Answer:

y = 2x + 5

Step-by-step explanation:

y = mx + b    :    Slope Intercept Form

Our m (slope) does not change, but our b (y-intercept) does.


Step 1: Plug in all numbers except b

y = 2x + b

3 = 2(-1) + b

Solve

5 = b


Step 2: Add slope and intercept into equation

y = 2x + 5

So can anyone help me with #1 and 2 and show work I have no idea what I’m doing
Neporo4naja [7]

Answer:

1.

x = 44*2

<h2>x = 88</h2>

2.

x = 62*2

<h2>x = 124</h2>

3.

x = 108/2

<h2>x = 54</h2>

4.

x = 160/2

<h2>x = 80</h2>

5.

12x = 60*2

12x = 120

x = 120/12

<h2>x = 10</h2>

6.

5x = 50/2

5x = 25

x = 25/5

<h2>x = 5</h2>

A population of fish in a lake is 14000 in 2010. The population decreases 6% annually. What is the population in 2019
kodGreya [7K]

Answer:

8022.

Step-by-step explanation:

Let x be the number of years after 2010.

We have been given a population of fish in a lake is 14000 in 2010. The population decreases 6% annually.

We can see that population of fish is the lake is decreasing exponentially as it is decreasing 6% annually.

Since we know that an exponential function is in form: y=a*b^x, where,

a = Initial value,

b = For decrease or decay b is in form (1-r) where r represents decay rate in decimal form.

Let us convert our given decay rate in decimal form.

6\5=\frac{6}{100}=0.06

Upon substituting our given values in exponential form of function we will get the population of fish in the lake after x years as:

y=14,000*(1-0.06)^x

y=14,000*(0.94)^x

Let us find x by subtracting 2010 from 2019.

x=2019-2010=9

Upon substituting x=9 in our function we will get,

y=14,000*(0.94)^9

y=14,000*0.5729948022286167

y=8021.927\approx 8022

Therefore, the population of fish in 2019 will be 8022.
