(hope this helps :P)
Answer:
Step-by-step explanation:
can stay untouched, but has to be changed to . Now that they have they have the same denominator, you can add them. , which can be simplified, which is .
We observe that the relationship between the variables is linear.
Therefore, we look for an equation of the form:
Where,
m: slope of the line
b ': intersection with the y axis
a: independent variable
b: dependent variable
The value of b 'occurs when a = 0.
We have then:
(See table)
Then, the value of the slope is found using the following formula:
Substituting values:
Rewriting:
Thus, the linear equation is:
Rewriting:
Answer:
The equation is:
C.) 3a-b=10
Answer:
geometric sequence
Step-by-step explanation:
If the sequence is geometric then there is a common ratio r between consecutive terms.
= =
= =
= =
Then sequence is geometric with common ratio r = ( ≈ 0.67 )
Answer:
a= -3/8
b= 1/8
Step-by-step explanation:
To remove i from the denominator, we need to multiply the numerator and denominator by -i
This simplifies to
This further simplifies to
This can be rewritten as
a= -3/8
b= 1/8
