Slope = -5
Step-by-step explanation:
(x,y) ⇒ (13,11), (14,6), (15,1), (16,-4)
Pick any two points:
(x₁, y₁) and (x₂, y₂) ⇒ (15, 1) and (16, -4)
Use the slope formula:
⇒ y₂ - y₁/x₂ - x₁
⇒ -4 - 1/16 - 15
⇒ -5/1 = -5
Thus, the slope is -5.

a bus travelled 63 km in first hour 60 km in second hour and 57 km in third hour what was te Average distance covered in one hour
Answers
The average speed is the ratio of the total distance to the total time. Then the average distance covered in one hour by the bus is 60 kilometers.
What is speed?The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
[tex]\rm Speed = \dfrac{Distace }{Time }[/tex]
A bus traveled 63 km in the first hour 60 km in the second hour and 57 km in the third hour.
Then the average speed will be
[tex]\rm Average \ speed = \dfrac{Total \ distace }{Total \ time }\\\\\\Average \ speed = \dfrac{63 + 60 +57}{1+1+1}\\\\\\ Average \ speed = \dfrac{180}{3}\\\\Average \ speed = 60 \ km/h[/tex]
The average distance covered in one hour by the bus is 60 kilometers.

[tex]\displaystyle \large{y=3x+5}[/tex]
To find an inverse of function, swap the position of x and y:
[tex]\displaystyle \large{x=3y+5}[/tex]
Then solve or simplify the equation in term of y:
[tex]\displaystyle \large{x-5=3y}\\\displaystyle \large{\frac{x-5}{3}=y}\\\displaystyle \large{y=\frac{1}{3}x-\frac{5}{3}}[/tex]

Summary
An inverse function is a function that swaps the position of domain and range, defined as notation [tex]\displaystyle \large{f^{-1}(x)}[/tex] or [tex]\displaystyle \large{y^{-1}}[/tex] generally. When finding an inverse function, make sure to swap position of range and domain, if given the interval.
Only one-to-one functions may have an inverse — multiple-to-one can not have an inverse such as quadratic function or any even-degree polynomial functions.

Which of the following functions will represent $500 placed
into a mutual fund yielding 10% per year for 4 years.
• A = 500(.10)^4
• A = 500(1.1)^4
• A = 500(4)(.10)
• A = 500(1.04)^10
Answers
Answer:
the answer is the first one
Step-by-step explanation:
The functions will represent $500 placed into a mutual fund yielding 10% per year for 4 years is A = 500(1.1)^4
what is Compound Interest?In order to compute compound interest, multiply the principle of the original loan by the annual interest rate multiplied by the number of compound periods minus one. You will then be left with the principal amount of the loan plus compound interest.
given:
P= $500
First, convert R as a percent to r as a decimal
r = R/100
r = 10/100
r = 0.1 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 500.00[tex](1 + 0.1/1)(1)^4[/tex]
A = 500.00[tex](1.1)^4[/tex]
A = $732.05
Hence, the functions will represent $500 placed into a mutual fund yielding 10% per year for 4 years is A = 500(1.1)^4

Which statements about the system are true? Check all that apply.
y= -13x - 4
3y-x= -7
a
Both lines have the same y–intercept.
b
The system consists of parallel lines.
c
The equations represent the same line.
d
The system has one solution.
e
Both lines have the same slope.
Answers
Answer: D
Step-by-step explanation:
To compare the two lines, we want to a=make sure that they are in the same form.
3y-x=-7 [add both sides by x]
3y=x-7 [divide both sides by 3]
y=1/3x-7
Now that the equations are in the same form, we can compare them.
In order for the equations to have the same y-intercept, the "b" must be the same. The y-intercept for the first equation is -4, while the y-intercept for the second equation is -7. Therefore, A is not the answer.
If the lines are parallel, they must have the same slope. Parallel lines NEVER touch or cross, hence the slope has to be the same. The slope for the first equation is -13, while the slope for the second equation is 1/3. Therefore, B is not the answer.
We know that E is not the answer because the paragraph above proved that the slope are not equal.
We also know that the equations do not represent the same line. If they are the same line, the equations would be identical.
We know that D is the correct answer. A system of linear equaitons can only have ONE solution. We set the equations equal to each other to find the solution. The intersection point is the solution.
Therefore, we know that D is the right answer.

Line a is parallel to line b. If the measure of <7 is 114 what is the measure of <4?
Answers
Using opposite by the same vertex and supplementary angles, it is found that the measure of angle 4 is of 66º.
What are opposite by the same vertex and supplementary angles?When two parallel lines are cut by a transversal, angles that are opposite in a vertex are congruent, that is, they have the same measure.When two angles are supplementary, the sum of their measures is of 180º.In this problem, angles 5 and 7 are opposite by the same vertex, hence:
m<7 = m<5 = 114º.
Angles 4 and 5 are supplementary, hence:
m<4 + m<5 = 180º.
m<4 = 66º.
The measure of angle 4 is of 66º.

The length of the rectangle is 18 cm, and the width is 24 cm as per the concept of perimeter.
Let the length of the rectangle be 3x and the width be 4x, where x is a common factor.
The perimeter of a rectangle is given by the formula:
Perimeter = 2 × (Length + Width)
Given that the perimeter is 84 cm, we can write the equation as:
84 = 2 × (3x + 4x)
Now, let's solve for x:
84 = 2 × 7x
42 = 7x
x = 42 / 7
x = 6
Now that we have the value of x, we can find the length and width of the rectangle:
Length = 3x = 3 × 6
= 18 cm
Width = 4x = 4 × 6
= 24 cm
Therefore, the length of the rectangle is 18 cm, and the width is 24 cm. The length and width are in the ratio 3:4, and the perimeter of the rectangle is indeed 84 cm.
