Answer:
A = -10.5
Step-by-step explanation:
To find the value of "A", you can plug x = 2 and f(x) = 3 into the equation. This will allow you to simplify and find the value of "A".
f(x) = 4x³ + Ax² + 7x - 1 <---- Original equation
3 = 4(2)³ + A(2)² + 7(2) - 1 <---- Plug x = 2 and f(x) = 3 into equation
3 = 4(8) + A(4) + 14 - 1 <---- Solve 2³ and 2²
3 = 32 + A(4) + 14 - 1 <---- Multiply 4 and 8
3 = 45 + A(4) <---- Combine like terms
-42 = A(4) <---- Subtract 45 from both sides
-10.5 = A <---- Divide by 4
If A = -10.5, the final equation would look like this:
f(x) = 4x³ - 10.5x² + 7x - 1
Answer:
10.5 Dozens
Step-by-step explanation:
if each gingerbread man has 3, then you will be able to make 126 gingerbread mans, but you asked for dozens, so 126 gingerbread mans divided by 12, which is a dozen, will equal to 10.5 dozens
Brainliest would be appreciated, Thank you.
Answer:
Between 0 and 3: decreasing
Between 3 and 4: constant (stays the same)
Between 4 and 8: decreasing

Answer:
Not sure what you're asking but 120.4 is
one hundred
two tens
and four tenths
Answer:
it’s 8 and 2 and 4 and 0
Step-by-step explanation:
this is because when you multiply 2x the x is an 8 so 2 times 8 is 16 then minus 2 is 14 which is greater than -4 same for my other answer
