What is the inverse of the equation y = 3x + 2?
Answer: y = (x-2)/3
This is equivalent to y = (1/3)x - 2/3
=================================================
To get this answer, we need to swap x and y in the original equation. Then solve for y to get the inverse.
y = 3x+2
x = 3y + 2 ... x and y swapped
x-2 = 3y
3y = x-2
y = (x-2)/3
y = x/3 - 2/3
y = (1/3)x - 2/3
This final equation has slope 1/3 and y intercept -2/3

Answer:
Graph (C)
Step-by-step explanation:
To find whether the graph\table represents a relationship or a function we have to analyze the input-output values given.
Graph A.
In this graph for every input value (x-value) there are two output values (y-values).
For x = -2, y = -2, 2
So the graph doesn't represent a function.
Graph B.
For every x value there are two y-values
For x = -5, y = -3, 3
So the graph doesn't represent a function.
Graph C.
For every input value there is a different y-value.
Therefore, graph represents a function.
Graph D.
In this graph for x = 3, y = 1, 2, 3, 4
For one value of x, there are four values of y.
Therefore, graph doesn't show the relationship.
Graph C has exactly one output (y-value) corresponding to each input (x-value), therefore, the graph that represents a functional relationship is: Graph C.
What is a Functional Relationship?A functional relationship is a relationship whereby every input in the relation has exactly one possible output.
In other words, a functional relationship must have exactly one output that corresponds to each of the input values.
Thus, graph C has exactly one output (y-value) corresponding to each input (x-value), therefore, the graph that represents a functional relationship is: Graph C.

The ratio of the number of people who
threw tomatoes onto the stage to the
number of people who threw cabbage was
8 to 9. If 168 people threw tomatoes onto
the stage, how many threw cabbage?
Answer:
189
Step-by-step explanation:
ratio is 8:9
multiply ratio by 21 to get 168:189
The number of people who threw the cabbage should be considered as the 189 when the ratio is given.
Calculation of the number of people who threw the cabbage:Since
The ratio of the number of people who threw tomatoes onto the stage to the number of people who threw cabbage was 8 to 9.
And, 168 people threw tomatoes onto the stage

Gabrielle is 11 years younger than Mikhail. The sum of their ages is 77 What is Mikhail's age?
Answer:
44
Step-by-step explanation:
The relations can be written using one variable to represent Mikhail's age: m. Gabrielle's age is (m-11), so the sum of their ages is ...
m +(m -11) = 77
2m = 88 . . . . . . add 11
m = 44 . . . . . . . divide by 2
Mikhail's age is 44.
__
Additional comment
Gabrielle is 33.
You could solve this using two variables:
m - g = 11m + g = 77Adding these two equations gives the one we have above:
2m = 88
m = 44
__
You may have noticed we are given the sum and the difference of the two ages. The older Mikhail's age is half the sum of those two numbers. The younger Gabrielle's age is half their difference: (77 -11)/2 = 33. This "half the sum, half the difference" solution is the generic solution to a "sum and difference" problem.
Gabrielle : 33
Mikhail : 44
Explanation:
Let Mikhail's age be x
And Gabrielle's age be y.
======================
Gabrielle is 11 years younger than Mikhail
y = x - 11 [ equation 1 ]
sum of their ages is 77
x + y = 77 [ equation 2 ]
Insert equation 1 into 2
x + x - 11 = 77
2x = 77 + 11
2x = 88
x = 44
Therefore, the age of Mikhail is 44
Find Gabrielle's age:
y = x - 11
y = 44 - 11
y = 33
Therefore, the age of Gabrielle is 33
Find the total amount of an investment of $413.99 compounded at 4.25% for 8.5 years
Answer:
Present Value = $413.99
Interest rate = 4.25%
Years = 8.5 years
Future value = P(1+I)^n
Future value = $413.99*(1+0.425)^8.5
Future value = $413.99*(1.0425)^8.5
Future value = $413.99*1.4244478
Future value = $589.707144722
Future value = $589.71
The total amount to be earned as a result of the investment for 8.5 years is $589.71.

a map has a scale of 1/2 inches:12 miles if the actual distance between the cities is 480 miles how far apart are they on the map
Answer:
20 inches
Step-by-step explanation:
Since there are 480 miles in total, we have to divide it by 12 so we can see how many half inches that would be.
480÷12 = 40
That would mean you can fit forty 12's in 480. Since 12 miles equals 1/2, you would multiply it by 40.
1/2 × 40 =20
This means that the distance between the cities on the map would be 20 inches.

A boat is trying to determine its speed, in feet per second. The boat spots a 245 foot tall lighthouse at point A at an angle of elevation of 12°. Five minutes later it arrives at point B after traveling in a straight line towards the light house. The angle of elevation is now 28°. What is the boat’s speed to the nearest foot per minute.
Using the slope concept, it is found that the boat traveled at a speed of 138 feet per minute.
What is a slope?The slope is given by the vertical change divided by the horizontal change, and it's also the tangent of the angle of depression.
At point A, we have that the vertical change is of 245 ft with an angle of 12º, hence the position in feet is given by:
[tex]\tan{12^\circ} = \frac{245}{x_A}[/tex]
[tex]x_A = \frac{245}{\tan{12^\circ}}[/tex]
[tex]x_A = 1152.6[/tex]
At point B, we have an angle of 28º, hence:
[tex]\tan{28^\circ} = \frac{245}{x_B}[/tex]
[tex]x_B = \frac{245}{\tan{28^\circ}}[/tex]
[tex]x_B = 460.7[/tex]
The distance in feet the boat traveled in 5 minutes was of:
[tex]d = x_A - x_B = 1152.6 - 460.8 = 691.8[/tex]
Velocity is distance divided by time, hence:
v = 691.8/5 = 138.
The boat traveled at a speed of 138 feet per minute.

Can you find the perimeter of each rectangle and type the correct code? Please remember to type in ALL CAPS with no spaces. *
Answer:
CEFA
Step-by-step explanation:
The perimeter of a rectangle is the sum of the lengths of the 4 sides. A rectangle has two lengths of equal size and two width of equal size. To find the perimeter, add the length and width and multiply by 2.
1. perimeter = 2(3x + 2 + 2x) = 2(5x + 2) = 10x + 4
2. perimeter = 2(4x + 1 + x) = 2(5x + 1) = 10x + 2
3. perimeter = 2(x + 5 + 7) = 2(x + 12) = 2x + 24

what is the are of triangle ABC with vertices A(-2,1),B(-2,3),C(2,1)?
Answer:
A. 4 square units
Step-by-step explanation:
The area of a triangle is given by the formula ...
A = 1/2bh
Your triangle has a base of 4 units and a height of 2 units. Its area is ...
A = 1/2(4)(2) = 4 . . . . square units
__
The triangle dimensions are easily found from your diagram by counting grid squares. If you like, you can subtract the x-coordinates of the points on the horizontal line y=1 to find the base length: 2 -(-2) = 4. And you can subtract the y-coordinates of the points on the vertical line x=-2 to find the height: 3 -1 = 2.
