Answer:
It moves horizontally 1/2 units to the left
It moves vertically 2 units up
Step-by-step explanation:
∵ y = Acos(Bx - C) + D
∵ y = 2 - 3cos(2x + 1)
∴ The phrase of shift:
∵ The horizontally shift is -C/B = - 1/2 = -1/2
∴ It moves 1/2 units to the left
∵ The vertically shift is D
∴ It moves 2 units up
Answer:
C
Step-by-step explanation:
Ms. Barcht's savings account can be modeled with the expression
50 + 25x
Mrs. Greene's savings account can be modeled with the expression
75x
Since the question is how many weeks Mrs. Greene will have more money than Ms. Bracht. we use an inequality to contain the all the solutions.
Mrs.Greene > Ms. Bracht
75x > 25x + 50
A ratio compares two quantities.
How may days are in May? <span>31
How many days in a year? </span>365
Now, we are being asked to compare may to a year.
Answer: 31 to 365
Now, the other is easy also.
A triangle has 3 sides, and a square has 4.
Answer: 3 to 4
Find equal ratio's
8/12 = 2/3 = 4/6 = 16/24
20/25 = 4/5 = 40/50 = 80/100
Done! Enjoy! :) I hope I helped your son. Take care.
