Answer:
$3714.18
Step-by-step explanation:
From the question;
Amount invested is $3300
Rate of interest 3% per year compound interest
Time is 4 years
We want to determine the amount that accrued after 4 years
In this case we are going to use the compound interest formula;
That is;
where A is the amount, P is the principal , r is the rate of interest and n is the time taken.
Therefore;
= $3714.18
Therefore, the amount accrued after 4 years is $3714.18
Answer:
Step-by-step explanation:
Number 2 first:
See the graph below for a hint. (Do you know how to use Desmos ?)
factoring seems to make no sense for but "guess and check" seems to work. I tried 4 for x, but that proved false. 3 for x made sense. You get
so -9 +6 +4 = 1 is true. So (3,1)
x+y=4 becomes 3 + 1 = 4 Also true
According to the graph, (0,4) would also be a solution, so (3,1) and (0,4)
Part 1:
Factor as
set each equal to 0 and get
x = -3 and x = -1 so the solutions seem be (-3,0) and (-1,0)
y = 2x + 6 factors to 2(x +3)
(-1,0) doesn't work!
But Desmos shows something else as a solution set for both:
(1,8)
y=2x+6 substitute values 8=2(1) +6 8=2+6 True
y = . Substitute values
8= 1+4+3 True
