\\ \sf\longmapsto \dfrac{x^2-1}{x^2+5x+4}\leqslant 0

  • Solving denominator

\\ \sf\longmapsto x^2+5x+4>0

\\ \sf\longmapsto x^2+4x+x+4>0

\\ \sf\longmapsto x(x+4)+1(x+4)>0

\\ \sf\longmapsto (x+4)(x+1)>0

\\ \sf\longmapsto x>-4\:or x>-1

  • Hence x\neq-1
  • x can't be 0 as it makes function undefined

\\ \sf\longmapsto -4

The housing market in Dallas, Texas, experienced a 9.8% increase in the past year. If the median home price was $96,812 one year
JulijaS [17]

Answer:  $106,300

<u>Step-by-step explanation:</u>

A = P(1 + r)

  • A is the accrued amount (balance)
  • P is the principal (initial amount)
  • r is the rate --> convert to a decimal

Given: P = 96,812    r = 9.8% --> 0.098

A = 96,812(1 + 0.098)

   = 96,812(1.098)

   = 106,299.576

rounded to the nearest dollar is $106,300
