Use the rise over run method.
2 is the same as 2/1. So, you rise 2 square up from the origin and then go over one, repeating the process. To do it in the negative zone, you just work backwards. Down two and left one.
You should have a diagonal line going from left to right that goes through the origin. Linear equations never end. They continue on forever, so your domain would be (-infinity, infinity) and your range would be (-infinity, infinity). Be sure to use the symbol for infinity instead of the word. The symbol, in case you do not know, looks like an 8 rotated 90 degrees.

So the proportion of the big triangle is 48:4 or 12:1. So if the small triangle’s height is 3 feet, then 3*12 is 36 feet.
Answer: 36 ft
Step-by-step explanation:
Similar triangles means there is a constant proportion between the left legs, the base legs, and the hypotenuses.
[tex]\frac{LeftLeg(large)}{LeftLeg(small)}= \frac{BaseLeg(large)}{BaseLeg(small)}[/tex]

Answer: (-4/3, 2)
The SSE for the data set is: 24
Step-by-step explanation:The data points are given by:
(3,6),(6,2),(9,10)
The data points are as follows:
when x=3 y=6
when x=6 y=2
and when x=9 y=10
Also, the line of best fit is as follows:
[tex]y=\dfrac{2}{3}x+2[/tex]
The SSE( sum of square for error ) is calculated as follows:
Firstly we find the y-values from the line of best fit corresponding to x-values as in the data points.Now we find the residual corresponding to each x.( i.e. difference between the actual y-value and y-value on the line of best fit)Square this difference quantities and add them up to get SSE of the data set.The y-values from the line of best fitwhen x=3
from the line of best fit we have: y=4
when x=6
then y=6
when x=9
then y=8
Hence, the residual value is:when x=3 6-4= -2
when x=6 2-6= -4
and when x=9 10-8=2
Hence, the square of these difference quantity is:
(-2)²=4
(-4)²=16
and (2)²=4
Hence, the sum of these square quantity is: 4+16+4=24
Hence, the SSE of data is: 24
Which of the functions below could have created this graph?
Answers
Answer:
The answer is C
Step-by-step explanation:
The correct option is A. (F(x)=-x^{7}+4x^{3}-2x^{2}). This function matches all the key properties observed in the graph.
Sure, I've analyzed the image you sent and I can help you determine the correct option.
Based on the graph, we can see that it has the following properties:
It has three turning points, one minimum point and two maximum points.
The end behavior as x approaches positive or negative infinity is that the function increases without bound.
It intersects the x-axis three times.
Let's analyze the answer choices based on these observations:
Option A: (F(x)=-x^{7}+4x^{3}-2x^{2})This function has an odd leading term, which aligns with the increasing end behavior.
It has three factors, matching the number of x-intercepts.
By graphing this function, we can see that it matches the shape of the given graph with a minimum point followed by two maximum points.
Option B: (F(x)=x^{8}+4x^{4}+20x^{2})This function has an even leading term, which does not align with the increasing end behavior.
Even though it has four factors, it intersects the x-axis only twice.
Option C: (F(x)=x^{9}+12x^{8}+x^{7})This function has an odd leading term, which aligns with the increasing end behavior.
However, it only has two factors, not matching the three x-intercepts of the graph.
Option D: (F(x)=-x^{6}+x^{3}-x^{2})This function has an even leading term, which does not align with the increasing end behavior.
It also only has two factors, not matching the three x-intercepts of the graph.

