Step-by-step explanation:

We have to make x the subject:

y = x² + 4x + 4.

=> y = (x + 2)² by completing the square

=> x + 2 = ±√y

=> x = ±√y - 2

Therefore the inverse is y = ±√x - 2.

Elise picks 6 pounds of apples.She uses 1/2 pounds to make 1 container of apple sauce. How many containers of applesauce can Eli

Marina CMI [18]

Answer:

Step-by-step explanation:

Mass of apples = number of containers × mass in each container

6 lb = No of containers × ½ lb

No of containers = 6/½

To divide a whole number by a fraction, invert the fraction and change divide to multiply.

6/½ = 6 × 2/1

Multiply the numerator by the whole number.

6 × 2/1 = 12/1

Simplify the fraction.

12/1 = 12

Elise can make 12 containers of applesauce.
