The rule for the relationship between the nonfiction and fiction books as an expression is n = 4f.

We have,

Let's write a rule for the relationship between the number of non-fiction books (n) and the number of fiction books (f) based on the given information.

We are told that the library loans 4 times as many non-fiction books as it does fiction books.

This means that the number of non-fiction books (n) is equal to 4 times the number of fiction books (f).

Mathematically, we can express this relationship as:

n = 4f

Where:

n = Number of non-fiction books

f = Number of fiction books

Thus,

The rule for the relationship between the nonfiction and fiction books as an expression is n = 4f.

Answer:

y = (-3/4)x - 1/4

Step-by-step explanation:

Use the slope-intercept formula y = mx + b.  Here m = -3/4 and b = -1/4, and so:  y = (-3/4)x - 1/4

The equation of the line with slope  -3/4 and y-intercept is -1/4 is y=-3/4x-1/4.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of the line is the ratio of the rise to the run, or rise divided by the run.

It describes the steepness of line in the coordinate plane.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

Given that the slope is -3/4 and y-intercept is -1/4.

We have to find the equation of line with slope -3/4 and y-intercept is -1/4.

m=-3/4 and b = -1/4

Now plug in these values in slope intercept form y=mx+b

y=-3/4x-1/4

Hence, y=-3/4x-1/4 is the equation of the line with slope  -3/4 and y-intercept is -1/4.

can you pls make me BRAINLYS

Answer:

A

Step-by-step explanation:

Looking at the number line, you will notice that A, B, and C are less than 0.

Eliminate D, which is greater than 0.

Further still, as negative numbers get 'smaller', they go from -1 to -∞.

i.e.: -1 > -2 > -3

if you forget the above fact, looking at the number line, you can see that A is between -1 and -2, and [tex]-1\frac{5}{8}[/tex] is between -1 and -2 just as [tex]1\frac{5}{8}[/tex] is between 1 and 2.

Then, simply counting the ticks from -1 to -2, you can see that A falls on the 5th tick, while -2 falls on the 8th tick from -1.

Answer: Not what's written down.

Step-by-step explanation:

Okay, so basically, if you have a letter, no other number can go with that number with a letter. So like 5x + 2b -7.

There is only one number that has x, so 5x.

Same with b. 5x + 2b.

Now, there is no letter with the 7, so that will stay the same.

So, the answer is 5x + 2b -7.

Now, I look at your question.

If I do all of the work I just showed, the answer is C.

The two other numbers could be 0.83.

First, do the equation 2 - 0.34 = 1.66.

Next, divide 1.66 ÷ 2 = 0.83.

Finally, add 0.83 + 0.83 + 0.34 = 2.

So the two other decimals Holland could do is 0.83.

Answer: 20c + 10.

Step-by-step explanation:

(c represents crates)

I wrote each equation separately first.

Supplier A: 4c + 6

Supplier B: 6c - 1

Supplier C: 10c + 5

We can add all the cs from each supplier giving us 4c + 6c + 10c which equals 20c. Now we can add the extra shoes as, 6 + (-1) + 5 equaling 10. I wrote -1 because we are missing that shoe, but you can write it as 6 - 1 + 5 instead. Together the two numbers make the equation 20c + 10. Hope that helps : )

Answer:

67 inches : 360 inches

Step-by-step explanation:

30 feet = 360 inches

Martin Luther King Jr : Statue

                              67 : 360

The ratio of Martin Luther King Jr's actual height to the statue is 67 : 360.

The ratio shows how many times one value is contained in another value.

Example:

There are 3 apples and 2 oranges in a basket.

The ratio of apples to oranges is 3:2 or 3/2.

We have,

Martin Luther King Jr height = 5 feet tall and 7 inches

This is 67 inches tall.

The statue height = 30 feet tall.

This is 12 x 30 = 360 inches

Now,

The ratio of Martin Luther King Jr's actual height to the statue.

= 67 : 360

Thus,

The ratio is 67 : 360.

Answer:

Step-by-step explanation: 12X2=24 pizza pieces on the two plates in all.

Answer: 5 length & width

Step-by-step explanation:

Since this is a square all sides would be the same length & width which would be 5 because each side is symmetric. So if you do 5 times as many sides as there is (5 x 4) it would give you 20

So the LENGTH of EACH side is 5 and the AREA in total or PREMIETER would be 20 all together.
