Sergio039 [100]

Answer:

 = $ 4344.05

Step-by-step explanation:

Using the formula

A = P (1 +r/n)^nt

Where A is the amount accumulated, P is the principal amount, n is the number of interest periods, t is the time taken in years.

A = $4369.20

r = 0.033

n = 4

t = 21/12

Therefore;

$4369.20 = P ( 1 + 0.033/4)^ (21/12×4)

$4369.20 = P (1.000825)^7

$4369.20 = 1.005789 P

  P = $4369.20/1.005789

   <u>  = $ 4344.05</u>

.. pls help me....!!!!! Determine whether the point (-2,4) satisfy y&lt;3x+5,y=3x+5 or y &gt;3x+5..​
natima [27]

Given:

The point is (-2,4).

To find:

Whether the point (-2,4) satisfy y or y >3x+5.​

Solution:

We have a point (-2,4).

Substituting x=-2 in 3x+5 and check whether it is greater, equal or less than y value, i.e., 4.

3x+5=3(-2)+5

=-6+5

=-1

-1 is less than 4.

3x+5

3x+5

In can be written as

y>3x+5

Therefore, the given point (-2,4) satisfy y >3x+5.