You go to a school dance. There is an entrance fee, and there are slices of pizza for sale. After having 1 slice of pizza, you have spent a total of $6. After having 2 more slices of pizza, you have spent a total of $10. Write an equation that represents the total cost y after buying x slices of pizza at the dance.
Answers
Each slice was 2$ entrance fee was 4$
The equation representing the total cost after buying x slices of pizza
is [tex]\( C(x) = E + x \times P \)[/tex].
Let's denote the entrance fee as E (in dollars) and the cost of each slice of pizza as P (also in dollars). Given the problem, we can write the following equations based on the given information:
After having 1 slice of pizza, the total cost is $6:
[tex]\(E + 1 \times P = 6\)[/tex]
After having 2 more slices of pizza (total 3 slices), the total cost is $10:
[tex]\(E + 3 \times P = 10\)[/tex]
To find the equation that represents the total cost (y) after buying x slices of pizza (let's call it C(x), we need to generalize the pattern observed in the given equations.
Notice that the entrance fee remains constant regardless of the number of slices of pizza bought. So, we can write the equation as:
[tex]\[ E + x \times P = C(x) \][/tex]
Substituting the values given in the problem:
[tex]\[ C(x) = E + x \times P \][/tex]
So, the equation representing the total cost after buying x slices of pizza
is [tex]\( C(x) = E + x \times P \)[/tex]. This equation gives the total cost (y) as a function of the number of slices of pizza bought (x).
if the bases of an isosceles trapezoid have lengths of 13 and 26 what is the length of the median
Answers
Answer: the answer is C . 19.5 units - APEX :D
Answer:
Answer is 19.5 units
Step-by-step explanation:
Given that there is a trapezoid.
Its bases are 13 and 26 respectively.
Non parallel sides are congruent
To find the median that is the length of line connecting the midpoints of the non parallel sides
If we draw any one diagonal we see that median is the line connecting the mid point of two triangles with the parallel sides as bases
Hence length of median= 1/2 (base 1+base 2)
(By triangle mid point theorem)
= 1/2 (13+26)
=19.5 units

Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.

Answers
Step-by-step explanation:
We are given the co-ordinates,
x : -2, -1, 0, 1, 2
y : 8, 5, 2, -1, -4
According to the graph, we see that this function represents a straight line.
The general form of the straight line is y = mx + c, where m is the slope and c is the y-intercept.
So, taking any two points we will find the equation of the straight line.
Consider, (0,2) and (1, -1). Now, slope is given by,
m = [tex]\frac{-1-2}{1-0}[/tex]
i.e. m = -3
Now, we will find the y-intercept of this equation using (0,2) and m = -3,
i.e. y = -3x + c
i.e. 2 = c
Hence, the equation of the straight line is y = -3x + 2.

Integration of (3X(X^2+3)^4) dx
[tex] [/tex]
Answers
Answer:
Step-by-step explanation:
[tex]\int 3x(x^2+3)^4 \ dx[/tex].
It is apparently obvious we could expand the bracket and integrate term-by-term. This method would work but is very time consuming (and you could easily make a mistake) so we use a different method: integration by substitution.
Integration by substitution involves swapping the variable [tex]x[/tex] for another variable which depends on x: [tex]u(x)[/tex]. (We are going to choose [tex]u[/tex] for this question).
The very first step is to choose a suitable substitution. That is, an equation [tex]u=f(x)[/tex] which is going to make the integration easier. There is a trick for spotting this however: if an integral contains both a term and it's derivative then use the substitution [tex]u=\text{The Term}[/tex].
Your integral contains the term [tex]x^2 + 3[/tex]. The derivative is [tex]2x[/tex] and (ignoring the constants) we see [tex]x[/tex] is also in the integral and so the substitution [tex]u=x^2+3[/tex] will unravel this integral!
Step 2: We must now swap the variable of integration from x to u. That means interchanging all the x's in the integrand (the term being integrated) for u's and also swapping (dx" to "du").
[tex]u=x^2+3 \Rightarrow \frac{du}{dx}=2x \Rightarrow dx = \frac{1}{2x} du[/tex]
Then,
[tex]\int 3x(x^2+3)^4 \ dx = \int 3x \cdot u^4 \cdot \frac{1}{2x} du = \int \frac{3}{2}u^4\ du[/tex].
The substitution has made this integral is easy to solve!
[tex]\int \frac{3}{2}u^4\ du= \frac{3}{10}u^5 + C[/tex]
Finally we can substitute back to get the answer in terms of x:
[tex]\int 3x(x^2+3)^4 \ dx = \frac{3}{10}(x^2+3)^5+C[/tex]
