6x + 5y = 147<br> 8x + 4y = 156
satela [25.4K]

Answer:

[12, 15]

Step-by-step explanation:

{6x + 5y = 147

{8x + 4y = 156

-¾[8x + 4y = 156]

{6x + 5y = 147

{-6x - 3y = -117 ← New Equation

________________

2y = 30

___ ___

2 2

y = 15 [Plug this back into both equations to get the x-coordinate of 12]; 12 = x

So, using the Elimination Method, what I did here was took the bottom equation and multiplied it by -¾, turning 8x to -6x, canceling out all <em>x-terms</em><em>.</em><em> </em>It does not matter which variable you choose to eliminate, as long as you know what you are doing.

I am joyous to assist you anytime.

Which represents the inverse of the function f(x) = 4x?
Sidana [21]

Answer:

h(x) = x/4

Step-by-step explanation:

To find the inverse of a function, exchange x and y and then solve for y

y = 4x

Exchange x and y

x = 4y

Solve for y

Divide each side by 4

x/4 = 4y/4

y = x/4

The inverse  is

h(x) = x/4
