Answer:

425

Step-by-step explanation:

Let the original population of blackbirds be x.

<u>Original population</u>              <u>decreases by</u>                   <u>New population</u>

          100                                     24                                       76

            x                                        24                                     323

<u>Now we can make an expression like this.</u>

100  ⇒  76

x     ⇒   323

And now let us use cross multiplication and solve for x.

<u>Let us solve it now.</u>

323 × 100 = 76x

32300 = 76x

<u>425</u>=  x

Why equation is represented by the equation on the graph
Nina [5.8K]

Answer: Option D

Step-by-step explanation:

The equation of the line, by definition, has the following form:

y=mx+b

Where m is the slope and b  is the y-intercept

As you can see in the graph, the line intercept the y-axis at 2, therefore b=2.

Now, to find the slope, choose any point of the line and solve for m:

Point (1,1)

1=m(1)+2

-1=m

Then, the equation is:

y=-x+2

Stolb23 [73]

Answer:

C

15 + x

Step by step explanation

For Company X, the initial cost is 30 cents  plus 5 cents per minute, so the expression would be 30 + 5x (x would represent minutes.

For Company Y, the initial cost is 15 cents  plus 4 cents per minute, so the expression would be 15 + 4x (x would represent minutes.)

Then subtract the expression of Y from the expression of X to show the difference in value between Y and X.

So, 30 + 5x - (15 +4x)

Distribute the subtraction sign.

30 + 5x - 15 - 4x

Solve across.

15 + x
