The formula is
A=p e^rt
A future value 900
P present value 800
E constant
R interest rate 0.11
T time?

We need to solve for t
T=[log (A/p)÷log (e)]÷r
T=(log(900÷800)÷log(e))÷0.11
T=1.07 years round your answer to get 1 year

How many solutions does the equation 3x + 6 = −1 − 3 + 4x have? (5 points)

lianna [129]

Answer:

The equation has only one solution which is:

$x = 10$

Step-by-step explanation:

Given the equation

$3x\:+\:6\:=\:-1\:-\:3\:+\:4x$

Let us solve the equation to determine the type of the equation

$3x\:+\:6\:=\:-1\:-\:3\:+\:4x$

subtract the number: -1 - 3 = -4

$3x+6=4x-4$

subtract 6 from both sides

$3x+6-6=4x-4-6$

$3x=4x-10$

subtract 4x from both sides

$3x-4x=4x-10-4x$

$-x=-10$

Divide both sides y -1

$\frac{-x}{-1}=\frac{-10}{-1}$

$x=10$

Therefore, the equation has only one solution which is:

$x = 10$

X = a number

X + 12 = 9

Rearrange to get X on its own.

X = 9 - 12

X = -3
