DedPeter [7]

Answer:

  • 7

Step-by-step explanation:

<h3>Given</h3>
  • f(n) = n ^ 4 + 5n ^ 3 + 2n ^ 2 - 5n + 13
<h3>To find </h3>
  • f(-2)
<h3>Solution</h3>

<u>Substituting n with -2</u>

  • f(-2) =
  • (-2)^4 + 5(-2)^3 + 2(-2)^2 - 5(-2) + 13 =
  • 16 - 40 + 8 + 10 + 13 =

What are the zeros of the function defined by 2x + 11x- 6?
asambeis [7]
Note --> As you're writing 'zeroes' , I assume there is a typing mistake and you've given a Quadratic equation in the question

f(x) = 2 {x}^{2} + 11x - 6 \\ \\ f(x) = (2x - 1)(x + 6) = 0

Hence , the roots are 1/2 and -6
The graph attached confirms the same ,

Hope it helps you :)

If 5/4x + 1/2 = 2x - 1/2 what is x
stellarik [79]

Answer:

x=\frac{4}{3}

Step-by-step explanation:

We can solve the equation by isolating x through order of operations. We use PEMDAS in reverse by undoing SADMEP or subtraction, addition, division, multiplication, exponents, and parenthesis.

\frac{5}{4}x+\frac{1}{2} =2x-\frac{1}{2}


1. We simplify any parenthesis. Have none. So move on to the next step!

2. We undo any subtraction or addition by doing the inverse on both sides.

\frac{5}{4}x+\frac{1}{2}-\frac{1}{2}  =2x-\frac{1}{2}-\frac{1}{2} \\\frac{5}{4}x =2x-1

3. Now subtract an x term from both sides.

\frac{5}{4}x-2x =2x-2x-1\\\frac{5}{4}x -\frac{8}{4}x =-1\\-\frac{3}{4}x=-1

4. Divide both sides by the coefficient of x.

-\frac{3}{4}x =-1\\x=-\frac{4}{3} (-1)\\x=\frac{4}{3}
