Question 6
What does the relationship between the slopes of corresponding line segments in the prelmage and in the image imply about the line segments?
In other words, what do you know about two or more line segments that have the same slope?
Therefore, when we draw the slope of line then the slope of corresponding line segment in the preimage and image apply about the line segments both are equal.
What is the slope of line?
The slope of a line is its vertical change divided by its horizontal change, also known as rise over run.
When the two or more line segments that have the same slope are parallel to each other.So, the lines graphed by a system of equation is also same slope which would be parallel to each other.
Hence, when we draw the slope of line then the slope of corresponding line segment in the preimage and image apply about the line segments both are equal.

Answer:
Length of the ladder = 9.5 feet
Step-by-step explanation:
Point A of ladder AC is at 9 ft from the ground and point C is 3 feet from the base of the wall,
AB = 9 feet
BC = 3 feet
By applying Pythagoras theorem in the right triangle,
AC² = AB² + BC²
AC² = 9² + 3²
AC² = 81 + 9
AC = √90
= 9.486 feet
≈ 9.5 feet
Therefore, length of the ladder is 9.5 feet.

A line passes through the point 2,1 and has a slope of -3/5. Write an equation for this line
Answer:
y = -3/5x + 1.3
Step-by-step explanation:
y = mx + b
m: slope
b: y-intercept
First, let's substitute in the values.
Point: (2, 1)
Slope: -3/5
y = mx + b
(1) = (-3/5)(2) + b
1 = -0.3 + b
1 + 0.3 = -0.3 + b + 0.3
b = 1.3
Now, let's add the slope and y-intercept to the equation.
y = mx + b
m = -3/5
b = 1.3
y = -3/5x + 1.3

c bc 3x>21 is x>7
the smallest whole number out of the multiple choice answer that fits into the solution is 8
Answer:
C. 8
Step-by-step explanation:
To answer you must first solve the inequality, do this by dividing both sides by 3. [tex]\frac{3x}{3} > \frac{21}{3}[/tex], which simplifies to x > 7. This means that x must be greater than 7 without being 7 because the inequality does not use the "or equal to" sign. Therefore, 8 must be the correct answer because it is the smallest whole number that is larger than 7.
Each square on a grid represents one unit on each side.
Calculate the slope of graph D. Explain or show your reasoning.
Answer:
Slope = -4
Step-by-step explanation:
The slope is negative because the line is going down.
The line goes down 4 times and goes right once = 4
The required slope of the given graph would be - 4 which is a negative slope.
What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
The graph is given in the question
Each square on a grid represents one unit on each side.
We have to determine the slope of the given graph D
According to the given graph, we take two points (4, 12) and (7, 0)
The slope of a line is defined as the gradient of the line.
It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Consider two points on a line—Point 1 and Point 2. Point 1 has coordinates (x₁,y₁) and Point 2 has coordinates (x₂, y₂)
Slope m = (0 - 12)/(7 -3 )
Slope m = -12/3
Slope m = -4
Thus, the required slope of the given graph would be - 4

A team is ordering sweatshirts and sweatpants for its players. Each sweatshirt costs $34 and each pair of sweatpants costs $15. Write an algebraic expression to represent the total cost if want sweatshirts and y players want sweatpants.
Answer:
34+15y
Step-by-step explanation:
Let x players want a sweatshirt and y players want sweatpants.
Each sweatshirt costs $34 and each pair of sweatpants costs $15.
Cost of sweatshirt = 34x
Cost of sweatpants = 15y
Total cost = cost of sweatshirt + cost of sweatpants
= 34x+15y
Hence, the total cost is "34x+15y".

given a-2b=8, 4a+3b= 21; prove b= -1
please give a step by step answer
For the system of the equation given we have proven that b = -1.
Given that,
a - 2b = 8
4a + 3b = 21
To prove b= -1
The equation is the relationship between variables and is represented as y =ax +b is an example of a polynomial equation.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
a - 2b = 8 - - - - - - - (1)
4a + 3b= 21 - - - -- - - (2)
From equation 1
a = 8 + 2b
put a in equation 2
4 (8 + 2b) + 3b = 21
32 + 8b + 3b = 21
11b = 21 - 32
11b = -11
b = -1
Hence proved.
Thus, for the system of the equation given, we have proven that b = -1.

