Hi there!
f(x) = 6x - 4
g(x) = 3x² - 2x - 10
To find (g(f(x)), substitute in the equation of f(x) as 'x' in g(x):
g(f(x)) = 3(6x - 4)² - 2(6x - 4) - 10
Simplify:
= 3(36x² - 48x + 16) - 2(6x - 4) - 10
= 108x² - 144x + 48 - 12x + 8 - 10
= 108x² - 156x + 46
So u speak spanish right, cool! I speak a little i mean, i understand every thing but my mouth goes ruohuernorng when i try to speak spanish lol
9] Rocky Falls would be 13.4°F at sunrise.
Use the equation 23.1 + (-9.7) = x, where x is the temperature at sunrise (13.4)
23.1 + (-9.7) = 23.1 - 9.7
Solve so that x = 13.4
10] Jamie originally had $263.25 in her account.
Just add how much she spent (135.75 + 32) to how much she ended up with (95.5)
135.75 + 95.5 + 32 = 263.25
If you are asking how much she has if she started out with $95.50 before going to the Mets game,
95.5 - (135.75 + 32) = -$72.25
Or 95.5 - 135.75 - 32, same result of -72.25
