n=-2 i got this answer because i combined like terms first like 2n-n
we get just n after
and then, we subtract the 5 from both sides to get it on the opposite side of the equal sign.. we get x=-2
Do it ur self etc so don't ask me
Answer:
The rule says that to find the number of years required to double your money at a given interest rate, you just divide the interest rate into 72. For example, if you want to know how long it will take to double your money at eight percent interest, divide 8 into 72 and get 9 years.
Answer:
a = 5, b = -3 and c =1
Step-by-step explanation:
The standard form of a quadratic equation is expressed as;
f(x) = ax² + bx + c
Given the expression
f(x) = 5x² = 3x - 1
f(x) = 5x² - 3x + 1
Comparing with the general formula;
ax² = 5x²
a = 5
bx = -3x
b = -3
c = 1
Hence a = 5, b = -3 and c =1
