I’m confused, is 1/52 and 52/1 the same?
Answer: No
Step-by-step explanation:
Because 52/1 is just plain 52
But 1/52 is one thing out of 52 of them.
So 52/1 is just the number 52 versus 1/52 is one of fifty-two.
Answer:
Yes, 1/52 is the same as 52/1 because 52/1 is the inversed fraction of 1/52. Inversed fractions is a fraction with the denominator and numerator swapped.

On which interval(s) is the function f(x) = x3+3x^2−4x−12 increasing?
The intervals over which the function is increasing are -
x ∈ (- ∞, - 2.5) and x ∈ (0.5, ∞). We can write it as one single set (S) as -
S = (- ∞, - 2.5) ∪ (0.5, ∞).
What is increasing or decreasing interval of a function?The interval in which the y - coordinate of the points gets larger, or the graph gets higher as it moves from left to right over the interval is called increasing interval. Similarly, the interval in which the y - coordinate of the points gets smaller or the graph gets lower as it moves from left to right over the interval is called decreasing interval.
Given is the following function f(x) -
f(x) = x³ + 3x² - 4x - 12
First, we will plot the graph of this function. The graph is attached with the answer. On the graph, there are two black dots. From the definition of increasing functions, we know that the interval along which the y - coordinate gets larger is called increasing interval of the function. The first interval over which the function is increasing is- x ∈ (- ∞, - 2.5). The second interval over which the function is increasing is- x ∈ (0.5, ∞).
Therefore, the intervals over which the function is increasing are -
x ∈ (- ∞, - 2.5) and x ∈ (0.5, ∞). We can write it as one single set (S) as -
S = (- ∞, - 2.5) ∪ (0.5, ∞).

write an equation un point slope form for the line through the gives point with the given slope.
(-3,4);m=2/3
a. y+3=2/3(x-50
b. y+5=(2/3)(x+3)
c. y-5=2/3(x-3)
d. y-5=2/3(x+3)
To find the answer, all we need to do is plug in the slope and point they gave us into the Point Slope Formula!
The point slope formula is ...
[tex]y - y_{1} = m ( x - x_{1} )[/tex]
So lets put them in!
y - 4 = 2/3 (x - (-3))
Tip: remember when you subtract a negative number, it turns into adding !
So our final answer is probably D (I think you may have put a typo)

What is the constant of proportionality? Write your answer as a whole number or decimal.
The constant of proportionality is 4, while the equation is given as y = 4x.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A variable can either be dependent or independent. A dependent variable depend on other variable while an independent variable does not depend on other variables.
Let x represent number of mines and y represent the number of gems. Since this is a proportional relationship, hence:
y = kx; where k is the constant of proportionality
From the table when y = 4, x = 1, hence:
4 = k(1)
k = 4
y = 4x
The constant of proportionality is 4, while the equation is given as y = 4x.

some two step equations can be written in the form ax+b=c where a b and c are constants and x is the varible A. write the equation ax+b=c in terms of x B use the formula to solve 3x+7=19 and 1/2x - =5
A. The equation for x is c - b/a
B. x = 4
x = 10
How to determine the equationGiven the equation;
ax + b = c
Let's make 'x' the subject of formula by expressing it in terms of other variables
We have;
ax = c - b
Divide both sides by the coefficient of 'x'
ax/a = c - b/ a
x = c - b/a
B. 3x + 7 = 19
Let's solve for x
3x = 19 - 7
3x = 12
Make 'x' the subject
x = 12/ 3
x = 4
1/2x = 5
cross multiply
x = 5 × 2
x = 10
Thus, the equation for x is c - b/a

given
inductive reasoning
definitions
algebraic properties
Answer:
Algebraic properties can be used as "reasons" in a two-column proof.
Step-by-step explanation:
Algebraic properties can be used as "reasons" in a two-column proof.Let's take an example:
Given: F = 9/5C + 32
Prove: C = 5/9(F-32)
Statements Reasons
1) F = 9/5C + 32 1) Given
2) F-32 = 9/5C 2) subtraction
3) 5/9(F-32) = C 3) multiplication
4) C = 5/9(F-32) 4) symmetric property
Therefore, we conclude that Algebraic properties can be used as "reasons" in a two-column proof.
A school carnival sold tickets to ride on a Ferris wheel. The charge was $3.00 for adults and $2.00 for students. If 54 tickets were sold for a total of $141.00, how many adult tickets were sold?
Answer:
33 adult tickets and 21 student tickets
Step-by-step explanation:
We will create a system of equations.
Let x = the number of adult tickets sold and let y = the number of student tickets sold
x + y = 54
3x + 2y = 141
We can cancel out the y by multiplying the first equation by -2.
-2x - 2y = -108
3x + 2y = 141
Adding these equations together we get:
x = 33
Plugging this into the equation, we have:
38 + y = 54
y = 21
There were 33 adult tickets and 21 student tickets

The value of sallys caravan decreased by x% in the third year. At the end of the third year the value of sallys caravan was £16,500. Work out the value of x
The value of x is 100 - 1650000/y where the initial value of the Sally's caravan be represented by y
How to work out the value of x?The given parameters are
New value = £16,500
Rate of decrease = x%
Let the initial value of the Sally's caravan be represented by y
So, we have the following equation
Initial value * (1 - Rate of decrease) = New Value
This gives
y * (1 - x%) = 16,500
Divide both sides of the equation by y
So, we have
1 - x% = 16500/y
This gives
x% = 1 - 16500/y
Multiply through by 100
x = 100 - 1650000/y
Hence, the value of x is 100 - 1650000/y where the initial value of the Sally's caravan be represented by y
