + ⁷C₂ (-3x)⁵(4y)¹ + ⁷C₃ (-3x)⁴(4y)³ + ⁷C₄ (-3x)³(4y)⁴ + ⁷C₅ (-3x)²(4y)⁵ + ⁷C₆ (-3x)¹(4y)⁶ + ⁷C₇ (-3x)⁰(4y)⁷
The co-efficient of x⁴y³ = 35x - 27x³ * 256y⁴
= -241920x³y⁴
Hence, the coefficient of x⁴y³ = -241920.
b) (5x - y)⁹ = ⁹C₀(5x)⁹(-y)⁰ + ⁹C₁(5x)⁸(-y)¹ + ⁹C₂(5x)⁷(-y)² + ⁹C₃(5x)⁶(-y)³ + ⁹C₄(5x)⁵(-y)⁴ + ⁹C₅(5x)⁴(-y)⁵ + ⁹C₆(5x)³(-y)⁶ + ⁹C₇(5x)²(-y)⁷ + ⁹C₈(5x)(-y)⁸ + ⁹C₉(5x)⁰(-y)⁹
The coefficient of x²y⁷ = 36 * 25x² * y⁷
= 900x²y⁷
Hence, the coefficient of x²y⁷ = 900.

Write your answer using integers, proper fractions, and improper fractions in simplest form.
The equation of the line passing through the points (0, -6) and (7, 4) in slope-intercept form is y = [tex]\frac{10}{7}[/tex]x - 6.
What is Slope?Slope of a line is defined as the tangent of the angle that the line makes with X axis.
Slope, usually denoted by 'm' of a line passing through two points (x₁, y₁) and (x₂, y₂) is given by,
m = (y₂ - y₁) / (x₂ - x₁)
The equation of a line in slope-intercept form is y = mx + b, where b is y intercept and m is the slope.
Here, we have two points (0, -6) and (7, 4).
m = (4 - -6) / (7 - 0) = 10/7
y intercept is the y coordinate of the point where the line touches with the Y axis. x coordinate will be zero there.
We already have such point (0, -6).
So b = -6
Substituting these in slope-intercept form,
y = [tex]\frac{10}{7}[/tex]x - 6
Hence, the equation of the given line in slope intercept form is y = [tex]\frac{10}{7}[/tex]x - 6.

Answer: C. 20
Step-by-step explanation:
Ley y be the duck mass, and x be the number of weeks
Our equation will be
y = 0.042x + 0.05
Then we plug 0.89 in the y
0.89 = 0.042x + 0.05
0.84 = 0.042x
x = 20 Weeks

What is the translation?A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.
Given that,
The coordinates of triangle ABC are A(-3, 1), B(-1, 2) and C(1, 1)
The coordinates of triangle A'B'C' are A'(0, 3), B'(2, 4) and (4, 3).
When the shape is moved towards the right by k units, then replace x with x + k.
When the shape is moved up by k units, then replace y with y + k.
A(-3, 1)→A'(-3+3, 1+2)

Polynomial division;
Divide the first term of the dividend by the first term of the divisor to divide polynomials using long division. The quotient's initial term is this. Dividend is calculated by multiplying the new term by the divisor. The new dividend is this difference.
We have to find the remainder if the divisor of a polynomial is a factor;
Here,
You know, from long division of regular numbers, that your residue (if there is one) has to be smaller than whatever you divided by. Since we're dividing by a linear factor (i.e., a factor whose degree on x is just an understandable "1"), the remainder in polynomial terms must be a constant value.
That is,
If a polynomial's divisor is a factor, the residual will always be a fixed number.
