To find out how much you need when you need a fraction of a number like 1/3 of 9, you can multiply the whole number by the fraction in most cases.
In some cases however, you can convert the whole number into a fraction and then divide it to get the amount in fractional units that you require.
For example:
1/3 of 9
Convert 9 to a fraction.
1/3 / 9/1
1/3 x 9/1 = 3/9
Therefore you would need 3 of 9 for 1/3.
(-1+6i)+(-4+2i) =====> -5+8i (simplified)
Answer:
Roster Form of M = {-2, -1 , 0, 1}
Set Builder Form of M = {x : x is an integer and -3 < x ≤ 1 }
Step-by-step explanation:
Roster Form: A set is said to be in roster form if each element of the set is written distinctly in the set with commas in between them.
Set Builder Form: A set is said to be in set builder form if all the set elements are represented by describing their properties.
Now, here M is the set of integers that are greater than -3 and less than or equal to 1.
So, by definition of the set forms,
Roster Form of M = {-2, -1 , 0, 1}
Set Builder Form of M = {x : x is an integer and -3 < x ≤ 1 }
Answer:
x < 4
Step-by-step explanation:
Step 1: Write inequality
2x < 8
Step 2: Divide both sides by 2
x < 4
We see here that any value of <em>x</em> less than 4 will work. So numbers like 1, 0, -124 or even -14687206589174 would work.
Answer:
The answer is A.
Step-by-step explanation:
Lets call f(x)=y, so y= 4*(3*x-5), we want to find 'x', using 'y' as a the variable.
Now lets change the name of 'y' to 'x', and 'x' to f^-1(x).
f-1(x) = (x+20)/12
