Answer:
x= 1 ±√21/3
x= 2.52753
x= - 0.527525
Step-by-step explanation:
-(-6) ±√-6² - 4 (3) (-4) / 2(3)
6±√36 -(-48) / 6
6±√84/6
6±2√21/6
6/6 ±2√21/6
1±√21/3
1+ √21/3 = 2.52753
1-√21/3= - 0.527525
Answer:
2 and -1/2
Step-by-step explanation:
perpendicular lines have slopes that have opposite signs and are reciprocals
Answer:
Step-by-step explanation:
let x represent the denominator then x - 3 represents the numerator.
Increase the numerator by 1, that is x - 3 + 1 = x - 2
Increase the denominator by 3, that is x + 3, then fraction
= ( cross- multiply )
2(x - 2) = x + 3, that is
2x - 4 = x + 3 ( subtract x from both sides )
x - 4 = 3 ( add 4 to both sides )
x = 7
Thus original fraction is
=
Answer:
His money earned $36 after 3 months
Step-by-step explanation:
* Lets revise the rules of simple interest
- Simple Interest Equation (Principal + Interest)
A = P(1 + rt)
- Where:
• A = Total amount (principal + interest) future amount
• P = Principal Amount
• I = Interest Amount
• r = Rate of Interest per year in decimal; r = R/100
• t = Time Period involved
* To calculate the interest I use the formula
I = P × r × t
* Lets solve the problem
- The rate is annual
- The interest calculated after 3 months
∴ I = P × R/100 × t/12
∵ P = $3600.00
∵ R = 4%
∵ t = 3 month
∴ I = 3600.00 × 4/100 × 3/12 = $36
* His money earned $36 after 3 months
