Answer:
He has saved $140.
Step-by-step explanation:
Since 35% translates to 0.35, 35% of 400 is (0.35)(400) = 140
Answer:
f(g(x)) = 15x³ - 5
Step-by-step explanation:
how confusingly described.
let me try and summarize what I understood :
f(x) = 3x² - 5
money earned when baking x cookies.
g(x) = sqrt(5x³)
the amount of cookies baked in x hours.
f(g(x)) now calculates how much money she earns when baking for x hours.
it is basically very simple : instead of f(x) we have f(g(x)), so g(x) is used as argument/variable in f instead of just plain x.
therefore,
f(g(x)) = 3×(sqrt(5x³))² - 5
with x now representing the baking hours, but f(...) calculating the overall money earned, by implicitly (!) calculating the amount of cookies baked in that time and taking that result automatically to calculate the earned money.
let's simplify this a little bit more.
f(g(x)) = 3×(sqrt(5x³))² - 5 = 3×(5x³) - 5 = 15x³ - 5
Answer:
x < -24(option
Step-by-step explanation:
-¼x - 12 > -6
Add 12 to both sides
-¼x - 12+12 > -6+12
-¼x > 6
Divide both sides by -¼
x < 6 ÷ -¼
Please note that the inequality sign changes when divided by negative (minus). This is a rule in inequalities.
x < 6 × -4
x < -24
