Answer:
f(x) = - 3x + 4
Step-by-step explanation:
letting y = f(x) , rearrange making y the subject
Given
9x + 3y = 12 ( subtract 9x from both sides )
3y = - 9x + 12 ( divide all terms by 3 )
y = - 3x + 4, thus
f(x) = - 3x + 4 ← in functional notation

When can you use proportional reasoning to solve a problem? A: When two quantities add to 1 B: When one quantity is a constant multiple of the other C: When the two quantities multiplied equal a constant D: When one quantity is 1 more than the other
Proportional reasoning is a form of 'operational reasoning' based on
Piaget's theory.
Proportional reasoning can be used to solve a problem; B. When one
quantity is a constant multiple of the other.
Reasons:
Proportional reasoning is the reasoning based on the cognition that a
relationship exists between the multiples of the variables in the problem,
such that the magnitude of a variable can implied from the changes made
to the relationships connecting the variables.
An example of proportional reasoning is the distance travelled, d, after a
given time, t, at a constant velocity, v;
d = v·tTo judge the distance travelled, a constant, v, multiplies the time, t, such
that, at a longer time, it can be reasoned that the distance travelled is
much further.
Therefore;
Proportional reasoning can be used to solve a problem in which one quantity is a constant multiple of the other.Learn more here:

Options B and C are the correct conditions under which you can use proportional reasoning to solve a problem:
Proportional reasoning is a mathematical concept that involves understanding and solving problems that relate two or more quantities in a proportional manner. It helps us analyze and predict how changes in one quantity affect another based on their proportional relationship.
B: When one quantity is a constant multiple of the other:
In this case, if one quantity is a constant multiple of another, it means that they are directly proportional. For example, if the quantity of oranges you buy is always twice the quantity of apples you buy, then the quantities of oranges and apples are directly proportional. Proportional reasoning can be used to solve problems related to this relationship.
C: When the two quantities multiplied equal a constant:
If the product of two quantities remains constant, regardless of their individual values, they are inversely proportional. For instance, if the time taken to complete a task is inversely proportional to the number of people working on it, as the number of people increases, the time taken decreases. Proportional reasoning can be used to solve problems involving inverse proportionality.
In summary, proportional reasoning is used when two quantities are directly or inversely proportional to each other, i.e., when one quantity is a constant multiple of the other or when the product of the two quantities remains constant.

Given M is the midpoint ABA. The coordinate of A are (-4,2) and the cordinates of M are (1,1). Find the coordinate of B. Choose (-2,4) (-2,0) (6,4) (6,0)
Answer:
The coordinate of B is (6,0)
Step-by-step explanation:
Given;
coordinate of A = (-4,2) = (x₁, y₁)
coordinate of M = (1,1)
let coordinate of B = (x₂, y₂)
Mid-point is given by;
[tex]M = \frac{X_1 + X_2}{2} , \frac{Y_1 + Y_2}{2}\\\\M= (1,1)\\\\1,1 =\frac{X_1 + X_2}{2} , \frac{Y_1 + Y_2}{2}\\\\ \frac{X_1 + X_2}{2} = 1 ----equation (1)\\\\\frac{Y_1 + Y_2}{2} = 1 -----equation(2)\\\\Solving \ equation(1)\\\\\frac{-4+ X_2}{2} = 1\\\\-4+ X_2 = 2\\\\X_2 = 2+4\\\\X_2 = 6\\\\Solving \ equation(2)\\\\\frac{Y_1 + Y_2}{2} = 1\\\\\frac{2+ Y_2}{2} = 1\\\\2+Y_2 = 2\\\\Y_2 = 2-2\\\\Y_2 = 0\\\\B = (X_2, \ Y_2)\\\\B = (6, \ 0)[/tex]

Between each point of "5" there are 10 little squares in between and each number passes every 2 little squares. So we can use this to solve the questions.
Part A:
Count all the pupils who scored "more" than 7 using the assumption we made above.
12 scored more than 7
Part B:
Since we know that 14 scored more the seven, count all of the pupils who scored 7 and less.
15 scored a seven or less.
Add both numbers.
12 + 15 = 27 total pupils
Part C:
The assumption we had to make was to count each two little squares that represent one pupil to find the answer for Part B.

I been trying to figure the question out for the past 20 minutes and I can’t find the answer please help. (Question in picture)
Answer:
125°°
Step-by-step explanation:
∠DFC is a vertical angle with ∠BFE. As such, it is the sum of the right angle and the one marked 35°.
∠DFC = 90° +35°
∠DFC = 125°
_____
Alternate solution
∠CFA = 90° = ∠CFB +∠BFA
∠CFB = 90° -35° = 55°
∠BFC and ∠CFD are a linear pair, so total 180°
∠CFD = 180 -55° = 125° = ∠DFC
