function rule to find f(11).
the next question is more point go check it out after you answer this question!!!!!
The solution for f(11) in the function when the function f(x) = 12|x + 8| is 228
How to determine the solution for f(x) in the function?From the question, we have the following equation that can be used in our computation:
f(x) = 12|x + 8|
The above equation is an absolute value equation
An absolute value equation has the following representation
f(x) = a|x - h| + k
So, we have the following representation
f(x) = 12|x + 8|
Also from the question, we have
f(11)
This means that the value of x is 11, and we calculate f(x) when x = 11
Substitute the known values in the above equation, so, we have the following representation
f(11) = 12|x + 8|
So, we have the following equation
f(11) = 12|11 + 8|
There are constants to add or subtract to both sides of the equation
Also, there are factors to multiply or divide from both sides of the equation
So, we have the following representation
f(11) = 12|19|
Solving further, we have
f(11) = 12 * 19
Evaluate the products
f(11) = 228
Hence, the solution is 228

What is the equation for the line in slope-intercept form?
Answer:
y = -2x - 4
Step-by-step explanation:
y = mx +b is the slope intercept form of a line. The m is the slope and the b is the y intercept.
The y intercept is where the line crosses the y axis. It crosses at the point (0,-4). The -4 is where the line crosses the y axis. It is the b.
The slope is the change in y over the change in x. To go from point (0,-4) to the point (-2,0) You go up 4 units and the left 2 units. Up is positive and left is negative. 4/-2 which simplifies to -2. This is your m.

The abscissa or x-coordinate of any point on Y-axis is zero.
Which line is the x-coordinate?
Two parallel lines, known as axes (pronounced AX-eez), that are perpendicular to each other make up a coordinate grid. Typically, the term "x-axis" refers to the horizontal axis. The y-axis is the common name for the vertical axis.
The ordinate and abscissa are other names for the x-axis and y-axis, respectively. These two axes can be used to find or represent any point on the coordinate plane as an ordered pair of the form (x,y).
The equation of a line is typically written as y=mx+b where m is the slope and b is the y-intercept.
In order to represent the equation in y-intercept (y=mx+b) form, the slope and y-intercept must be included. The slope is the ratio of the y-to-x change. Draw a sloping triangle connecting the two spots you find on the line.

Therefore the solution of this question is Sam can draw 2 lines of reflection.
What is line of reflection?If a figure is reflected in a line or a point, the image and preimage are consistent. A reflection converts each point in a figure into an image along a predetermined line. Line of Reflection refers to the fixed line.
To determine the quantity of lines that will reflect a rectangle back onto itself.
Due to the fact that the line of reflection is the perpendicular bisector of the segment connecting a point with its image. The perpendicular bisector of a side must be the line of reflection if one side of the rectangle is to map to itself.
A rectangle has two distinct perpendicular bisectors of its sides, leading to two lines of reflection that map a rectangle to itself.

Consider the system of equations
5x+3y=30
−5x−2y=−25
Part A: Solve the system. Show your work.
_______
Part B: Use the solution to your equation to find the value of x – y. Show your work.
x−y = _____
By solving the two equations, the values of x , y and x-y are found to be 1, 25/3 and -22/3 respectively.
Given two equations are;
5x+3y=30..........(1)
−5x−2y=−25.........(2)
Now , from (2)
−5x−2y=−25
⇒ 5x +2y = 25 (multiply both sides with '-' sign)
⇒ y = [tex]\frac{(25 -5x)}{2}[/tex]
Solving the system;
substitute the above vale of y in eq (1)
5x + 3y = 30
⇒ 5x + 3 ( [tex]\frac{(25 -5x)}{2}[/tex]) = 30
⇒ 5x + ([tex]\frac{(75 - 15x)}{2}[/tex]) = 30
⇒ [tex]\frac{10x+75-15x}{2}[/tex] = 30
⇒ -5x + 75 = 60
⇒ -5x = -5
⇒ x = 1
∴ x = 1
Now substitute the value of x in (1)
5x + 3y = 30
⇒ 5 × 1 + 3y = 30
⇒ 3y = 25
⇒ y = 25/3
∴ y = 25/3
Now using the value of x and y , we can find the value of x - y
x - y = 1 -25/3 = (3 - 25)/ 3 = -22/3
∴ x - y = -22/3

b) 270
Step-by-step explanation:
a)
(√5)² = 5
(√3)² = 3
This is due to the square root and to the power of 2 cancelling each other out if that makes sense. It's the same with (√3)²
So all you're actually doing is 5 × 3 which is 15
b)
It's basically the same except (³√9)³ is cube(d) root and to the power of 3
(³√9)³ = 9
(√30)² = 30
