what are the like terms in the expression 8+x^2-4x^3+5x+2x^2?
Answer:
B. x^2x2 and 2x^22x2
Step-by-step explanation:
The expression given is:
8+ x^2 - 4x^3 + 5x+ 2x^28+x2−4x3+5x+2x2
Like terms are terms in which their variables and the power of the variables (exponents) are the same.
While it is not necessary that the coefficient of the variables are the same, the power of the variables must be the same.
In that case, the like terms in the expression given are x^2x2 and 2x^22x2 .
Note: The question says 8+ x^2 - 4x^3 + 5x+ 2x^28+x2−4x3+5x+2x2 but the option has -4x^2−4x2 .
In case its actually -4x^2−4x2 instead of -4x^3−4x3 , then,
-4x^2−4x2 is also a like term and the answer will be D.
HOPE IT HELPS..Katherine's bakery expects to sell 20 Bundt cakes every 5 days. Based on this information, how many days does the bakery expect that it will take to sell 44 Bundt cakes?
Answer:
the number of days taken is 11
Step-by-step explanation:
The computation of the number of days expected to sell 44 bundt cakes as follows:
Given that
It takes every 5 days to sell 20 bundt cakes
So for 44 bundt cakes it would take
= 44 × 5 days ÷ 20
= 11 days
hence, the number of days taken is 11

What is true about the sum of the two polynomials?
6s2t – 2st2

What is the additive inverse of the polynomial –9xy2 + 6x2y – 5x3?
Answer:
f'(x) = -f(x) = 9xy² - 6x²y + 5x³
Step-by-step explanation:
f(x) = –9xy² + 6x²y – 5x³
additive inverse: f'(x) = -f(x) = 9xy² - 6x²y + 5x³
f(x) + f'(x) = f(x) -f(x) = (–9xy² + 6x²y – 5x³) + (9xy² - 6x²y + 5x³) = 0

During a certain period of time, about 70 northern sea otters had an annual growth of 18%. Use an exponential function to find the number of sea otters after 4 years.
Answer:
135.71 sea otters
Step-by-step explanation:
y = 70(1.18)^4
y = 70 x 1.9387
y = 135.71
The number of sea otters after 4 years with an exponential growth of 18% will be 135.71.
What is an exponential function?A connection of the form y = ax, where x is an independent variable that spans the entire real number line and is written as the exponent of a positive number, is known as an exponential function in mathematics.
The exponential growth function is given as,
y = C x^n
y = 70(1.18)⁴
y = 70 × 1.9387
y = 135.71
Hence "After 4 years, there will be 135.71 sea otters, representing an exponential growth of 18%".

Two groups are hiking at about the same speed . Mario’s group hikes for 2.5 hours Seemas group hikes for 4.7 hours and covers 8.8 more miles . How fast are the kickers going ? Solve the equation below to find out . 4.7x=2.5x+8.8
Answer: 18.8 miles
Step-by-step explanation:
Ww are given the equation 4.7x=2.5x+8.8 to solve the question. This will be:
4.7x = 2.5x + 8.8
Collect like terms.
4.7x - 2.5x = 8.8
2.2x.= 8.8
x = 8.8/2.2
x = 4
To know how fast the kickers are going will be
4.7x = 4.7 × 4 = 18.8 miles

Answer:
y = -0.5x + 3
Step-by-step explanation:
The equation of a linear model is generally represented as;
y = mx + b
where m
is slope and b is the y-intercept
We can get slope by using the slope equation
m =
(y2-y1)/(x2-x1)
(x1,y1) = (-4,5)
(x2,y2) = (4,1)
m = (1-5)/(4 + 4) = -4/8 = -0.5
The equation is thus;
y = -0.5x + b
to get b, we substitute any of the two points coordinates
1 = -0.5(4) + c
1 = -2 + c
c = 2 + 1
c = 3
The space probe Voyager I travels 3.255 x 108 miles in a year.
At this rate, how far does the Voyager I travel during a period of 40 years?
The Voyager I travel 130.2 x [tex]10^8[/tex] miles during a period of 40 years.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
The space probe Voyager I travels 3.255 x [tex]10^8[/tex] miles in a year.
So, in 40 years Voyager I travel
= 3.255 x [tex]10^8[/tex] x 40
= 130.2 x [tex]10^8[/tex] miles.
Thus, the Voyager I travel 130.2 x [tex]10^8[/tex] miles.

Answer:
To determine if the point is a solution, substitute the x value into the right side of the inequality and compare the result with the y value of the point.

Find the slope given the points (2, −7) and (−1, 6).
Answer:
The slope would be 13/-3 or -4.3... repeating
Step-by-step explanation:
The slope of the line passing through the points (2, −7) and (−1, 6) is (13 / 3 ).
What is the slope of the line?Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line.
The slope of the line is calculated by the formula below,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given points through which the line is passing are (2, −7) and (−1, 6). The slope of the line is calculated by the formula written below,
Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
Slope = (6 - ( - 7 ) / ( -1 - 2 )
Slope = 13 / - 3
Slope = -13 / 3
Therefore, the slope of the line passing through the points (2, −7) and (−1, 6) is (13 / 3 ).

Answer:
A. f(x) = (x -3)² -1
B. vertex: (3, -1); axis of symmetry: x=3; x-intercepts: {2, 4}; y-intercept: 8
C. see attached for a graph
Step-by-step explanation:
A. Put the function in vertex form by completing the square. Start by putting parentheses around the terms containing x.
f(x) = (x² -6x) +8
Now, identify the coefficient of x (-6) and square half of that. (-6/2)² = 9. Add this value inside parentheses, and subtract this value outside parentheses.
f(x) = (x² -6x +9) +8 -9
Rewrite the trinomial in parentheses as a square. The constant in the binomial will be the value you squared in the previous step.
f(x) = (x -3)² -1 . . . . . vertex form; a(x -h)²+k for vertex (h, k)
__
B. The vertex and the axis of symmetry can be read from the equation. Here, the vertex is (3, -1). The axis of symmetry is the vertical line through the vertex: x = 3. The x-intercepts are found by solving f(x) = 0.
f(x) = 0
(x -3)² -1 = 0
(x -3)² = 1 . . . . . add the opposite of the 'k' value
x -3 = ±√1 . . . . take the square root. We need both signs.
x = 3 ± 1 . . . . . add 3 to get x by itself. These are the x-intercepts.
x = 3-1 = 2 and x = 3+1 = 4
The x-intercepts are 2 and 4, points (2, 0) and (4, 0).
The y-intercept is the value of f(0). It is the constant in the original form of the function. f(0) = 8 . . . . y-intercept

C. The graph is attached. The various points above are marked, and the axis of symmetry is shown.
