The answer is B) -x^2-3
This is because you have an exponential graph that is flipped, hence the negative sign, and down 3.

Write in equation of the line in the graph
salantis [7]
To write the equation of a line, we use the equation: y = mx +b.

m is the slope of the line, which can be calculated using the equation:
m = (y2 - y1)/(x2 - x1) 
We can choose any two points on the line to put into this equation. The red dots are at (0,0) and (-6,-2), so we will use those, but you would get the same answer by using any other pair of coordinates on the blue line.
m = (-2 - 0)/(-6 - 0) = 2/6 = 1/3

b is the y-intercept of the line. The y-intercept is the y-coordinate when the line crosses the y-axis. It crosses the y-axis at (0,0), so the y-intercept is 0.


Now, we plug our values back into the full equation to get the equation of the line.
y = mx + b
y = (1/3)x + 0 

So the final answer is y = (1/3)x or y = x/3, depending on how you want to write it.

Witch one is bigger 3/5, 1/2, or 99/100
Solnce55 [7]
We need to make them all equivalent, so when all denominators are equal, we can see. 1/2 is 50/100, 3/5 is 60/100, and 99/100 stays the same.
The biggest is 99/100.

12.<br>The container shown has a capacity of 60 milliliters.<br>What fraction of it is empty?<br>​
White raven [17]

This is an incomplete question, the image is shown below.

Answer : The fraction empty container is, \frac{7}{12}

Step-by-step explanation :

As we are given that:

The capacity of container = 60 mL

In the given figure, the container is filled with 25 mL.

That means,

60 - 25 = 35 mL container is empty.

Now we have to calculate the fraction of it is empty.

The fraction of it is empty = \frac{\text{Capacity of empty container}}{\text{Total capacity of container}}

The fraction of it is empty = \frac{35mL}{60mL}

The fraction of it is empty = \frac{7}{12}

Therefore, the fraction empty container is, \frac{7}{12}

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

-  \frac{2}{3}  - ( -  \frac{4}{6} ) =  \\

-  \frac{2}{3}  +  \frac{4}{6}  =  \\

-  \frac{2}{3}  +  \frac{2 \times 2}{2 \times 3}  =  \\

-  \frac{2}{3}   +  \frac{2}{3}  =  0\\

Lydia spent 4/5 of her money on a mobile phone and 2/3 of the remaining amount on a bag. She had $60 left. How much more money d
KengaRu [80]
The answer is 600 because 1 out 3 is 60 so to find the bag multiply by two while to find 1 out 5 of her monet take 60 times 3 which is 180. 180 times 4 is the money she spent on her mobile phone so take the money spent on her mobile phone(720)minus the amount of money spent on the bag(120)
