What is the value of k?
yawa3891 [41]

Answer:

<h2>             k = 3</h2>

Step-by-step explanation:

The vertex is (d, e)

for quadratic function: f(x) = ax² + bx + c  we have:

d = -b/a    and    d = (x₁ + x₂)/2  

a = 1,   b = k,   x₁ = -4,    x₂=-2      

so:

d = -b/a = -k/1 = -k   and   d = (x₁ + x₂)/2 = (-4-2)/2 = -3

-k = -3

k = 3

  • Division Property of Equality
  • Addition Property of Equality
  • Subtraction Property of Equality<u> </u>

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

5a - 10b = 45

<em>b</em> = 3

<u>Step 2: Solve for </u><em><u>a</u></em>

  1. Substitute in <em>b</em> [Equation]:                                                                                5a - 10(3) = 45
  2. Multiply:                                                                                                             5a - 30 = 45
  3. [Addition Property of Equality] Add 30 on both sides:                                  5a = 75
  4. [Division Property of Equality] Divide 5 on both sides:                                  a = 15
