Answer:

<h2> x = 324 </h2>

Step-by-step explanation:

<h3>y=Kx</h3>
  • <u>make k the subject of formula</u>
<h3>=> Kx = y</h3><h3>=> k = y/x</h3>
  • <u>add the value of y = 18 when x = 2.</u>
<h3>=> k = 18/2</h3>
  • divide 18 by 2
<h3>=> k = 9</h3>

<em><u>What is the value of x when y = 36?</u></em>

<h3>=> x = Kx</h3>
  • <u>substitute k equals to 9 and from the question y equals to 36 into this equation</u>
<h3>=> x = 9(36)</h3>
  • <u>multiply 36 by 9</u>
<h3>=> x = 324</h3>

Given a polynomial f(x), if (x + 7) is a factor, what else must be true? Help plzzz im running out of time
solong [7]
Answer: f(-7) = 0
For the factored form of f(x), if x = -7, then one of the factors will be equal to 0, since (-7 + 7) = 0. This will cause the entire y-value to be 0, because anything multiplied by 0 = 0.
