Explain how you can represent a proportional relationship using an equation.
The proportional relationship can be represented by using an equation y = kx
Proportional relationship defined as the relationships between two variables where their ratios are equivalent. We can say that , in a proportional relationship, one variable is always a constant value times the other. That constant is called as the "constant of proportionality"
Consider y and x are in direct proportional relationship
y ∝ x
We can write this proportional relationship as
y = kx
Where y and x are the two variables
K is the constant of proportionality
In this equation we can see that the variable y is a constant value times the other variable x
Hence, the proportional relationship can be represented by using an equation y = kx

Which equation is y = –3x2 – 12x – 2 rewritten in vertex form?
y = –3(x + 2)2 + 10
y = –3(x – 2)2 + 10
y = –3(x + 2)2 – 14
y = –3(x – 2)2 – 2
Answer:
y = -3(x + 2)^2 + 10.
Step-by-step explanation:
y = –3x2 – 12x – 2
Divide first 2 terms by -3:
y = -3(x^2 + 4x) - 2 Now complete the square on x^2 + 4x:-
y = -3(x^2 + 4x + 4 - 4) - 2
y = -3[(x + 2)^2 - 4] - 2
y = -3(x + 2)^2 + 12 - 2
y = -3(x + 2)^2 + 10.

Determine whether the table represents a linear or nonlinear function.
Answer:
Linear Function
Step-by-step explanation:
A linear function has constant slope
That means the ratio of y differences to x differences must be the same throughout the function. In other words the rate of change of the function y value is the same throughout the function
IF we look at the table we see that as x increases by 1, y decreases by 15
For example at x = 0, y = 20 and at x = 1, y = 5
So change in y/change in x = 0 = (5-20)/(1-0) = -15/1 = -15
If we look at another pair of points, say x = 1, y=5 and x = 2, y = -10
we get the rate of change = (-10 - 5)/(2-1) = -15/1 = -15
This is the same for any two x, y pair of values
So it is a linear function
The Marianas Trench in the Pacific Ocean is the deepest part of the ocean. It's depth is 6.85 miles. Sound
travels 4700 feet in one second under water. Find the time, to the nearest tenth of a second, it takes sound to
travel from the surface of the ocean to the bottom of the Marianas Trench and back.
6.85 miles is how deep it is. Under water, sound may travel 4700 feet in a second. The Time takes to travel the sound is 7.69.
Given that,
The deepest area in the ocean is the Marianas Trench in the Pacific Ocean. 6.85 miles is how deep it is. Under water, sound may travel 4700 feet in a second.
We have to calculate the time it takes for sound to travel from the ocean's surface to the Marianas Trench's depths and back, to the nearest tenth of a second.
We know the Distance formula is
Distance =rate×times
Time=Distance/rate
We convert 4700 feet to miles
We get,
4700 feet =0.89 miles
Now,
Time=6.85/0.89
Time=7.69
Therefore, the Time takes to travel the sound is 7.69.

driveways did you shovel?
1800 lawns were mowed. 800 driveways were shoveled.
What is equation?A formula that expresses the connection between two expressions on each side of a sign. Typically, it has a single variable and an equal sign. Like this: 2x - 4 Equals 2. In the above example, the variable x exists. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.
Given Data
Let mowed grass be x
Let shoveled snow be y
Last year you mowed grass and shoveled snow for 12 houses
x + y = 12
y = 12 -x
You earned $225 for each lawn you mowed and $200 for each house you shoveled for a total of $2600.
225x + 200y = 2600
Equating value of y
225x + 200(12-x) = 2600
225x + 2400 - 200x = 2600
225x - 200x = 2600 - 2400
25x = 200
x = 8
For value of y,
y= 12 -x
y = 12 - 8
y = 4
Lawn mowed = 225(8)
Lawn mowed = 1800
Shoveled snow = 200(4)
Shoveled snow = 800
1800 lawns were mowed. 800 driveways were shoveled.

rectangle QRST has coordinates Q(-8,5), R(-8,7), S(-5,7), and T(-5,5). dilate the rectangle by a scale factor of 4 with a center of dilation at the origin. write a rule to describe this transformation and use the rule to determine the coordinates of rectangle Q'R'S'T'
The rule to describe the transformation, dilation by a scale factor of 4 with center of dilation at the origin is (x,y)→(4x,4y) and the coordinates of rectangle Q'R'S'T' is are Q'(-32,20) , R'(-32,28) , S'(-20,28) , T'(-20,20) .
In the question ,
a rectangle QRST with coordinates Q(-8,5), R(-8,7), S(-5,7), and T(-5,5) is given ,
and to dilate the rectangle by a scale factor of 4 with center of dilation at the origin , we multiply coordinates of the original shape with the dilation factor
so the rule to describe the dilation will be
(x,y)→(4x,4y)
Using this rule to find the new coordinates of the rectangle Q'R'S'T' .
When Q = (-8,5)
Q' = (4*(-8),4*5)
Q' = (-32,20)
When R = (-8,7)
R' = (4*(-8),4*7)
R' = (-32,28)
When S = (-5,7)
S' = (4*(-5),4*7)
S' = (-20,28)
When T= (-5,5)
T' = (4*(-5),4*5)
T' = (-20,20)
So the coordinates of the rectangle Q'R'S'T' is Q' = (-32,20) , R' = (-32,28) , S' = (-20,28) , T' = (-20,20) .
Therefore , the rule to describe the transformation, dilation by a sale factor of 4 with center of dilation at the origin is (x,y)→(4x,4y) and the coordinates of rectangle Q'R'S'T' are Q'(-32,20) , R'(-32,28) , S'(-20,28) , T'(-20,20) .

