G(x)=-2/5x-2 inverse function with steps please​
podryga [215]

Answer:

{g}^{ - 1} (x) =  -  \frac{5}{2} x  -  5

Step-by-step explanation:

We want to find the inverse of

g(x) =  -  \frac{2}{5}x - 2

Let

y=  -  \frac{2}{5}x - 2

We interchange x and y to get:

x=  -  \frac{2}{5}y - 2

We now solve for y to obtain:

x + 2=-\frac{2}{5}y

5x =  - 2y - 10

Add 10 to both sides to get:

5x + 10 =  - 2y

Divide through by -2

y =  -  \frac{5}{2} x  -  5

Therefore

{g}^{ - 1} (x) =  -  \frac{5}{2} x  -  5

Write a system of equations with a solution (4,–3)
Gennadij [26K]
<span>1.       </span><span>So we have the system of equation. (4, -3)
let’s create another system of equation.
Let a = 4
and Let b = -3
First equation
=> Let’s pick any numbers to be used. Let’s have number 5
=> 5a + 5b
=> 5 (4) + 5 (-3)
=> 20 + (-15)
negative and positive is equals to negative
=> 20 – 15
=> 5 (this the first value of our equation, let this be the value of X)

Second
=> Pick another number, Let’s have 6
=> 6a + 6b
=> 6 (4) + 6 (-3)
=> 24 + (-18)
=> 24 – 18
=> 6 (this is the value of our second equation, let this value be Y)

Now, we have (A, B) = (4, -3) and (X, Y) = (5,6)</span>

1. 3x + 6y = 3 and 7x + 3y = 7<br>ons for bo​
sweet-ann [11.9K]

Answer:

(1,0)

Step-by-step explanation:

3x + 6y = 3

7x + 3y = 7

Multiply the second equation by -2

-2( 7x + 3y = 7)

-14x -6y = -14

Add this to the first equation to eliminate y

3x + 6y = 3

-14x -6y = -14

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

-11 x = -11

Divide by -11

x = 1

Now find y

3x + 6y = 3

3 +6y = 3

Subtract 3 from each side

6y = 0

y =0
