Answer: y = - 0.4 x - 4.5

Step-by-step explanation:

Equation y=mx+b

m is the slope

x is *ANY* x coordinate

y is *ANY* y coordinate

b is y intercept or WHERE the point is on the Y AXIS

Lets look at the given:

Slope (m) is -2/5

Passes through point 15, -9/2

As you can see, the point goes through the Y axis at (-9/2)

Our equation is y = - 0.4 x - 4.5

It takes 24 megabytes to store 144 songs on a music player. What is the greatest number of songs that 60 megabytes could store?
givi [52]

Option B

We can store a total of 360 songs in 60 megabytes of space.

<u>Solution:</u>

It is given to us that It takes 24 megabytes to store 144 songs on a music player. We have been asked to find out what is the greatest number of songs that 60 megabytes could store.

To solve this question we can use the unitary method.  

We will first find out how many songs can be stored in 1 megabyte. This can be done as follows:

=\frac{144}{24}=6

Therefore, we can store 6 songs in 1 megabyte.

So, in 60 megabyte we can store the following number of songs:

=60 \times 6=360

So, we can store a total of 360 songs in 60 megabytes.

F(x) shows number of bees and g(x) shows number of flowers
f(x)=1500*(0.88)^n
g(x)=800-25n
n shows month
B)n=6
1500*(0.88)^6=696
800-25*6=800-150=650
c)it's hard to say because you should find n in this equation
1500*(0.88)^n=800-25n
but it seem n is between 6 and 7
