Look at the number line, 0 going to the left is neg going to the right is positive. Look at 1 on the left, go to the other side and look at the 1 again but with a - in front of it. The next one is -2. The one next to -2 is -3 and -4 is next to it. I hope this will help you out.

I have attached a picture of the number line.

a. Remember that to the right is positive and to the left is negative
b. Remember that neg time neg is positive
c. There is no such thing as a neg 0. It's just 0.

Hope this helps,

pychu [463]

To find the y int, sub in 0 for x and solve for y

2x + y = 4
2(0) + y = 4
y = 4......so ur y int is (0,4)

100m In 9 3/5 seconds

Nostrana [21]

Answer:

Speed = 10.42 m/secs

Step-by-step explanation:

We have been given with:-

Distance = 100m

Time taken = 9 $\frac{3}{5}$ secs

1) First, we need to convert the mixed number 9 $\frac{3}{5}$ to an improper fraction.

<u>Method to convert a mixed number to an improper fraction</u>

<u> $a\frac{b}{c} = \frac{c*a+b}{c}$ </u>

Applying the above formula, we get

9 $\frac{3}{5}$ = $\frac{5*9+3}{5}$

= $\frac{45+3}{5}$

= $\frac{48}{5}$

2) Now we need to convert $\frac{48}{5}$ into a decimal by dividing 48 by 5.

We get time taken as 9.6 secs

3) We need to find the speed using the below formula:-

Speed = $\frac{Distance}{Time taken}$

Plugging the values of Distance and Time taken into the formula, we get

Speed = $\frac{100}{9.6}$

= 10.416 m/secs

4) Upon rounding it to the nearest hundredth, we get

Speed = 10.42 m/secs

And animals weight change from 12 pounds to 16 pounds what was the percent increase to the nearest whole number

amm1812

That's a 33% increase.

I calculated this using the formula:

$\frac{|n-o|}{o} * 100$

Where n = the new value (16 in your question), o = the old value (12 in your question) and the result is outputted as a percent increase. You can check that this is correct by finding 33% of 12, adding the result to 12, and checking that the result equals your "new" number.

Note that 33% is only an approximation as your question requires a number rounded to the nearest whole.

Determine the values of n

N76 [4]

<h2>Answer:</h2><h3>b. n is odd</h3><h2>Step-by-step explanation:</h2>

In this problem, we assume that $n$ is a whole number. The definition of inverse functions tells us that a function $f$ has an inverse function if and only if the function is one-to-one, that is, if there is no any horizontal line intersecting the graph of $f$ at more than one point. This only happens if $n$ is odd. This is called the Horizontal Line Test for Inverse Functions. So let's take two examples:
