Using linear function concepts, we have that:
For a graph in a 1:1 scale, we can look at two consecutive values, y when x = a and y* when x = a + 1, and subtract y* by y. For a graph in another scale, we also do the same thing, but since the scale is not 1:1, we have to divide the subtraction of y* by y by the scale.What is a linear function?A linear function is modeled by:
y = mx + b
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.Given two points in a graph, the slope is given by change in y divided by change in x, hence:
For a graph in a 1:1 scale, we can look at two consecutive values, y when x = a and y* when x = a + 1, and subtract y* by y. For a graph in another scale, we also do the same thing, but since the scale is not 1:1, we have to divide the subtraction of y* by y by the scale.More can be learned about linear function concepts at https://brainly.com/question/24808124

3x - 7x-16 = - 4x + 5 - 16
Answer:
no solution
Step-by-step explanation:
3x - 7x - 16 = -4x + 5 - 16
combine like terms
-4x - 16 = -4x - 11
move the terms with variables to one side and constants to the other
add 4x to move it
-4x + 4x = 0
-16 = - 11
this is not possible so there is no solution
Answer:
0=5
Step-by-step explanation:
3x - 7x - 4x + 5 - 16
-4x - 16 = -4x + 5 -16
-4x - 16 = -4x -11
-4x -16 + 16 = -4x - 11 + 16
-4x = -4x + 5
-4x + -4x = -4x + 5 + 4x
combine like terms
repeat that

can someone derive f(x) = x using first principles method. Like I know the answer is 1 and can do it by power rule but i cannot get that answer for the life of me using first principles method.
fyi first principles function is in the pic
The derivation by definition of f(x) = x, that is, f'(x) = 1, is found in this problem.
How to find the derivative of function f(x) by the definition?The derivative is given by:
[tex]f^{\prime}(x) = \lim_{h \rightarrow 0} \frac{f(x + h) - f(x)}{h}[/tex]
For this problem, we have that:
f(x) = x.f(x + h) = x + h.Hence:
[tex]f^{\prime}(x) = \lim_{h \rightarrow 0} \frac{x + h - x}{h}[/tex]
[tex]f^{\prime}(x) = \lim_{h \rightarrow 0} \frac{h}{h}[/tex]
[tex]f^{\prime}(x) = \lim_{h \rightarrow 0} 1[/tex]
The limit of a constant is the constant, hence f'(x) = 1.

For the given system of inequalities, x represents the number of brownies and y the number of cookies.
And the graph can be seen in the image below.
What each variable represents?Here we have the system of inequalities:
4x + 6y ≥ 200
x + y < 75.
We know that they want to make less than 75 items, that is what the second inequality:
x + y < 75.
Represents.
We also know that each brownie costs $4, and each cookie costs $6, then the expression:
x*4 + y*6
Represents the revenue for selling x brownies and y cookies, and because they want to earn at least $200, the inequality becomes:
x*4 + y*6 ≥ 200
So we conclude that x represents the number of brownies and y the number of cookies.
Now the system is:
4x + 6y ≥ 200
x + y < 75.
To graph it, you just need to graph both the lines and shade the indicated region, we can write the inequalities sa:
y ≥ (200 - 4x)/6
y < 75 + x
Just graph these two lines, for the first one you need to use a solid line and shade the region above the line, for the second, a dashed line and you need to shade the region below the line. The graph can be seen below.
The solutions to the systems are in the region where both shaded parts intersect.
There we can see that the point x = 20 and y = 20 (among a lot of other ones) is a solution to the system.

