Answer:
x + 3 + x
Step-by-step explanation:
3x :
This is a product of two terms, where x is any variable.
3 + x :
This is sum of two terms,where x is any variable.
x^3 :
This expresses x to the power of three. It can also be written as (x times x times x ). Thus it is the product of three terms, where x is any variable.
x + 3 + x :
This is the sum of three terms, where x is any variable.
Thus answer is x + 3 + x

The graphs below have the same shape. What is the equation of the blue
Answer: The correct option is B.
Explanation:
From the given figure it is noticed that the parent function is,
[tex]f(x)=x^2[/tex]
The graph of f(x) shifts 5 units right.
The transformation is defined as,
[tex]g(x)=f(x+a)+b[/tex]
Where, a shows the horizontal shifts and b shows the vertical shift.
If a<0 then the graph of f(x) shifts right side by a units and if a>0 then the graph of f(x) shifts left side by a units.
If b<0 then the graph of f(x) shifts downward by b units and if b>0 then the graph of f(x) shifts upward by b units.
Since the graph of parent function is shifts only right side by 5 units, therefore
[tex]g(x)=f(x-5)+0[/tex]
Since [tex]f(x)=x^2[/tex]
[tex]g(x)=(x+5)^2[/tex]
Thus, the correct option is B.
The function in option A represents the left shift of f(x) by 5 units. The option C represents the downward shift of f(x) by 5 units. The option D represents the upward shift of f(x) by 5 units.
Consider the two triangles shown.

Let f(x)=25x2−2 .
The function g(x) is a vertical stretch of f(x) by a factor of 2.
What is the equation of g(x)?
Enter your answer in the box.
g(x) =
We are given function f(x) = 25x^2 -2.
g(x) is a vertical stretch of f(x) by a factor of 2.
We know, the transformation rule
y= k f(x), vertical stretch by a factor k. For k>0.
Because function f(x) is being vertical stretched by a factor of 2. So, we need to multiply f(x) function by 2.
Therefore, g(x) = 2 f(x) = 2*(25x^2-2).
Therefore, g(x) = 2*(25x^2-2) or g(x) = 50x^2-4.
Answer:
The Given function is
f(x)= 25 x² -2
Now, a function g(x) is obtained when the function f(x) is stretched by a factor of 2.
Consider point (x,y) on f(x).When function is stretched vertically by a factor of 2 ,it means, the coordinate changes from (x,y) to (x,2 y).
Since we have to stretch the function as whole, we will multiply original function by 2.
So, g(x)= 2× [25 x² - 2] =50 x² -4
g(x)=50 x²- 4

From the second month onward, the number of hours of hip hop music she downloads each month is nine percent greater than the number of hours of hip hop music she had downloaded the previous month. Which function best shows the total number of hours of hip hop music Wendy has in her collection f(x) after x months? f(x) = (1.09)x + 3 f(x) = 3(1.09)x f(x) = (1.09)x + 2 f(x) = (1.09)x - 2
In the figure, TU is tangent to the circle at point U. Use the figure to answer the questions.
(a) Describe the relationship among the lengths of the segments formed by the secant, RT, and the tangent segment, TU. You may use words and/or an equation.
(b) Suppose RT = 9 in. and ST = 4 in. Is it possible to find the length of TU? If so, show how to find the length. If not, explain why not.
Both the parts of this question require the use of the "Intersecting Secant-Tangent Theorem".
Part A
The definition of the Intersecting Secant-Tangent Theorem is:
"If a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment."
This, when applied to our case becomes, "The length of the secant RT, times its external segment, ST, equals the square of the tangent segment TU".
Mathematically, it can be written as:
[tex] RT\times ST=(TU)^2 [/tex]
Part B
It is given that RT = 9 in. and ST = 4 in. Thus, it is definitely possible to find the value of the length TU and it can be found using the Intersecting Secant-Tangent Theorem as:
[tex] RT\times ST=(TU)^2 [/tex]
Thus, [tex] (TU)^2=9\times 4=36 [/tex]
[tex] \therefore TU=\sqrt{36}=6 [/tex]
Thus the length of TU=6 inches

In a triangle we apply angle sum property of triangle, which is given by:
Sum of angles of triangle =180 degrees.
We are given three angles,
A =(4x-13)
B =15
C =(x+18)
Adding the three angles and equating it to 180,
[tex] (4x-13) +15 + (x+18) =180 [/tex]
combining like terms
[tex] 5x+20 =180 [/tex]
[tex] 5x=180-20 [/tex]
[tex] 5x =160 [/tex]
x=32
angle A = 4x-13 = 4(32)-13 = 115 degrees.
angle C = x+18 = 32 +18 = 50 degrees.
Answer : angle A is 115 degrees and Angle C is 50 degrees.

Answer:
C
Step-by-step explanation:
The very first term would result in 2 having an exponent in 0 making the equation -3 * 1 which is just -3 and C is the only option.
To further prove this -3 * 2^3 is -24. n is the term that you are looking for. So finding the fourth term would mean you would take 4-1 which is 3 thus making the exponent 3.

Which equation represents a line which is parallel to the line x-8y=48 x−8y=48?
The required line is y = x/8 - 6 which is parallel to the given line x − 8y = 48.
What is the Linear equation?A linear equation is defined as an equation in which the highest power of the variable is always one.
The slope-intercept form is y = mx+c, where the slope is m and the y-intercept is c
The equation is given in the question below as
x − 8y = 48
We have to convert the equation to slope-intercept form
x − 8y = 48
− 8y = - x + 48
Divided by -8 into both sides of the above equation,
− 8y / (− 8) = - x / (− 8) + 48 / (− 8)
y = x/8 - 6
Since the slope is the same, therefore the lines are parallel.
Therefore, the required line is y = x/8 - 6 which is parallel to the given line x − 8y = 48.
Hence, the correct answer would be an option (A).
