Answer:
In mathematics, equality is a relationship between two quantities or, more generally two mathematical expressions, asserting that the quantities have the same value, or that the expressions represent the same mathematical object. The equality between A and B is written A = B, and pronounced A equals B.[1][2] The symbol "=" is called an "equals sign". Two objects that are not equal are said to be distinct.
Step-by-step explanation:
For example:
{\displaystyle x=y}x=y means that x and y denote the same object.[3]
The identity {\displaystyle (x+1)^{2}=x^{2}+2x+1}{\displaystyle (x+1)^{2}=x^{2}+2x+1} means that if x is any number, then the two expressions have the same value. This may also be interpreted as saying that the two sides of the equals sign represent the same function.
{\displaystyle \{x\mid P(x)\}=\{x\mid Q(x)\}}{\displaystyle \{x\mid P(x)\}=\{x\mid Q(x)\}} if and only if {\displaystyle P(x)\Leftrightarrow Q(x).}{\displaystyle P(x)\Leftrightarrow Q(x).} This assertion, which uses set-builder notation, means that if the elements satisfying the property {\displaystyle P(x)}P(x) are the same as the elements satisfying {\displaystyle Q(x),}{\displaystyle Q(x),} then the two uses of the set-builder notation define the same set. This property is often expressed as "two sets that have the same elements are equal." It is one of the usual axioms of set theory, called axiom of extensionality.[4]
Answer:
No.
Step-by-step explanation:
This is because 5:2 could mean there are 5 circles to 2 triangles and 2:5 could mean 2 circles to 5 triangles.
5 circles is not the same as 2 circles as 2 triangles is not the same as 5 triangles.
Answer:
P=3
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−2=5p+3p−8−6p
−2=5p+3p+−8+−6p
−2=(5p+3p+−6p)+(−8)(Combine Like Terms)
−2=2p+−8
−2=2p−8
Step 2: Flip the equation.
2p−8=−2
Step 3: Add 8 to both sides.
2p−8+8=−2+8
2p=6
Step 4: Divide both sides by 2.
2p2=62
p=3
Answer:
The exponential growth formula.
Answer: Salid should get $38.75 of change.
Step-by-step explanation:
Hi, to answer this question we have to analyze the information given:
- <em>Quantity of window trim bought: 35 feet
</em>
- <em>Cost per feet: $1.75
</em>
- <em>Amount paid: $100
</em>
First, we have to calculate the total cost, by multiplying the Quantity of window trim bought (35) by the price per feet (1.75)
35 x 1.75 = $61.75
Finally, to calculate the change that Salid should get, we have to subtract the total cost (61.75) to the amount paid (100)
100-61.75=$38.75
