Answer:

D. -5 <= x < 1

Step-by-step explanation:

the values under the square-root radical must not be negative, AND

the value of the denominator must not be 0 or negative

x+5 >=0  or x >= -5

and 1-x > 0 or x < 1

So the answer is -5 <= x < 1

Mrac [35]

Answer:

  • 2 1/4 pounds of blueberries

Step-by-step explanation:

Blueberries - b, raspberries - x

<u>Equations as per question:</u>

  • 4/5x = 9/5
  • x = 9/5 : 4/5
  • x = 9/5 *5/4
  • x = 9/4
  • x = 2 1/4
