Explanation:
When you divide mixed fractions you first convert them to improper fractions. Further, dividing by a number
a
b
is equivalent to multiplying by its reciprocal i.e. for dividing by
a
b
, you multiply by
b
a
i.e. numerator and denominators reversed. Hence,

Step-by-step explanation:
x² + x - 2 = 0
x² + 2x - x - 2 = 0
x(x + 2) - 1(x + 2) = 0
(x + 2)(x - 1) = 0
x + 2 = 0 and x - 1 = 0
x = -2 and x = 1
So, f(x) has no solution if x = -2 or 1
Domain = {x | x ≠ 2 and x ≠ 1}
Answer:
53.51 years
Step-by-step explanation:
FV = PV e⁽ⁿˣ⁾
FV = Future Value = $5000
PV = Present Value = $1500
n = Interest Rate = 2.25%
x = time in years = ?
e = mathematical constant = 2.7183
So,
5000 = 1500 e⁽⁰°⁰⁰²⁵ˣ⁾
50 / 15 = e⁽⁰°⁰⁰²⁵ˣ⁾
㏑ (3.3333) = 0.0225x ㏑ (2.7183)
1.2040 = 0.0225x
x = 53.51 year
So, If compounded continuously at an APR of 2.25% the amount invested in an account of $1500 will accumulate to $5000 in 53.51 years.
Answer:
-18
Step-by-step explanation:
Put -195 as y and solve
-195 = 9x - 33
Add 33 to both sides
-162 = 9x
Divide both sides by 9
-18 = x
Well you see it is a really simple one to do x should be 9 trust me its 9 even tho it dont sound correct
