Answer:
[tex]3r^{4}s^{5}\\-r^{4}s^{6}[/tex]
Step-by-step explanation:
The standard form of a polynomial is when its term of highest degree is at first place.
In this case, we have two variables. The grade of each term is formed by the sum of its exponents. That means both given terms have a degree of six. So, the right answers must have a higher degree.
Therefore, the right answers are the second and third choice, because their degrees are 9 and 10 respectively.

Answer:
A.I, III, and IVStep-by-step explanation:
The slope-intercept form of an equation of a line:
[tex]y=mx+b[/tex]
m - slope
b - y-intercept → (0, b)
If m > 0, then the function is increased
If m < 0, then the function is decreased
We have
[tex]m=\dfrac{2}{3}>0[/tex] - the function is increased
[tex]b=-4[/tex] - the y-intercept is -4 → (0, -4)
Therefore the line passes through III, IV and I quadrant.
========================================
<, ≤ - shaded region below the line
>, ≥ - shaded region above the line
========================================
We have [tex]y\leq\dfrac{2}{3}x-4[/tex] → ≤ - shaded region below the line.
Therefore the inequal the inequality exist in I, III and IV quadrant.
Look at the picture.

D. (4, –1)
Answer: You can use a graphing calculator in the future
(2,3)
A
Answer: A(2,3)
Step-by-step explanation:
To solve the system of equations;
y=-1/2x+4 and y = 2x – 1
y=-1/2x+4 ----------(1)
y = 2x – 1 -----------(2)
Lets substitute equation 2 in equation 1
2x - 1 = -1/2x+4
Collect like term
(We move the x variables from the right -hand side of the equation to the right-hand side of the equation to the right-hand-side of the equation and then move the constants to the right-hand side of the equation)
2x + 1/2x = 4 + 1
5x/2 = 5
To get the value of x, we will multiply both-side of the equation by 2/5
5x/2 × 2/5 = 5 × 2/5
(On the left-hand side of the equation, the 5/2 will cancel out the 2/5 leaving us with x and on the right-hand side of the equation 5 will cancel out 5 leaving us with 2)
x = 2
Substitute x =2 in equation (2)
y = 2x - 1
y = 2(2) - 1
y = 4 -1
y =3
The solution to the system of the equations is x=2 and y=3
Therefore the answer is A(2,3)
The graph of f(x) = |x| is transformed to g(x) = [X + 11-7. On which interval is the function decreasing?
Answer:
The interval of the decreasing function is (-∞ , -1) ⇒ g(x)
The interval of the decreasing function is (-∞ , 0) ⇒ f(x)
Step-by-step explanation:
* Lets explain how to solve it
- Decreasing function means a function with a graph that moves
downward as it is followed from left to right.
- For example, any line with a negative slope is decreasing function
- Lets look to the attached graph to understand the meaning of the
decreasing function
∵ f(x) = IxI ⇒ green graph
∵ g(x) = Ix + 1I - 7 ⇒ purple graph
- From the graph f(x) translated 1 unit to the left and 7 units down to
form g(x)
- The domains of f(x) and g(x) are all real numbers {x : x ∈ R}
- The range of f(x) is {y : y ≥ 0}
- The range of g(x) is {y : y ≥ -7}
# For f(x)
- The slope of the green line from (-∞ , 0) is negative
- The slope of the green line from (0 , ∞) is positive
# For g(x)
- The slope of the purple line from (-∞ , -1) is negative
- The slope of the purple line from (-1 , ∞) is positive
∵ The line with negative slope represent decreasing function
∴ The interval of the decreasing function is (-∞ , -1) ⇒ g(x)
∴ The interval of the decreasing function is (-∞ , 0) ⇒ f(x)
The function g(x) = |x+11|-7 is a transformed absolute value function, which is decreasing on the interval (-infinity, -11) due to the horizontal shift to the left by 11 units.
The question is asking about the transformation of the absolute function f(x) = |x| into a new function g(x). The function provided, g(x) = |x+11|-7, is a transformed version of f(x) where the graph has been shifted horizontally and vertically. To determine on which interval g(x) is decreasing, we need to consider the properties of the absolute value function and its transformations.
The graph of the standard absolute value function, f(x) = |x|, is shaped like a 'V', increasing for x > 0 and decreasing for x < 0. When we introduce a horizontal shift to the function (such as adding 11 to x), this shifts the vertex of the 'V' horizontally. For g(x), the graph is shifted to the left by 11 units due to the '+11' inside the absolute value. Therefore, the function will be decreasing on the interval (-infinity, -11) since the function will decrease to the left of the vertex (which is now located at x = -11). The vertical shift (subtracting 7) simply moves the graph down but does not affect the intervals of increasing or decreasing behavior.

