How do you solve -2 1/2+3/4÷3/8
Step-by-step explanation:
1. use PEMDAS (Parentheses, Exponent, Multiplication & Division, Addition & Subtraction). you would do 3/4 divided by 3/8 first.
3/4 / 3/8 = 2
2. add 2 to -2 1/2 (or if it's easier to understand, do 2 minus 2 1/2)
-2 1/2 + 2 = -1/2 OR 2- 2 1/2 = -1/2
answer is -1/2

Which is a better deal?
An ice company charged $6.02 for 7 bags of ice. If a
convenience store sold 6 bags of ice for $5.52, which is a
better buy?
Explain/Justify your answer
Answer:
The $6.03 for 7 bags of ice is a better deal
Step-by-step explanation:
In order to find out which is a better deal we find the unit price.
To find the unit price we do the cost divided by how many bags of ice.
6.02 divided by 7 = 0.86, so the unit price is 0.86/1
5.52 divided by 6 = 0.92, so the unit price is 0.92/1
Finally, we can see which has a lower unit price which is the $6.03 for 7 bags of ice

Determine if the following function is Even,Odd or neither. f(x) =4x+3
Answer:
It is odd
Step-by-step explanation:
For example let's substitute 1 for x
f(x) = 4(1)+3
4+3
f(x) = 7 this is odd
Let's substitute 2
f(x) = 4(2)+3
8+3
f(x) = 11 this is odd
This means no matter what you substitute for x, it will be odd

Which of the following parent functions has a domain and range of all real
numbers?
A. Cubic
B. Reciprocal
C. Quadratic
D. Absolute value
Parent functions has a domain and range of all real numbers is a Cubic function
Given :
We need to find the parent function that has a domain and range of all real
numbers.
Domain is the set of all x values and range is the set of y values.
For any cubic function there is no restriction for x
For each value of x there is a y value
So, domain and range of cubic function is set of all real numbers
For reciprocal function , there will be x in the denominator . So there will be some restriction for x.
For any quadratic function , domain is set of all real numbers. For quadratic we get U shaped graph . It means there is some restriction for y.
So range cannot be real numbers
For absolute value function , we get V shaped graph . so there is some restriction for y. Range cannot be all real numbers.
parent functions has a domain and range of all real numbers is a Cubic function

Modeling Real-World Scenarios with Sine and Cosine Functions
The table below shows the illuminated percentage of the moon on a lunar cycle of 28 days. The relationship can be described using a cosine function.
Answer:
0 and 0
Step-by-step explanation:
it stays the same 7 to 17 is 7
14 to 21 is 7 etc...
The amplitude of the function is 48 units.
The period of the function is 28 units.
The graph has a vertical shift of 48 unit.
To determine the amplitude and period of the cosine function that describes the relationship between the day (d) and the illuminated percentage of the moon (%), we can analyze the given data:
d %
0 48
14 96
21 48
28 0
Amplitude:
The amplitude of a cosine function represents half the difference between the maximum and minimum values of the function.
So, (96 - 0) / 2
= 48 units.
Period:
The period of a cosine function is the length of one complete cycle.
Therefore, the period of the function is 28 units.
Vertical shift:
The vertical shift represents the displacement of the graph vertically.
The graph has a vertical shift of 48 unit.