2/5a - 3/4b =c solve for a
The equation (2/5)*a - (3/4)*b = c solved for the variable a is:
a = (5/2)*(c + (3/4)*b)
How to solve the equation for a?Here we have the equation:
(2/5)*a - (3/4)*b = c
Where a, b, and c are variables.
Here we want to solve this equation for the variable a, this means that we need to isolate that variable in one side of the equation, so let's do that.
First, we need to remove the other term, then we can add its opposite in both sides of the equation so we get:
(2/5)*a - (3/4)*b + (3/4)*b = c + (3/4)*b
(2/5)*a = c + (3/4)*b
Now we need to remove the factor that multiplies the variable, we can do that by multiplying both sides of the equation by its inverse, whic is 5/2, if we do that we will get:
(5/2)*(2/5)*a = (5/2)*(c + (3/4)*b)
a = (5/2)*(c + (3/4)*b)
This is the equation solved for the variable a.

Point F is on line segment EG. Given EG = 12 and FG = 8, determine the length
EF.
Given that Point F is on line segment EG, the Length of segment EF is 4.
What is the numerical length of segment EF?A line segment is simply part of the line that connects 2 points.
Given the data in the question;
Point F is on line segment EGSegment EG = 12Segment FG = 8Length of segment EFSince Point F is on line segment EG, length of segment EG equals the sum of length of segment EF and length of segment FG.
Length of segment EG = Length of segment EF + Length of segment FG
Hence;
12 = Length of segment EF + 8
Subtract 8 from both sides and simplify
12 - 8 = Length of segment EF + 8 - 8
12 - 8 = Length of segment EF
4 = Length of segment EF
Length of segment EF = 4
Given that Point F is on line segment EG, the Length of segment EF is 4.

Given P||Q and T is a transversal, which of the
following justifies <1 = 25?
A Corresponding Angles Postulate
B. Alternate Interior Angles Theorem
c. Consecutive Interior Angles Theorem
D. Alternate Exterior Angles Theorem
If P||Q and T is a transversal, then ∠1=∠5 can be justified through Corresponding angle postulate. Thus, correct option is option A.
The Corresponding angle postulate states that if two lines are drawn on plane which are parallel to each other and dissected by a line passing through them at any angle then the corresponding angle of both the parallel lines will be equal to each other and hence would be congruent.
Here, P||Q and P and Q are dissected by the line T at some angle therefore to prove that ∠1=∠5 we go by the following steps:
∠4=∠5 as they are alternate interior angles.
and ∠1=∠4 as they are vertically opposite angles.
Thus, ∠1=∠5 and they are corresponding angles.

We are given a linear function:
f(x) = 2 x + 3
We are also given the domain of the function as:
Domain = (-4, 5)
We need to find the range of the function and draw its graph.
For x = -4, the value of function will be:
f( -4) = 2 (-4) + 3
f( -4) = - 8 + 3
f( -4) = - 5
For x = 5, the value of function will be:
f( 5) = 2 (5) + 3
f( 5) = 10 + 3
f( 5) = 13
So, the range will become:
( -5, 13)
The graph of the function with points:

Painted Cubes
Imagine that we paint a 4 x 4 x 4 cube blue on every side.
How many of the small cubes have 3 blue faces?
How many have 2 blue faces?
How many have 1 blue face?
How many faces would be painted in a cube of any size?
How many have not been painted at all?
If we paint a 4 x 4 x 4 cube blue on every side then we will get 8 small cubes having 3 blue faces, 16 cubes having 2 blue faces, 24 cubes with 1 blue face, 6 faces would be painted in a cube of any size and 8 cubes have not been painted at all.
Elaborate the answer that is obtained above.Corner cubes are the only ones with 3 faces, whereas a cube has 8 corners. There are therefore 8 cubes with 3 blue faces.
Each of the 16 cubes has 2 blue faces. These are the cubes found between the sides' corners.
The 4 center cubes have only 1 side painted. Because each side has six sides and four center cubes, 6 x 4 = 24. As a result, 24 cubes have 1 blue face.
Because a cube has 6 faces, every size cube will have at least 6 colored faces.
On the inside of the larger cube, there are exactly 8 cubes. As a result, 8 cubes have been left unpainted.
