Answer:
y>-5-3x
Step-by-step explanation:
The value of x, y and z from the system of equation are -1, -8 and 5 respectively.
Data;
- -2x + 6y + 3z = -31
- -3y + 7z = 59
- 2z = 10
<h3>System of Equation</h3>
To solve this problem, we have to solve the system of equation using substitution method.
From equation (iii)

let us substitute the value of z into equation (ii)

Let's substitute the value of x and y into equation (i)

From the calculation above, the value of x, y and z are -1, -8 and 5 respectively.

Answer
idk maybe 5 is the flvs?
Step-by-step explanation:
Step-by-step explanation:
Given
f(x) = 2x - 10
f^-1(x) = ?
Now
Let y = f(x)
y = 2x - 10
Interchanging the roles of x and y we get,
x = 2y - 10
x + 10 = 2y
y =(x + 10) / 2
f^-1(x) = (x + 10)/ 2
Hope it will help :)❤
