Answer:

Step-by-step explanation:

You first multiply the a with bx and c then after the answer when you multiply you "add" with it would be something like

ex: 6x+4=28

- 4 -4 subtract both sides

------------------------

6x=24 then divide 6 with 24.

x= 3

A lake was stocked with 360 trout. Each year, the population decreases by 10. The population of trout in

almond37 [142]

Answer:

Part A) The y-intercept is the point (0,360) and the x-intercept is the point (36,0)

Part B) The graph in the attached figure

Part C) see the explanation

Step-by-step explanation:

Part A) Find the intercepts

Let

x ----> the number of years

f(x) ----> the population of trout in the lake

we have

$f(x)=360-10x$

This is a linear function in slope intercept form

$f(x)=mx+b$

where

m is the slope or unit rate

b is the y-intercept or initial value

In this problem we have

$m=-10\ \frac{trout}{year}$ ---> is negative because is a decreasing function

$b=360\ trouts$ ---> initial value

The y-intercept is the point (0,360)

<em>Find the x-intercept</em>

The x-intercept is the value of x when the value of f(x) is equal to zero

For f(x)=0

$0=360-10x$

Solve for x

$10x=360\\x=36$

The x-intercept is the point (36,0)

Part B) Graph the function

Plot the intercepts and join the points to graph the line

see the attached figure

Part C) Complete the interpretation of the intercepts

The x-intercept is the value of x when the value of f(x) is equal to zero

In this context, the x-intercept is the number of years, when the population of trouts is equal to zero

In 36 years, the population of trouts will be equal to zero

The y-intercept is the value of f(x) when the value of x is equal to zero

In this context, the y-intercept is the population of trouts when the number of years is equal to zero

Initially the population of trouts in the lake was 360 trouts

Match the equation with the step needed to solve it.

saveliy_v [14]

To Match

To isolate -1 we need to subtract 2m from both sides

2m - 1 = 3m (SUBTRACT 2m)

To isolate 1 we need to subtract m from both sides

2m = 1 + m (SUBTRACT m)

To isolate m we need to add 1 from both sides

m - 1 = 2 (ADD 1)

To isolate m we need to subtract 2 from both sides

2 + m = 3 (SUBTRACT 2)

To isolate m we need to add 2 from both sides

-2 + m = 1 (ADD 2)

To isolate m we need to subtract 1 from both sides

3 = 1 + m (SUBTRACT 1)

The steps needed are written in bold.

What is 18 + 46 divided by 6

Amiraneli [1.4K]

18 + 46 = 64

See image

6s into 6 = 1
6s into 4 = 0    - carry the 4 over to the next space
6s into 40 = 6 remainder 4     -   carry the 4
6s into 40 = 6 remainder 4     -   carry the 4

4 will become repeatedly carried (an infinite number of times) so we call it a recurring number. This can be shown by a number (in this case 6) with a dot above it.
(18 + 46)/6 = 10.666... or 10.67
