To find the value of y, we must substitute x with 10 in the equation.
5x - y = 54
5(10) - y = 54

Simplify
50 - y = 54

Move 50 to the right side. After moving to other side, it becomes negative.
50 - y = 54
- y = 54 - 50
- y = 4
----------------------- divide both side by -1
y = -4

The value of y is -4

A deer population is declining by 2.2% per year. The population can be modelled using the formula p = 240(0.978)n , where P is t

ale4655 [162]

Answer:

The current deer population is 240.

Step-by-step explanation:

The expression given models a exponential decay follows:

$p(n) = 240*(0.978)^n$

For every year that passes since the beginning of the count the population is 0.978 of the year prior. Assuming that the count starts at this year, then "n" is equal to 0, applying this value of n to the formula gives us:

$p(0) = 240*(0.978)^0\\p(0) = 240*1 = 240$

The current deer population is 240.

Which statement compares the two numbers correctly?

Pie

Hey there! We are given two decimal numbers to compare.

52.311 and 52.31

These two numbers are similar except that 52.311 has another 1 in while 51.31 doesn't.

Keep in mind that 52.31 can also refer to 52.310

So we are comparing 52.311 and 52.310

Since 1 is greater than 0.

52.311 is greater than 52.31 (52.311 > 52.31)

Let me know if you have any questions!
