But if it means what I think it means, a figure could explain it better.
o Here is B(2,0)
o Here is P(-1,-2.4)
Here is A(-3,-4)o
There is a straight line from the bottom point (A) to the top point (B) and its equation is y=0.8x-1.6
The point (-1, -2.4) lies on the line from A to B, but not in the center.
If you find the distance from A to P, then find the distance from P to B, you can make a ratio of the two lengths.
AP = sqrt[(-1-(-3))2+(-2.4-(-4))2] = sqrt[22+1.62] = sqrt[6.56] = 2.561
PB = sqrt[(-1-2)2+(-2.4-0)2]=sqrt[(-3)2+(-2.4)2] = sqrt[14.76] = 3.842
So the two parts are in the ratio 2.561 : 3.842 (AP : PB) or 2.561/3.842 = 0.66658 = 2/3 (approx)
The point P partitions AB into two segments with ratio 2/3
Not sure if that what you mean because there isn’t a lot of context but hope that helped, have a great day

Solve the system of linear equations by substitution. x=16−4y 3x+4y=8
Answers
Answer:
Solution: (-4,5)
Step-by-step explanation:
x=16-4y
3x+4y=8
-----
The 1st equation tells you x = 16-4y
---
Substitute that into the 2nd equation
and solve for "y":
3(16-4y)+4y = 8
48 - 12y + 4y = 8
-8y = -40
---
y = 5
---
Solve for "x"
x = 16-4y
x = 16-4*5
x = 16-20
x = -4
The given system of equations has (-4, 5) as its solution.
What is a expression? What is a mathematical equation?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.We have the following system of equations -
x = 16 - 4y
3x + 4y = 8
Now, we can write -
3x + 4y = 8
3(16 - 4y) + 4y = 8
48 - 12y + 4y = 8
40 = 8y
y = 5
Then, we can write -
x = 16 - 20
x = - 4
Therefore, the given system of equations has (-4, 5) as its solution.

Charlotte works in a calling center making appointments for a local lawn care service. She earns $40 each full workday plus an additional $2 for each appointment that she schedules. Today, Charlotte needs to earn at least $75. Write an inequality to describe this situation. In two or more complete sentences, describe the solution set of this inequality and what it means for Charlotte.
Answers
x = number of appointments
y = total amount earned in dollars
The total earnings equation is y = 2x+40
The 2x is from her earning $2 per appointment. If she makes x of them, then she earns 2x dollars. This is on top of the $40 from working the full day.
She wants to earn at least $75. This means she wants to earn $75 or more.
This means,
[tex]y \ge 75\\\\2x+40 \ge 75\\\\2x \ge 75-40\\\\2x \ge 35\\\\x \ge \frac{35}{2}\\\\x \ge 17.5[/tex]
Since x is the number of appointments, and we can't have a fractional number of appointments, we must round up to x = 18. This is the lowest number of appointments she can do and earn $75 or larger.
If x = 17, then
y = 2x+40 = 2*17+40 = 34+40 = 74
which is not 75 or larger
But if x = 18, then
y = 2x+40 = 2*18+40 = 36+40 = 76
which is larger than 75, so we've cleared the hurdle.
We can say the solution set is [tex]x \ge 18[/tex] where x is a whole number. So she could book x = 18, x = 19, x = 20, x = 21, etc as the number of appointments to reach her goal.
In summary, she must schedule at least 18 appointments to earn $75 or more.
Since she makes $2 for every appointment she makes we would need to use 40+2n so she would get $2 per appointment no matter how many appointments she makes. Also, we wouldn't use an equal sign because they didn't say she needed to earn exactly $75. They said she needed to earn "at least" $75. At least means equal to or greater than ≥. So the inequality would be 2n+40≥75. PRO TIP: Any time it asks you to write an inequality you will use either <, >, ≤, or ≥ not an =.An equation uses =, an inequality uses the other symbols

