What is the end behavior of the polynomial function?
Drag the choices in to the boxes to correctly describe the end behavior of the function.
Answers
The end behaviours of the functions are
f(x) = 6x⁹ - 6x⁴ - 6: As x ⇒ +∝, f(x) ⇒ +∝ and as x ⇒ -∝, f(x) ⇒ -∝f(x) = -3x⁴ - 6x + 4x - 5: As x ⇒ +∝, f(x) ⇒ -∝ and as x ⇒ -∝, f(x) ⇒ -∝How to determine the end behaviours of the functions?Function 1
The equation of the function is given as
f(x) = 6x⁹ - 6x⁴ - 6
Calculate f(∝) and f(-∝)
So, we have
f(∝) = 6(∝)⁹ - 6(∝)⁴ - 6
Evaluate
f(∝) = ∝ - ∝ - 6
So, we have
f(∝) = ∝
Also, we have
f(-∝) = 6(-∝)⁹ - 6(-∝)⁴ - 6
Evaluate
f(-∝) = -∝ - ∝ - 6
So, we have
f(∝) = -∝
This means that
As x ⇒ +∝, f(x) ⇒ +∝ and as x ⇒ -∝, f(x) ⇒ -∝
Function 2
The equation of the function is given as
f(x) = -3x⁴ - 6x + 4x - 5
Evaluate the like terms
f(x) = -3x⁴ - 2x - 5
Calculate f(∝) and f(-∝)
So, we have
f(∝) = -3(∝)⁴ - 2(∝) - 5
Evaluate
f(∝) = -∝ - ∝ - 5
So, we have
f(∝) = -∝
Also, we have
f(-∝) = -3(-∝)⁴ - 2(-∝) - 5
Evaluate
f(∝) = -∝ + ∝ - 5
So, we have
f(∝) = -∝
This means that
As x ⇒ +∝, f(x) ⇒ -∝ and as x ⇒ -∝, f(x) ⇒ -∝

(-4b³ + b − 1) + (6b - 6) =
Answers
Answer:
-4b^3 + 7b - 7
Step-by-step explanation:
We have to look at terms which look like each other, for example 1b and 6b.
We can add and subtract terms which have the same degree of b.
In this question, we can safely add -1 and -6, and also b and 6b,
which gives us (-4b^3 + b - 1 ) + 6b - 6) = -4b^3 + (1+6)b +( -1 - 6) = -4b^3 + 7b - 7
The three remaining terms all have different degrees of b's (respectively 3, 1, 0), so we can't add those up any further, which tells us that this is the right answer.

By definition:
Congruent figures in geometry are identical in shape and size.
This means that two figures are congruent with each other even if they are rotated, flipped or trasnlated as long as they have the identical shape and size.

We notice that the triangle has the same size and shaped, hence they are congruent. Furthermore we can say that the side BC is congruent to the side ZY and so on.
Using the graph below, write two ordered pairs to show that the equation y = 15x represents the data.
Answers
By using the points (2, 30) and (4, 60) that we can see on the graph, we can see that the linear equation that models the data is:
y = 15*x
How to find the equation that models the data?A general linear equation is of the form:
y = a*x + b
Where a is the slope and b is the y-intercept.
If we know that the line passes through two points (x₁, y₁) and (x₂, y₂), the slope is given by:
a = (y₂ - y₁)/(x₂ - x₁)
In this case we can use two points that appear on the graph, I will use the first two ones:
(2, 30) and (4, 60)
Then the slope is:
a = (60 - 30)/(4 - 2) = 30/2 = 15
Thus, the line is of the form:
y = 15*x + b
To find the value of b we use the point (2, 30), replacing these values we get:
30 = 15*2 + b
30 = 30 + b
30 - 30 = b
0 = b
We conclude that the linear equation that models the data is y = 15*x

10. Sydney wants to buy soda and juice for her birthday party. A bottle of soda costs $1.99 each and a jug of juice costs $2.49 each. If Sydney has $30, what equation could be used to find how many soda bottles and how many jugs of juice she can purchase? let x = let y = Equation
Answers
ANSWER
1.99x + 2.49y = 30
EXPLANATION
A bottle of soda costs $1.99 each and a jug of juice costs $2.49.
Sydney has $30.
Let x be the number of bottles of soda she can get.
Let y be the number of jugs of juice that she can buy.
This means that the cost of x bottles of soda is:
1.99 * x = $1.99x
This also means that the cost of y jugs of juice is:
2.49 * y = $2.49y
The total cost must be equal to $30, so this means that the total cost of bottles of soda and jugs of juice she can purchase is:
1.99x + 2.49y = 30
That is the equation that represents it.

The domain of the graph is [0,14] and the range of the graph is [0, 7]
In this question, we have been given a graph of height of a falling object.
In this graph, x-axis represents the time in seconds and y-axis represents the height in meters.
We know that, the domain of a graph consists of all the input values which are on the x-axis and the range is the set of possible output values, which are shown on the y-axis.
In this graph we can see that the input (time) takes the values between [0, 14] and the output (height) has values in the interval [0, 7]
Therefore, the domain of the graph is [0,14] and the range of the graph is [0, 7]

In order to find the value of x, consider that triangles PQR and PST are similar. Then, you have the following equivalence:
PQ/PS = PR/PT
Where:
PQ = x
PS = 45m

PT = 36m
replace the previous values of the length of the segments and solve for x, just as follow:

Monthly payment = future value / annuity factor
Annuity factor = {[(1+r)^n] - 1} / r
Where:
r = monthly interest rate = 4.8% / 12 = 0.4%n = number of periods = number of compounding x number of years: 12 x 25 = 300$610,823.48 ÷ [{(1.004^300) - 1} / 0.004] = $1,056.71

Match the two lines that are parallel and the two lines that are perpendicular. Then, match the equations.
Answers
Step-by-step explanation:
A and C are parallel. equations G and E.
B and D are perpendicular (standing at a right angle = 90° to each other). equations F and H.
parallel means that both lines have the same slope.
the slope is the factor a of x when the equations look like
y = ax + b (slope-intercept form)
or
y - y1 = a(x - x1) (point-slope form)
"a" being the slope, b being the y-intercept (the y- value when x = 0), (x1. y1) being a point on the line.
the slope is specified as ratio (y coordinate difference / x coordinate difference) when going from one point to another.
the perpendicular slope to y/x is the upside down ratio and the sign is flipped.
e.g. the perpendicular slope to 5/4 is -4/5.
equation E is already in point-slope form.
the slope is 2/3, and the point (-9, -2) must be on the line.
only one line goes through the point (-9, -2) : C.
equation H is already in slope-intercept form.
the slope is 3/2, and the y-intercept is 5, meaning the line goes through the point (0, 5).
only one line goes through that point : D
equation F
2x + 3y = -21
3y = -2x -21
y = (-2/3)×x - 7
the slope is -2/3, which is perpendicular to 3/2 (equation H).
the y-intercept is -7, meaning the line goes through the point (0, -7).
only one line goes through that point : B
equation G
-2x + 3y = -6
3y = 2x - 6
y = (2/3)×x - 2
the slope is 2/3 (parallel to equation E).
the y-intercept is -2, meaning the line goes through the point (0, -2).
only one line goes through that point : A