In a research lab, a cell biologist is growing a strain of bacteria under two different conditions. Culture A had an initial population of 200 and doubles every hour. Culture B had an initial population of 819200 but has been contaminated. Its population is now decreasing by half every hour. When will the two cultures have an equivalent population? Solve using an exponential equation.
Answer:
They will have the same population after 6 hours
Step-by-step explanation:
The general exponential equation format for this is;
P = P_o(e^(kt))
For Culture A, we are told that it had an initial population of 200 and doubles every hour.
Thus;
After 1 hour, P = 400
After 2 hours, P = 800
After 3 hours, P = 1600
Thus;
At t = 1, we have;
400 = 200(e^(k × 1))
400/200 = e^(k)
e^(k) = 2 - - - (eq 1)
At t = 2, we have;
800 = 200(e^(k × 2))
800/200 = e^(2k)
e^(2k) = 4 - - - (eq 2)
To find k, let's divide eq 1 by eq 2.
(e^(2k))/e^(k) = 4/2
e^(2k - k) = 2
e^(k) = 2
k = In 2
k = 0.6931
Thus;
P = 200e^(0.6931t)
For Culture B, we are told that it had an initial population of 819200 but has been contaminated. Its population is now decreasing by half every hour.
Thus;
After 1 hour, P = 409600
After 2 hours, P = 204800
After 3 hours, P = 102400
Thus;
At t = 1, we have;
409600 = 819200(e^(k × 1))
409600/819200 = e^(k)
e^(k) = 0.5 - - - (eq 1)
At t = 2, we have;
204800 = 819200(e^(k × 2))
204800/819200 = e^(2k)
e^(2k) = 0.25 - - - (eq 2)
To find k, let's divide eq 1 by eq 2.
(e^(2k))/e^(k) = 0.25/0.5
e^(k) = 0.5
k = In 0.5
k = -0.6931
Thus;
P = 819200(e^(-0.6931t))
We want to find the time when the 2 cultures will have the same population. Thus;
200e^(0.6931t) = 819200(e^(-0.6931t))
Arranging, we have;
(e^(0.6931t))/(e^(-0.6931t)) = 819200/200
e^(0.6931t - (-0.6931t) = 4096
e^(1.3862t) = 4096
1.3862t = In 4096
1.3862t = 8.3178
t = 8.3178/1.3862
t ≈ 6 hours
What is the value of x for the equation 4x – 2y = 6 if y= -3?

4. Bikes A and B are traveling on perpendicular roads. At the same time, bike A is
leaving the intersection at a rate of 2 feet per second and bike B is leaving the
intersection at 3 feet per second. How fast is the distance, in feet per second between
them changing after 5 seconds?
Answer:
[tex]\sqrt{13}[/tex]
The rate of change of distance between two cars at the given time is required.
The required rate of change is [tex]\sqrt{13}[/tex] feet/s
Rate of changea = Distance covered in 5 s by bike A = [tex]2\times 5=10\ \text{feet}[/tex]
b = Distance covered in 5 s by bike B = [tex]3\times 5=15\ \text{feet}[/tex]
c = Distance between A and B in 5 s = [tex]\sqrt{10^2+15^2}=5\sqrt{13}\ \text{feet}[/tex]
Applying Pythagoras theorem
[tex]a^2+b^2=c^2[/tex]
Differentiating with respect to time
[tex]2a\dfrac{da}{dt}+2b\dfrac{db}{dt}=2c\dfrac{dc}{dt}\\\Rightarrow \dfrac{dc}{dt}=\dfrac{a\dfrac{da}{dt}+b\dfrac{db}{dt}}{c}\\\Rightarrow \dfrac{dc}{dt}=\dfrac{10\times 2+15\times 3}{5\sqrt{13}}\\\Rightarrow \dfrac{dc}{dt}=\sqrt{13}\ \text{feet/s}[/tex]
