Answer:
1 2/3-6/8=11/12
Step-by-step explanation:
convert to a common denomitor.
1 2/3= 1 8/12
6/8= 9/12
1 8/12-9/12=11/12

A log function is a way to find how much a number must be raised in order to get the desired number. The correct option is A.
What is Logarithm?A log function is a way to find how much a number must be raised in order to get the desired number.
[tex]a^c =b[/tex]
can be written as
[tex]\rm{log_ab=c[/tex]
where a is the base to which the power is to be raised,
b is the desired number that we want when power is to be raised,
c is the power that must be raised to a to get b.
For example, let's assume we need to raise the power for 10 to make it 1000 in this case log will help us to know that the power must be raised by 3.
The solution set of the given equation can be found as shown below.
log₄(x-3) + log₄(x+3)=2
log₄[(x-3)(x+3)] = 2
Taking antilog,
(x-3)(x+3) = 4²
(x-3)(x+3) = 16
x² - 3² = 16
x² = 16 + 3²
x² = 25
x = ±5
Substitute the value of x as -5 and 5, to verify if the equation is verified.
The only value for which the equation is satisfied is 5.
The above solution can be verified by plotting the graph.

Determine whether or not the following graph represents two quantities that are proportional to each other. Explain your reasoning.
Answer:
The quantities are not proportional.
Step-by-step explanation:
The values, x and y, do not begin or pass through the origin, (0,0). This means they are not proportional.
The graph represents two quantities are not proportional to each other.
What is Proportional?A relationship is proportional if each pair of data values are related in the same way, by multiplying by a factor. You can recognize a proportional relationship by looking at data, an equation, or a graph.
Given:
As, A relationship is proportionate if its graph is a line or ray that passes through the origin.
and, It is not proportionate if the line or ray does not go through the origin. Additionally, if anything is not linear, it is not proportional.
Here the graph also does not pass through the origin.
Hence, the graph is not proportional.

A pet store is selling dogs for $140 and cats for $70. If 28 pets were sold and they made $3,360. Write a system of equations that matches the situation
Answer:
x+y=28
70x+140y=3360
8 cats, 20 dogs were sold
Step-by-step explanation:
Let x=cats y=dogs
We know that a total of 28 pets were sold which means that
x+y=28
We also know that they made 3360 which means that
70x+140y=3360
It doesn't really say if you need to solve this but I will anyways
We use the first equation (x+y=28) and subtract 28 and y from both sides to get
x-28= -y we can then divide both sides by -1 so y can be a positive
-x+28=y
This is what y equals in terms of x and so we can plug this in for y in the second equation
70x+140(-x+28)=3360
Distribute the 140 and get
70x-140x+3920=3360
Add like terms and subtract 3920 to get
-70x=-560
divide both sides by -70 and get
x=8
We now know that 8 cats were sold and can plug this value into any equation to solve for y ( I will be using the first one because that's easiest)
8+y=28
subtract 8 and get
y=20
A system of equations that matches the situation is:
1) d + c = 28.................Equation 1
2)140d + 70c = 3360............Equation 2
This question has to do with Algebraic equations.
Let's represent
Number of dogs = d
Number of cats = c
A pet store is selling dogs for $140 and cats for $70. If 28 pets were sold and they made $3,360.
We have two algebraic systems of equations for the above statements
1) d + c = 28.................Equation 1
2) $140 x d + $70 x c = $3,360
140d + 70c = 3360............Equation 2

A tree casts a shadow of 48ft. A man who is 6ft. tall casts a shadow of 4 ft. How tall is the tree?
Answer:
72ft.
Step-by-step explanation:
Could be mis-understanding the problem, but if the man is 6ft tall and having a 4ft shadow, then you want to figure out how many times 4 goes into 48, which signifies how many times taller the tree is compared to the man.
48/4= 12
next you want to multiply 6 by 12, which shows exactly how tall the tree is.
6x12= 72.
Answer:
72ft
Step-by-step explanation:
so you would divide 6 and 4 and that is 1.5
then you would do 48ft x 1.5 which is 72ft
so the tree is 72ft tall

Evaluate f(x)= -6+12 when x= -3,x=0, and x=1.
When x= -3, f(x)= , when x=0,f(x)= , and when x=1,f(x)= .
Given :
A function, f(x) = -6 + 12
To Find :
The value of f(x) when x= -3, x= 0 and x=1.
Solution :
Given function is f(x) = -6 + 12 .
Simplifying above function, we get :
f(x) = 6
Now, the given function is independent of x.
So, for any value of x the the value of functions remains constant.
Hence, this is the required solution.

In a sixth grade class at Lincoln Middle School, there are 3 boys for every 4 girls in the class.
Fill in the blank: The ratio of boys to girls in the class is __________.
If there are between 20 and 30 students in the class, what could be the actual number of boys and girls in the class?
Answer:
There are multiple possibilities. One is there are 12 boys, and 16 girls. 12+16= 28 which is between 20 and 30. That would be 12:16, which can be simplified to 3:4. There is also 9 boys, and 12 girls. that would be 9:12, which can be simplified to 3:4. Also, 9 + 12 = 21, which is between 20 and 30.
