Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = -4x² + 6x - 4

f(5) is x = 5

<u>Step 2: Evaluate</u>

  1. Substitute:                     f(5) = -4(5)² + 6(5) - 4
  2. Exponents:                    f(5) = -4(25) + 6(5) - 4
  3. Multiply:                         f(5) = -100 + 30 - 4
  4. Add:                               f(5) = -70 - 4
  5. Subtract:                        f(5) = -74

Answer:

  f(3) = -20

Step-by-step explanation:

To find the value of a function, substitute the number for the variable and do the arithmetic.

  f(x) = -2x^2 +x -5 . . . . . . given

  f(3) = -2(3^2) +(3) -5 . . . . function value for x = 3

  f(3) = -2(9) +3 -5 = -18 +3 -5

  f(3) = -20

A company owns two manufacturing
SVETLANKA909090 [29]

Answer:

3x+24 more widgets

Step-by-step explanation:

A company owns two manufacturing plants:

  • 1st plant: 8x+17 widgets;
  • 2nd plant: 5x-7 widgets.

To find how many more items the first plant produces daily than the second plant, we have to subtract from the number of widgets the first plant produces the second plant produces. So,

(8x+17)-(5x-7)\\ \\=8x+17-5x+7\ [\text{Eliminate brackets}]\\ \\=(8x-5x)+(17+7)\ [\text{Combine the like terms}]\\ \\=3x+24

3x to the power of two minus x<br> Factor by gcf
algol13

Answer:

After factorizing the given expression we get the value as x(3x-1).

Step-by-step explanation:

Given:

3x^2-x

We need to factorize the given expression using GCF.

Solution:

3x^2-x

Now GCF means Greatest common factor.

From the given 2 numbers we need to find the greatest common factor.

3\times x\times x- 1 \times x

In the given expression GCF is 'x'.

Hence we can say that;

x(3x-1)

Hence After factorizing the given expression we get the value as x(3x-1).
