(x-4)(x-3) so what you do is
x -4
x x^2 -4x
-3 -3x 12
x^2-7x+12
your answer would be -7x
Answer:
The correct option to tell whether a relationship is proportional or not is;

Step-by-step explanation:
A proportional relationship is a relationship between two variables, 'x', and 'y' such that they have equivalent ratio, such that all values of variable 'y' are given by the product of the values of the variable 'x' and a constant, 'k'
Therefore, y = k · x, from which we have;

Therefore we can use
to tell whether a relationship is proportional or not proportional.
Answer:
B
Step-by-step explanation:
Because the initial value is $26.40, the line must pass through this when x is 0. Thus, the answer is either the first or the second equation.
Next, we calculate the difference between the year 2019 and 1998 and substitute it into the value of x.
2019 - 1998 = 21.
Substituting this into the equation:
y = 1.006(21) + 26.40
y = $47.52
Thus, the first option is correct.
Answer: ( 2 , - 15 )
Step-by-step explanation:
Given :
endpoint = ( 0 , -1 )
midpoint = ( 1 , - 8 )
Let the other end point be ( x , y )
The equation for finding the mid point of a line segment is given by :
mid point = (
, 
This means
(1 , -8 ) = (
,
)
Equating the x - component , we have
1 = 
1 = x/2
Therefore
x = 2
Also equating the y - component
- 8 = 
-16 = -1 + y
-15 = y
Therefore :
y = -15
Therefore , the other endpoint is :
( 2 , - 15 )
