You can use substitution or elimination or graphing to solve the equation. Since both of the equations are in slope intercept form it will be easier to use substitution or to graph it and find the point of interception.

You can write (6x=10)=(-4x-20), because both expressions are equal to the same thing, so they're equal to each other. From that, you easily solve for 'x', and then write that number back into one of the original equations to find 'y' .

find five solutions of the equation y=20x. select integers for values for x starting with -2 and ending with 2

Nataly_w [17]

Answer:

-440, -4440, -44440, -444440, -4444440

Step-by-step explanation:

First, let's find values for x which start is a -2 and end with a 2.

-22

-222

-2222

-22222

-222222

Now we can find the y value by multiplying each term by 20.

-22 --> -440

-222 --> -4440

-2222 --> -44440

-22222 --> -444440

-222222 --> -4444440

What is the percent of change from 4,000 to 600?<br> work too plz

xenn [34]

$\frac { n }{ 100 } \cdot 4,000=600\\ \\ 4,000\cdot n=60,000\\ \\ Therefore:\\ \\ n=\frac { 60,000 }{ 4,000 }$

$\\ \\ =\frac { 60\cdot 1,000 }{ 4\cdot 1,000 } \\ \\ =\frac { 60 }{ 4 } \\ \\ =15$

As 15% of 4,000 is 600, the percentage change was -85%.

What are the domain and range of the exponential function below?

Hunter-Best [27]

The domain and the range of the function are all set of real numbers

<h3>How to determine the domain and the range?</h3>

The function is given as:

f(x) = 4x + 3

The above function is a linear function

Linear functions have a domain and a range of all set of real numbers

Hence, the domain and the range of the function are all set of real numbers
