Step-by-step explanation:
Answer:
The value of x is 6 and -6. The smallest value of x is -6
Step-by-step explanation:
2/3 x² = 24
solving this equation for finding the value of x.
Multiply both sides by 3/2
x² = 24 * 3/2
x² = 72/2
x² = 36
Now, to find the value of x taking square root on both sides
√x² = √36
x= ±6
So, the value of x is 6 and -6. The smallest value of x is -6
Answer: f(x) = x/2 + 4.
where f(x) is the number of stamps that Tom has, and x is the number of stamps that Myrna has.
Step-by-step explanation:
The statement is:
"Tom has four more than half the stamps that Myrna has"
For how is written, we can model the number of stamps that Tom has as a function f(x).
f(x) represents the number of stamps that Tom has, and x is the number of stamps that Myrna has.
Then:
"four more than a number" is written as:
N + 4 (where N is the number)
"Half the stamps that Myrna has" is written as:
x/2.
Then the whole statement can be modeled as:
f(x) = x/2 + 4.
notice that we have x/2, and f(x) must be a whole number, so Myrna must have an even number of stamps (in that case x/2 will be integer)
