To solve this you'll plug in the ordered pairs and if the answer is equal then it is the answer.
A: 2 = 3(0) - 2
2 = 0 - 2
2 ≠ -2
B: 1 = 3(1) - 2
1 = 3 - 2
1 = 1
C: 1 = 3(-3) - 2
1 = -9 - 2
1 ≠ -11
D: 0 = 3(2) - 2
0 = 6 - 2
0 ≠ 4
So the answer choice B is the solution to the given equation.
Hope this helps :)
Then simplify and you should have 2/5
Answer:
5x - 10
Step-by-step explanation:
3(3x) - 2(2x+3) + (-4)
first, distrubute any terms into the parentheses, we want to get rid of those first
3(3x) = 9x
-2(2x+3) = -4x -6
(-4) = -4
our new equation is:
9x - 4x - 6 - 4
combine the terms together:
5x - 10 is our final answer
Answer:
6.32 years
Step-by-step explanation:
To get the time taken to triple the amount invested, we must first establish the compound interest formula. When a principal amount P is invested for a time n at a rate r percent, the amount A after n years may be expressed as
A = P (1 + r)^n
Hence if $1,225 is to triple, the amount will be
= $1,225 *3
= $3,675
The time n for this to happen may be computed through the equation
$3,675 = $1,225 ( 1 + 0.19)^n
3 = 1.19^n
take the log of both sides
log 3 = log 1.19^n
using the law of logarithms that log a^b = b log a
n log 1.19 = log 3
n = log 3 / log 1.19
n = 6.32 years
