Which three (3) characteristics are found in ALL proportional equations.

Answers

Answer: A,  C   and  E

Step-by-step explanation:

All proportional equations or lines always go through the origin because when it's x coordinate is 0, it's y coordinate has to be 0 too.

It is also a straight line  .

And k will always be the constant value, as if    y = kx.  K is the constant change or the slope.

A)starts the origin
C) a straight line
E)contains the point (1,k) where k is the constant

Isaac conducted a scientific experiment. For a certain time, the temperature of a compound rose 3 3/4 degrees every 3/4 of an hour. What was the rate, in degrees per hour, that the temperature of the compound rose?

Answers

Answer: it should be 5

Step-by-step explanation: if 3 3/4 divided into three parts its 1 1/4. If we add 3 3/4 and 1 1/4, then we have 5

The rate of rise in temperature in degrees per hour will be equal to 5° per hour.

What is an arithmetic operation?

The four basic mathematical operations are the addition, subtraction, multiplication, and division of two or even more integers.

Among them is the examination of integers, particularly the order of actions, which is crucial for all other mathematical topics, including algebra, data organization, and geometry.

As per the given information in the question,

The temperature rise of the compound to 3 3/4° every 3/4 of an hour.

1 hour = 60 minutes then,

3/4 of an hour = 3/4 × 60 = 45 minutes.

(15/4)° rise in 45 minutes or,

3.75° rise in 45 minutes.

Let the rise in temperature in 1 hour will be x° then,

x = (3.75 × 60)/45

x = 5° per hour.

A point has the coordinates (0, k).

Which reflection of the point will produce an image at the same coordinates, (0, k)?

a reflection of the point across the x-axis
a reflection of the point across the y-axis
a reflection of the point across the line y = x
a reflection of the point across the line y = –x

Answers

Using reflection concepts, it is found that the correct option is:

a reflection of the point across the y-axis

---------------

The rule for a reflection of a point across the x-axis is: [tex](x,y) \rightarrow (x,-y)[/tex], thus [tex](0,k) \rightarrow (0,-k)[/tex]The rule for a reflection of a point across the y-axis is: [tex](x,y) \rightarrow (-x,y)[/tex], thus [tex](0,k) \rightarrow (-0,k) = (0,k)[/tex]. This is the correct option.The rule for a reflection of a point across the line y = x is: [tex](x,y) \rightarrow (y,x)[/tex], and thus, [tex](0,k) \rightarrow (k,0)[/tex].The rule for a reflection of a point across the line y = -x is: [tex](x,y) \rightarrow (-y,x)[/tex], and thus, [tex](0,k) \rightarrow (-k,0)[/tex].

Answers

Answer:

-9x+5y=-4

Step-by-step explanation:

Answer:

m= 9/5

Step-by-step explanation:

Parallel lines have the same slope.

So if you can find the slope of the given line, you have the slope you want.

Change the line into the form

y=mx + c

The value of m

will be the slope of the line.

9x −4 = 5y ← to make the y term positive

y=9/5x − 4/5

m=9/5

The parking would be $4 while the hourly rent for a paddle boat is $14 because as the hours increase the cost increases by $14 so that would be the rent and to find the parking you would subtract $14 from the cost of an hour rent and it would give you the cost for parking I hope that made sense
