PLEASE HELP ASAP! I have no idea where to start with this.

Answer:

h (-5) = 41/4 or 10.25

h (-2) = -3

h (3) = 25/4 or 6.25

Step-by-step explanation:

h (-5) = 1/4(-5)^2 + 4

h (-5) = 1/4(25) + 4

h (-5) = 41/4 or 10.25

h (-2) = -3 (this is given to you in the function)

h (3) = 1/4 (3)^2 + 4

h (3) = 1/4(9) + 4

h (3) = 25/4 or 6.25

Drag each tile to the correct box.

Answer:

  1. 15 - 7 (Parentheses)
  2. 3² (Exponents)
  3. 8 × 2 (Multiplication)
  4. 40 ÷ 8 (Division)
  5. 5 + 9 (Addition starting from the leftmost)
  6. 14 + 16 (Addition after the first addition operation)

Concept:

When encountering questions that ask for simplifying expressions through operation, following the PEMDAS method would be easier:

  • <u>P</u>arentheses
  • <u>E</u>xponents
  • <u>M</u>ultiplication
  • <u>D</u>ivision
  • <u>A</u>ddition
  • <u>S</u>ubtraction

Therefore, the whole process of simplifying the given expression should follow the PEMDAS method. <u>For extra</u>, whenever there are two occurences of the same operation, then prioritize the leftmost and go right.

Hope this helps!! :)

Please let me know if you have any questions or need further explanation
