Write a linear function f with the values f (3) = -1 and f (6) = 1.
A function is f (x) =

Step-by-step explanation:
The linear equation for the function is f ( x ) = y = ( 2/3 ) x - 3
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation be f ( x ) = y
Now , the value of the function f ( 3 ) is given in the equation as
f ( 3 ) = -1
And the value of the function f ( 6 ) is given in the equation as
f ( 6 ) = 1
So ,
when x = 3 , y = -1
and when x = 6 , y = 1
Now , we have two points A ( x₁ , y₁ ) and B ( x₂ , y₂ )
A ( x₁ , y₁ ) = A ( 3 , -1 )
B ( x₂ , y₂ ) = B ( 6 , 1 )
Now ,
To find the slope of the equation , we use
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Substituting the values , we get
Slope m = ( 1 - ( -1 ) ) / ( 6 - 3 )
= 2 / 3
Now , the equation of line will be y - y₁ = m ( x - x₁ ) ,
So , substituting the value of m , we get
y - ( -1 ) = ( 2/3 ) ( x - 3 )
y + 1 = ( 2/3 )x - 2
Subtracting 1 on both sides , we get
y = ( 2/3 )x - 3
Therefore , the equation of line will be y = ( 2/3 )x - 3
Hence , The linear equation for the function is f ( x ) = y = ( 2/3 ) x - 3

consider the graph f(x)=3 to the power of x. describe how to graph the transformation f(x-3)+2
Answer:
shift the graph horizontally to the right for 3 units and then shift vertically up 2 units
Step-by-step explanation:
f(x) = x³ vs f(x-3)+2
f(x-3) will shift the graph horizontally to the right for 3 units
+2: will shift vertically up 2 units

I NEED HELP ASAP!!!!! Solve the equation and enter the value of x below.
Answer:
x = -5
Step-by-step explanation:
-3x - 4 = 11
add 4 to both sides
-3x = 15
divide by -3
x= -5
plug it in to check:
-3 (-5) - 4 = 11
-3 times -5 is 15
15 - 4 = 11
Solve for X. 12y-4x=10
Answer:
x=-5/2+3y
Step-by-step explanation:
If this answer helped you then please consider making this brainliest and thank this response :)
Answer:
x = -2.5 + 3y
Step-by-step explanation:
Simplifying
12y + -4x = 10
Reorder the terms:
-4x + 12y = 10
Solving
-4x + 12y = 10
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-12y' to each side of the equation.
-4x + 12y + -12y = 10 + -12y
Combine like terms: 12y + -12y = 0
-4x + 0 = 10 + -12y
-4x = 10 + -12y
Divide each side by '-4'.
x = -2.5 + 3y
Simplifying
x = -2.5 + 3y
Determine if the side lengths given form a triangle. Justify your response. 6.4 mm, 12.9 mm, 14.2 mm
Answer:
Step-by-step explanation: Yes I think since if you add 12.4 and 6.4 your answer is more then 14.2 so yes it is possible
Answer:
Yes, it does form a triangle
Step-by-step explanation:
According to the first triangle inequality theorem, the lengths of any two sides of a triangle must add up to more than the length of the third side. This means that the given side lengths DO form a triangle. 6.4+12.9=19.3 which is more than 14.2.

f(x) = x + 4
f(x) = 4x
f(x) = x – 4
f(x) = 4 – x
Answer:
f(x) = 4 - x
Step-by-step explanation:
'f(x) = blah-blah' is the same as saying 'y = blah-blah', except it is also telling you that the x-y relationship is a function.
I notice that for each case, x + y = 4, so y = 4 - x
Or in 'function' terminology, f(x) = 4 - x
