The algebraic expression for the word phrase "the product of a number and 3" as a variable expression is 3z
<h3>How to write an algebraic expression for the word phrase "the product of a number and 3" as a variable expression?</h3>
The word phrase is given as:
"the product of a number and 3"
Represent the number with z
So, the word phrase can be rewritten as:
"the product of a number z and 3"
The product of a number z and 3 is represented as:
z * 3
When evaluated,, the expression becomes
z * 3 = 3z
Hence, the algebraic expression for the word phrase "the product of a number and 3" as a variable expression is 3z

2x3x4= 24 cubic units. You multiply the length by the width by the height.
Answer:
![f(x)=5\sin(\pi x)](https://tex.z-dn.net/?f=f%28x%29%3D5%5Csin%28%5Cpi%20x%29)
This is one possibility fitting the criteria.
Step-by-step explanation:
I was thinking about using the sine curve because we have that it starts at
and not
. The factor of 5 came from the amplitude.
So we know so far our function looks like this
.
However the inside will be effected since the period is 2.
has a period of
.
has a period of
.
We want
to have a period of 2 so we want to solve
.
So multiply both sides by b:
![2\pi=2b](https://tex.z-dn.net/?f=2%5Cpi%3D2b)
Divide both sides by 2:
![\frac{2\pi}{2}=b](https://tex.z-dn.net/?f=%5Cfrac%7B2%5Cpi%7D%7B2%7D%3Db)
.
So the function we have from the given information is:
![f(x)=5\sin(\pi x)](https://tex.z-dn.net/?f=f%28x%29%3D5%5Csin%28%5Cpi%20x%29)
Answer:
(x + 5) - 9
Step-by-step explanation:
An expression is a mathematical phrase that contains a variable and a constant, but not an equal sign. Using key words from the given verbal expression, we can make an algebraic expresion:
'nine less than' = subtract 9 or - 9
'the sum of x and 5' = addition of 'x' and '5' or x + 5
put them together: (x + 5) - 9
