Change divide sign to multiplication sign, and flip second fraction
= 41/21 × 23/8

multiply top numbers together and multiply bottom numbers together
= (42×23)/(21×8)
=943/168

You can do the multiplicative inverse by mutiplying 41/21 and 8/23. But, you have to switch the second number to 23/8. Once it's switched, you just multiples straight across. So, it is 943/168. Just simplify it

What’s the correct answer
Sergio039 [100]
----------------------------------------------------------------------------
Find constant a.
----------------------------------------------------------------------------
Given that g(4) = 8

--------------------------------------
Substitute x = 4
--------------------------------------
g(4) = a(4)² + 24 = 8

16a + 24 = 8

--------------------------------------
Take away 24 from both sides
--------------------------------------
16a = 8 - 24

16a  = -16

--------------------------------------
Divide by 16 on both sides
--------------------------------------
a = -1

Now that we know that a = -1, plug it back to the equation.

g(x) = -x² + 24

--------------------------------------
Find g(-4)
--------------------------------------
g(-4) = - (-4)² + 24
g(-4) = -16 + 24
g(-4) = 8

----------------------------------------------------------------------------
Answer: 8
----------------------------------------------------------------------------
