Percentage Calculator: What is 57 percent of 3.09? = 1.7613.
Answer:
x = 5/2
x = 2 1/2
x = 2.5
Step-by-step explanation:
3x - 1 - (x + 3) = 1
3x - 1 - x - 3 = 1
2x - 1 - 3 = 1
2x - 4 = 1
2x = 1 + 4
2x + 5
2x = 5
x = 5/2 → 2 1/2 → 2.5 ( can be written in any of these forms depending on what you need to do)

Answer:
The solutions are x = 1.24 and x = -3.24
Step-by-step explanation:
Hi there!
First, let´s write the equation:
log[(x² + 2x -3)⁴] = 0
Apply the logarithm property: log(xᵃ) = a log(x)
4 log[(x² + 2x -3)⁴] = 0
Divide by 4 both sides
log(x² + 2x -3) = 0
if log(x² + 2x -3) = 0, then x² + 2x -3 = 1 because only log 1 = 0
x² + 2x -3 = 1
Subtract 1 at both sides of the equation
x² + 2x -4 = 0
Using the quadratic formula let´s solve this quadratic equation:
a = 1
b = 2
c = -4
x = [-b± √(b² - 4ac)]/2a
x = [-2 + √(4 - 4(-4)·1)]/2 = 1.24
and
x = [-2 - √(4 - 4(-4)·1)]/2 = -3.24
The solutions are x = 1.24 and x = -3.24
Have a nice day!
Answer:
Nominal Interest Rate: Does not consider inflation provides a sense of purchasing power
Real Interest Rate: It describes the stated interest rate on an account and also considers inflation
Step-by-step explanation:
Real interest rate can be defined as the Nominal interest rate minus the inflation rate.
Nominal Interest Rate is the interest rate without taking into account the inflation
-4x-2(8x=1)=-(2x-10)
-First, use the distributive property.
So distribute -2 to 8x=1 then distribute the negative - to (2x-10)
So it'd be: -4x-16x=-2=-2x+10
Then combine like terms:
-20x=-2=-2x+10
-18x=-2=10
-18x=8
Divide -18x by 8
x=-2.25
