Please don't get mad at me but I did this on tn ready the other day and we learned about it but what you would do is multiply 8x9 then subtract 7 from the product and add 4 to the answer you got and then multiply it by that answer by 5 and you should get your answer. I hope I helped you?

You find the answer by first multiplying 8x9=72 then 4x5=20 and then 72-9=63 and then 63+4=67 your final answer should be 87

Levant will receive about 9 american dollars when he exchanges his pesos.

Find an equation for the inverse of the relation y=6x-3. Show how you found the inverse equation.

Elis [28]

Hi there! The answer is y = 1/6x + 1/2

To find the inverse function x and y need to switch places.

$y = 6x - 3 \\ x = 6y - 3$

Now rewrite the equation, until it will be in standard form (slope-intercept form) again.
$x = 6y - 3$

Add 3.
$x + 3 = 6y$

Switch sides.
$6y = x + 3$

Divide both sides by 6.
$y = \frac{1}{6} x+ \frac{3}{6} \\ y = \frac{1}{6} x + \frac{1}{2}$

Hence, the answer is y = 1/6x + 1/2.
~ Hope this helps you!
