The rate of change is
(2- (-1))/ (3/2-(-4)) => 3 / (11/2)
that is equal to 6/11 so almost 1/2

Help!<br> Which answer is correct?

Luda [366]

Well, since the graph starts at (0,50), making our y-intercept 50, we can knock off D as an option.

The next step is to find the slope. To do this, find two points and subtract the y values over the x values. (Just make sure that whichever y value you start with - start with the same x value).

So we have >>> (50, 200) and (0,50) from earlier.

200 - 50 / 50 - 0 = 150/50 or 3/1, or 3.

This makes the correct answer A since the equation is represented as y = mx + b, where m is the slope and m has a value of 3.

Rational number between -1 and 1<br>

Nonamiya [84]

Answer:

$\dfrac{-1}{2}$

Step-by-step explanation:

We need to find ration numbers between -1 and 1.

Multiplying and dividing both -1 and 1 by 2.

$\dfrac{-1\times 2}{2}=\dfrac{-2}{2}$

and $\dfrac{1\times 2}{2}=\dfrac{2}{2}$

Now, the rational number between -2/2 and 2/2 is $\dfrac{-1}{2}$ .

Answer: Team one = 1/5

Team 2 = 4/21

Team A is the fastest

Step-by-step explanation: Answer: Team one = 1/5

Team 2 = 4/21

Team A is the fastest

Step-by-step explanation: TEAM A

Tammy working alone in 1hr can clean 1/2

Melissa working alone in 1 hr can clean 1/3

working together in 1hr ,let x represent the area they will clean we have

$\frac{1}{1/2}$ + $\frac{1}{1/3}$ = 1/x

⇒ 3 + 2 = 1/x

5 = 1/x

x = 1/5

TEAM B

Santay working alone can clean 1/4

Leticia working alone in 1 hr can clean 4/5

working together in 1 hr ,let y represent the amount they clean, we have

$\frac{1}{1/4}$ + $\frac{1}{4/5}$ = 1/y

4 + 5/4 = 1/y

21/4 = 1/y

y = 4 /21

comparing x and y , 1/5 is greater than 4/21 , therefore Team A is faster
