-9x = 5 - 2y. 15x = -11 + 2y HELP ​

Mathematics
1 answer:
I am Lyosha [343]4 years ago
6 0

Answer:

(-1, -2)

Step-by-step explanation:

-9x= 5 - 2y

15x = -11 + 2y => 2y = -11 - 15x

Plug the value for 2y into the first equation.

-9x = 5 - 15x - 11. Solve for x.

-9x = -6 - 15x.

-9x + 15x = -6.

6x = -6.

x = -1.

Now that we found x, we will solve for y.

2y = -11 - 15(-1)

2y = -11 + 15

2y = -4

y = -2.

Thus, our solution set is (-1, -2).

Hope this helps!

G(x)=15x-10 inverse function with steps please​
Alexus [3.1K]

Answer:

The inverse function is g(x) = 

\frac{x + 10}{15}

Step-by-step explanation:

You can find the inverse of any function by switching the g(x) value (or whatever the function value is labelled) and the x value. Then solve for the new g(x) value. The result will be your inverse function.

g(x) = 15x - 10 ---> Switch the g(x) and x

x = 15g(x) - 10 ---> Add 10 to both sides

x + 10 = 15g(x) ----> Divide both sides by 15.

\frac{x + 10}{15} = g(x) ----> Switch the order

= g(x) ----> Switch the order

g(x) =

\frac{x + 10}{15}

And that would be your inverse function.
