Item is a wigger are you at $35 it is now priced at a discount of 95% of the regular price​
Roman55 [17]

Answer:

$1.75

Step-by-step explanation:

35×.95 (Because percent is just a decimal)

=33.25

35-33.25 (Because it's a discount, so we are subtracting)

=1.75

(I'm guessing your question is asking how much it is after the discount.)

If f(x) = 4x^3 + Ax^2 + 7x - 1 and f(2) = 3, what is the value of A?<br> (^ = powers)
bekas [8.4K]

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
