Answer:
Option C is the correct answer.
Step-by-step explanation:
Looking at the functions given,
Initial amount deposited into the account is $150 This means that the principal is
P = 150
It was compounded quarterly. This means that it was compounded 4 times in a year. So
n = 4
The rate at which the principal was compounded is 3%. So
r = 3/100 = 0.03
It was compounded for x years. So
t = x years
The formula for compound interest is
A = P(1+r/n)^nt
A = total amount in the account at the end of t years. Therefore, the
function that models the value in x years of an investment at 3% annual interest compounded quarterly would be
150 (1+0.03/4)^4×x
150 (1 +.0075)^4x
Answer:
8,865 = 6,000 + (0.05)(t)
Step-by-step explanation:
t=years
P=$6,000
A=$8,865
r=0.05

Step-by-step explanation:
Answer:
y = 5x
Step-by-step explanation:
you can use the Slope-Intercept form of a line, which is:
y = mx + b where 'm' is the slope, and 'b' is the y-intercept
to find the slope, select any two points:
we can use (0,0) and (2,10)
now subtract the y-values and the x-values to get this fraction:
slope = 10-0 / 2-0
slope = 10/2 or 5/1
the y-intercept can be seen and is 0
therefore, equation of this line is:
y = 5x + 0 or
y = 5x
Answer:
Step-by-step explanation:
1/3(x+6)=12
x+6=12/(1/3)
x+6=(12/1)(3/1)
x+6=36/1
x+6=36
x=36-6
x=30
Answer: 30
--------------------
12(x+1/6)=8
x+1/6=8/12
x=8/12-1/6
x=8/12-2/12
x=6/12
simplify
x=1/2
Answer: 1/2
------------------
-3(x+2)=-18
x+2=-18/-3
x+2=6
x=6-2
x=4
Answer: 4
-----------------
-3(x-2)=21
x-2=21/-3
x-2=-7
x=-7+2
x=-5
Answer: -5
-------------------
-5(4-x)=-40
4-x=-40/-5
4-x=8
x=4-8
x=-4
Answer: -4
------------------
1/4(6-x)=1/4
6-x=(1/4)/(1/4)
6-x=1
x=6-1
x=5
Answer: 5
