Answer:
h) (3 - 2b)/4b²
k) (2b - 3a)/ab³
Step-by-step explanation:
h) 3/4b² - 1/2b
multiply 1/2b, both top and bottom, by 2b, so 1/2b = 2b/4b²:
3/4b² - 2b/4b² = (3 - 2b)/4b²
k) 2/ab² - 3/b³
multiply 2/ab², both top and bottom, by b, so 2/ab² = 2b/ab³:
multiply 3/b³, both top and bottom, by a, so 3/b³ = 3a/ab³:
2b/ab³ - 3a/ab³ = (2b - 3a)/ab³
The conjugate of a binomial, is pretty much just the same thing, but with a different sign in between, so,
pelican + canary conjugate => pelican - canary
a + b conjugate => a - b
-a - b conjugate => -a + b
and so on, therefore
x - √2 conjugate => x + √2
Answer: He invest $2500 in account with rate of interest 5% and invest $3500 in account with 6% of interest so that the total interest earned is $335.
Step-by-step explanation:
Given: The rate of interest for account 1= 5%=0.05
The rate of interest for account 2= 6%=0.06
Let P be the Principal amount Keisha invested in the account with 5% interest .
Then the amount she will invest in account with 6% interest= 6000-P
Time = 1 year
The simple interest is given by:-

Simple interest for account 1=
Simple interest for account 2=
According to the question,
Total Interest =$335

So, he invest in account with 5% interest= $2500
He invest in account with 6 % interest=$6000-$2500=$3500