you repeatedly roll a fair six-sided die until you roll a 1 (and then you stop). every time you roll a 3, you win a points, and every time you roll a 6, you lose b points. you do not win or lose any points if you roll a 2, 4 or a 5. what is the expected number of points (as a function of a and b) you will have when you stop?
The expected number of points as a function of a and b is C = b+a.
In this questions what we are been asked is for the expected value C, to solve the problem we need to recognize the random variables and their respective probability.
x1 = roll a 1 -> P1 = 1/6
x2 = roll a 2 -> P2 = 1/6
x3 = roll a 6 -> P3 = 1/6
x4 = roll a 1, 4 or 5 -> P4 = 1/2
E = P1*x1 + P2*x2 + P3*x2 + P4*x4
x1 is equal to zero (no points and the game stop), x2 is equal to C+b (win a points, affecting the expected value), x3 is equal to C-a (win b points, affecting the expected value) and x4 is equal B (no points are lost and the game continues, therefore the expected value is not affected)
C = 1/6*0 + 1/6*(C+b) + 1/6*(C-a) + 1/2*(C)
1/6*C = 1/6*b + 1/6a
Solving for C
C = b+a
Conclusion: If you get a "2, 4 or 5, this means the game will be unaffected (in terms of points), you need to pay special attention to x1 and x2 (all with the same probability) that are the results that are going to affect your game.

Write a directed number suggested by the following :
A 14 degrees below zero
B altitude 200 metres
The directed number suggested by the following will be:
A 14 degrees below zero = -14°
B altitude 200 metres = +200
How to illustrate the information?It should be noted that the directed number simply means the numbers that had both size and direction. It should be noted that the direction can either be positive or negative.
A measurement of altitude or height is the distance between a location or item and a reference datum, typically in the vertical or "up" direction. Although the term "altitude" is frequently used to refer to a location's height above sea level, the term "elevation" is frequently preferred in the context of geography. The term "depth" often refers to vertical distance measurements taken in the "down" direction. Globally, the research team discovered that the pace of temperature change frequently quickens as altitude increases.
Therefore, the directed number suggested by 14 degrees below zero will be negative 14 and this will be -14°
Also, altitude 200 metres will be positive 200 and this will be +200

Answer: The answer is C. You start off by first thinking about your slope equation, being y=Mx+b. Remember b equals your y- intercept. In this case one of your y-intercepts is positive 1 and the other is positive 2. Now you have the “b” part of the equation. Looking for slope or your “mx” part of the equation is next. All this is going to be is the rise over the run from your y intercept. How much did you rise and how much did you run to get to the next point. Both of these slopes are going up therefore both slopes will be positives. For the first one it rises 2 and runs 1 to get to the next point, however you do not need to write the one at the bottom of the 2 and can leave it as “2x+1”, because it is shaded below the red line the inequality will be less than or equal to

What is a linear function?A linear function is modeled by:
y = mx + b, In which: m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.
b is the y-intercept, which is the value of y when x = 0, and can also be interpreted as the initial value of the function.
here, we have,
The lower bound of the interval is a linear function with
y-intercept of b = 2,
that also passes through (2,3), hence the slope is:
m = (3 - 2)/(2 - 0)
= 1/2.
Hence the inequality is:
y ≥ x/2 + 2
The upper bound of the interval is a linear function with y-intercept of b = 1, that also passes through (2,5), hence the slope is:
m = (5 - 1)/(2 - 0) = 2.
Hence the inequality is:
y ≤ 2x + 1

Solve for x (6x+5) 86
Answer:
x = -5/6
Step-by-step explanation:
First, set the equation (6x + 5) * 86 equal to 0. The equation is now (6x + 5) * 86 = 0. Next, simplify (6x + 5) * 86 by multplying 86 to 6x and 5. This will turn the equation into 516x + 430 = 0. Next, subtract 430 from both sides, cancelling out the 430 on the left side. After that, get the x value by itself by dividing 516 on both sides, cancelling out the 516 on the left side. Now, x = -430/516. From here, find the common factor of both the numerator and denominator; this turns out to be 86. Since 86 is the common factor, divide the numerator and denominator by 86 and you get x = -5/6.