What is the slope of the line represented by the equation y = x – 3? –3 3
Answer:
None of then, the slope is 1
Step-by-step explanation:
We have to use the general equation for lines, that is:
[tex]y=mx+b[/tex]
where 'm' is the slope (by comparison)
So, we only need to compare your equation ([tex]y=x-3[/tex]) with the general one.
We can see that m=1, b=-3
So our slope turns out to be equals to 1

You need to catch two different buses to get to the shops Bus 1 is due to leave at 2 o'clock and arrive at 2.30. You have a half hour wail between getting off the first bus and getting on the second bus.
Bus 2 is due to arrive at the shops at 3.15.
(a) What time is bus 2 scheduled to leave? Bus 2 leaves 15 minutes early
(b) What time does it leave? () What time does it anive?
Bus 1 is 15 minutes late.
(c) What time does it arrive?
Answer:
rxch.ace_
Step-by-step explanation:
Final answer:
Bus 2 is scheduled to leave at 3:00 pm, but if it leaves 15 minutes early, it departs at 2:45 pm and arrives at the shops at 3:00 pm. If Bus 1 is 15 minutes late, it arrives at 2:45 pm, the same time Bus 2 leaves, preventing the transfer.
Explanation:
To solve the question regarding bus schedules and arrival times, let's break down each part of the problem step by step.
Part (a): Scheduled Departure Time of Bus 2
Bus 1 arrives at the first stop at 2:30 pm. There is a half-hour wait, so the earliest you can board Bus 2 is at 3:00 pm. Since Bus 2 arrives at the shops at 3:15 pm, and it leaves 15 minutes before its scheduled arrival time, Bus 2 is scheduled to leave at 3:00 pm.
Part (b): Bus 2 Leaves Early
Bus 2 is supposed to leave 15 minutes early. If its scheduled departure was 3:00 pm, it actually leaves at 2:45 pm. Since it leaves 15 minutes early and the travel time remains unchanged, Bus 2 would still arrive at 3:00 pm at the shops.
Part (c): Bus 1 is Late
Bus 1 is 15 minutes late. Instead of leaving at 2:00 pm, it leaves at 2:15 pm and arrives at the first stop at 2:45 pm. Since Bus 2 leaves at 2:45 pm, you would not be able to transfer from Bus 1 to Bus 2 since their arrival and departure times coincide.

In ∆ABC, m<A = 72 and m<B = 83. What is the measure of <C?
Answer:
25 degrees.
Step-by-step explanation:
The 3 angles in a triangle add up to 180 degrees therefore:
m < C = 180 - 72 - 83
= 180 - 155
= 25 degrees.
Answer:
25
Step-by-step explanation:
Theorem:
The sum of the measures of the interior angles of a triangle is 180 degrees.
The theorem is can be written as the equation below.
m<A + m<B + m<C = 180
We know the measures of angles A and B, so we substitute the values for those measures, and we solve for the measure of angle C.
72 + 83 + m<C = 180
Add like terms on the left side.
155 + m<C = 180
Subtract 155 from both sides.
m<C = 25
Answer: m<C = 25
Should it be facing left or right ?
Answer:
Facing Right
Step-by-step explanation:
Given inequalities are:
4-x≤-1
Subtracting 4 from both sides
4-x-4≤-1-4
-x≤-5
Multiplying both sides with -1. Multiplying with a negative number changes the sign of the inequality
So,
x≥5
Second Inequality:
2+3x≥17
Subtracting 2 from both sides
2+3x-2≥17-2
3x≥15
Dividing both sides by 3
x≥5
Union of both solutions:
x≥5 ∩ x≥5
=> x≥5
Hence the solution will be facing right on the number line towards all numbers greater than or equals to 5 ..
Angles 4 and 5 form what type of angles?
complementary angles
supplementary angles
vertical angles
obtuse angles
Answer:
the answer will be verticle angles
Step-by-step explanation:
∠4 and ∠5 form vertical angles.
What is vertical angles?When two lines intersect each other, then non-adjacent opposite angles are called vertical angles.
Vertical angles are always equal in measurement.
If line AB and CD intersect each other at point O, ∠AOC and ∠BOD are vertical angles, similarly, ∠AOD and ∠BOC are also vertical angles.
Here lines 1 and 2 intersect each other.
So ∠4 and ∠5 are formed which are non-adjacent and opposite also.
Therefore ∠4 and ∠5 form vertical angles.

The length of a rectangle is three times its width. The perimeter is 160 cm. What is the number of square centimeters in the area of the rectangle?
Answer:
1200 cm²
Step-by-step explanation:
width = x cm
length = 3x cm
perimeter = 160 cm
2(x + 3x) = 160
4x = 160/2
4x = 80
x = 80/4
x = 20 cm - width
length = 3x = 3 · 20 = 60 cm
Area = length · width = 60 · 20 = 1200 cm²
The rectangle's width is 20 cm and its length is 60 cm. Thus, the area of the rectangle is 1200 square centimeters.
Explanation:We are given that the length of a rectangle is three times its width. Let's denote the width as 'w'. Consequently, the length would be '3w'.
The perimeter of a rectangle is given by the formula: 2*(length + width). Given that the perimeter is 160 cm, we can substitute our variables into the formula: 2*(w + 3w) = 160. This simplifies to 8w = 160. Therefore, the width (w) equals 20 cm, and the length is 60 cm (3w).
The area of a rectangle is calculated by multiplying its length and width. Hence, the area of our rectangle is: 60 cm * 20 cm = 1200 square centimeters.
