Answer:

The y= -28x+4 function is changing more quickly because the -28 of x is the bigger number meaning it is the bigger slope.

Step-by-step explanation:

hopefully that helps, if not let me know of the option you have that I can select from to fully answer the question.

How is twelve divided by fifteen equal to eight.
alexira [117]
It isn't at all!

When dividing numbers, the easiest way is to imagine the values as a fraction, and then reduce that fraction. If it reduces to a core fraction (ones that you should know their decimal value without thinking), then you have your answer.

\frac{12}{15} =  \frac{4}{5} = 0.8

We simplified our fraction by dividing the numerator and denominator by 4, which left us with  \frac{4}{5}, which we know is equal to 0.8.

You may be confused thinking that 0.8 is the same as 8. 0.8 is actually a tenth of the value of 8. This makes them very different values.

Below, I have also included a picture to help you memorize your common/core fractions. I recommend learning these as they will help you get through all sorts of math, from Geometry to Calculus!

A puppy and a kitten are 180 meters apart when they see each other. The puppy can run at a speed of 25 m/sec, while the kitten c
Lelechka [254]
Make two equations representing the position of each animal, p and k, for the puppy and kitten respectively.

p=25t and k=180+20t  

The puppy will catch the kitten when p=k so we can say:

25t=180+20t  subtract 20t from both sides

5t=180  divide both sides by 5

t=36

So the puppy will catch the kitten after 36 seconds.

7 times what equals 1?
Arturiano [62]
For this case, the first thing we must do is define a variable.
 We have then:
 x: unknown number
 Doing the multiplication we have:
 (7) (x) = 1

 From here, we clear the value of x.
 We have then:
 x =  \frac{1}{7} 

 Therefore, we have:
 (7) ( \frac{1}{7} ) = 1

 Answer:
 
7 times 1/7 equals 1

fredd [130]

Answer:

Hi!

First you would start at -4 on the x-axis, then you would move up 3 spaces and put your point there.

The x-axis is the horizontal line, and the y-axis is the vertical line.

I hope this helps you!
