Answer:
3a-3b-5c
Step-by-step explanation:
((3a-3b)²-(5c)²)÷(3a-3b+5c)=((3a-3b-5c)(3a-3b+5c))÷(3a-3b+5c)=3a-3b-5c
They are inverses.
The easiest way to solve this is to take the g(x) equation and switch the g(x) with the x. Then solve for your new g(x). Since it looks just like f(x) after doing that, it is an inverse.
Answer:
-68.3012701892
Step-by-step explanation:
I put it in calculaotor
<h3>The solution is (x, y) = (-2, 3)</h3>
<em><u>Solution:</u></em>
<em><u>Given system of equations are:</u></em>
4x + 5y = 7 ------ eqn 1
3x -2y = -12 ------- eqn 2
Multiply eqn 1 by 2
8x + 10y = 14 ------ eqn 3
Multiply eqn 2 by 5
15x - 10y = -60 ------- eqn 4
Add eqn 3 and eqn 4
8x + 10y = 14
15x - 10y = -60
( + ) -------------
23x = -46
<h3>x = -2</h3>
Substitute x = -2 in eqn 1
4(-2) + 5y = 7
-8 + 5y = 7
5y = 15
<h3>y = 3</h3>
Thus the solution is (x, y) = (-2, 3)