D. The samples are independent because there is not a natural pairing between the two samples.
Answers
Answer:
D. The samples are independent because there is not a natural pairing between the two samples
explanation:
Independent samples do not affect each other as each group is selected randomly. They are common in statistical analysis, example: when there is a control group and an experimental group and the subjects for each group are different. In the above example, the samples do not depend on each other. There are 90 randomly selected married men in one group and 90 randomly selected married women in the other. The subjects are different in the two groups and so they do not affect each other. This is unlike dependent/paired samples where for example same subjects are used before and after a medication and therefore each group affects the other.

state the slope and a point on the line y - 18 = 71.3(x +98)
explain how you got your answer
Answers
Answer:
slope = 71.3 and a point (0, 7005.4)
Step-by-step explanation:
the slope in an equation of the form y = mx+b, m is the slope so multiply 71.3 through the brackets and then add 18 to both sides and that is the equation in y=mx+b format and 71.3 is the slope and b os the y-intercept which turns out b=7005.4 and since its a y-intercept x = 0
Answer:
The slope is 71.3 and the point on the line is (h, k): (-98, 18)
Step-by-step explanation:
y - 18 = 71.3(x +98) is to be solved for the slope and a point on the line represented by this equation.
Refer to the point-slope formula y - k = m(x - h), where (h, k) is a point on the ine and m is the slope of the line.
Comparing y - 18 = 71.3(x +98) to
y - k = m(x - h),
we readily see that k = 18, h = -98 and m = 71.3
The slope is 71.3 and the point on the line is (h, k): (-98, 18)

LaTeX: g\left(x\right)=4x^2 g ( x ) = 4 x 2
LaTeX: g\left(x\right)=\left(x+4\right)^2 g ( x ) = ( x + 4 ) 2
LaTeX: g\left(x\right)=x^2+4 g ( x ) = x 2 + 4
LaTeX: g\left(x\right)=\left(x-4\right)^2 g ( x ) = ( x − 4 ) 2
Answers
Answer:
C. g(x) = x²+4
Step-by-step explanation:
Given the parabola function f(x) = x²
Translating the function up by 4 means adding the constant value of +4 to the function since it's translated along the positive y axis. The resulting function g(x) will be x²+4
Hence the correct answer is g(x) = x²+4. Option C is correct.

Rectangle ABCD is in the coordinate plane. Which of the following is a valid definition of a reflection of rectangle ABCD?
A. Every point X on ABCD is mapped to a new point X′ such that each length from X toX′ is the same.
B. Every point X on ABCD is mapped to a new point X′ such that the distance from X to the line of reflection is the same as the distance from X′ to the line of reflection.
C. Every point X on ABCD is mapped to a new point X′ such that the coordinates of X′ are opposites of the coordinates of X.
D. Every point X on ABCD is mapped to a new point X′ such that one coordinate of X′ is the same as in X and the other coordinate of X′ is the opposite of the other coordinate in X.
Answers
The definition of a reflection of rectangle ABCD is option D:
"Every point X on ABCD is mapped to a new point X' such that one coordinate of X' is the same as in X, and the other coordinate of X' is the opposite of the other coordinate in X".
When a reflection occurs, each point on the original shape is mapped to a new location on the reflected shape.
Option A states that every point X on ABCD is mapped to a new point X' such that each length from X to X' is the same. This definition does not capture the essence of a reflection because it doesn't consider the relationship between the original shape and its reflection.
Option B states that every point X on ABCD is mapped to a new point X' such that the distance from X to the line of reflection is the same as the distance from X' to the line of reflection.
Option C states that every point X on ABCD is mapped to a new point X' such that the coordinates of X' are opposites of the coordinates of X.
Option D correctly captures the nature of a reflection. This states that each point X on ABCD is mapped to a new point X' where one coordinate of X' is the same as in X, and the other coordinate of X' is the opposite of the other coordinate in X.
Therefore, option D is the valid definition of a reflection of rectangle ABCD.
