Answer:factor of x³ + 343
Step-by-step explanation: Option D is correct. A factor of an expression is usually referred to as a number or an algebraic expression that divides the known expression. The above algebraic expression needs to be expanded to determine its factor; Mathematically; x³ + 343 = (x + 7) (x² - 7x + 49) Therefore, we can conclude that the factors are (x + 7) (x² - 7x + 49)
Three friends go grocery shopping together, and each buys the same kind of oranges. LaMar buys 2 pounds (lb) and pays $7.00. Enrico buys 5 pounds and pays $17.50. Anna buys 3 pounds and pays $10.50. Identify the graph and unit price that represent the orange costs.
The unit price of the oranges bought by the three friends is $3.50 per pound.
Lamar bought 2 pounds for $7 , unit price = 7 / 2 = $ 3.5 per pound
Enrico bought 5 pounds for $17.50 , unit price = 17.50 / 5 = $ 3.5 per pound
Anna bought 3 pounds for $10.50 , unit price = 10.5/ 2 = $3.5 per pound
Hence we can see that the unit price rate for the oranges is $3.50 .
The average price of a product is calculated by dividing the total sales income by the number of units sold. Managers must supply "similar" units when a single product is given in many variations, such as different bottle sizes.
By weighting different unit selling prices higher by unit sales mix (%) for each single variant, the determination of average pricing is made practicable. We obtain pricing per statistical unit when we employ a standard rather than a genuine range of sizes and product types.

The coordinates of the vertices of ΔA'B'C' after the transformation are (a) A'(-2, 8), B'(-17, 11), C'(-9, 0)
How to determine the vertices of ΔA'B'C'?The coordinates of the triangle are given as
ΔABC are A(7, 3), B(−8, 6), C(0, −5).
The transformation is given as
∆ABC is translated along the vector <−9, 5>
Mathematically, this can be represented as
(x, y) ⇒ (x - 9, y + 5)
When this is applied on ABC, we have:
ΔA'B'C' = A'(7 - 9, 3 + 5), B'(−8 - 9, 6 + 5), C'(0 - 9, −5 + 5)
Evaluate the computations
ΔA'B'C' = A'(-2, 8), B'(-17, 11), C'(-9, 0)

Answer: Location of T' on the coordinate axis will be (16,7).
T (6,4) → T' (16,7).
Step-by-step explanation:
coordinate vertices of points in rectangle JKLM are:
J (-8,-8)
K (-4,-8)
L (-4,-5)
M (-8,-5)
and coordinate vertices of points in rectangle J'K'L'M' are:
J' (2,-5)
K' (6,-5)
L' (6,-2)
M' (2,-2)
coordinate vertices of points in Quadrilateral STUV are:
S (1,4)
T (6,4)
U (4,6)
V (2,6)
transformation in coordinate vertices from rectangle JKLM to rectangle J'K'L'M' is:
J (-8,-8) → J' (2,-5)
⇒ along x axis -8 → 2 which means that rectangle is shifting towards right by 10 units.
and along y axis -8 → -5 which means that the rectangle is shifting upwards by 3 units.
similarly for
K (-4,-8) → K' (6,-5)
⇒ along x axis -4 → 6 which means that rectangle is shifting towards right by 10 units.
and along y axis -8 → -5 which means that the rectangle is shifting upwards by 3 units.
L (-4,-5) → L' (6,-2)
⇒ along x axis -4 → 6 which means that rectangle is shifting towards right by 10 units.
and along y axis -5 → -2 which means that the rectangle is shifting upwards by 3 units.
M (-8,-5) → M' (2,-2)
⇒ along x axis -8 → 2 which means that rectangle is shifting towards right by 10 units.
and along y axis -5 → -2 which means that the rectangle is shifting upwards by 3 units.
So, the location of T' of the Quadrilateral S'T'U'V' on the coordinate plane will be:
along x axis the Quadrilateral will shift towards right by 10 units
So, 6 → 6+10=16
and along y axis the Quadrilateral will shift upwards by 3 units
So, 4 → 4+3=7
⇒ T (6,4) → T' (16,7).

what are the domain and range or this exponentiAl function y=1/6.8×
We want to identify the domain and range of the following function
[tex]\frac{1}{6}\cdot8^x[/tex]Recall that the domain of a function is the set of values for the variable x, for which the function is defined. Note that we can see this function as the product of two different functions
[tex]\frac{1}{6}[/tex]and
[tex]8^x[/tex]Note that the first part (1/6) does not depend on x, so this means that it is always defined. Also, note that 8^x is always defined for any value of x. That is, if you replace x by any number, you will get another number.
So, this means that the the original function is defined for every value of x. So the domain of this function is the set of all real numbers.
If we define the equation
[tex]y=\frac{1}{6}\cdot8^x[/tex]the range is the set of all possible values that y can take. Taking a look at the functions we already identified (1/6, and 8^x) we can see that 1/6 is always a positive number, and we can also see that for every value of x, the number
8^x is always positive.
That means that the product
[tex]\frac{1}{6}\cdot8^x[/tex]is always a positive number. So, this means that the range of the function is all positive real numbers. That is the set of y such that y>0
