The solution for y= -4 and for x it is -2. You can also write it as (-2,-4). If you need all the steps let me know. I can show you. Otherwise, Hope it helps.
You work this problem out by evaluating the given formula using the numbers given in the problem statement. It tells you the principal amount is $700, the interest rate is 4% = 0.04, and the time is 1 year.
The given formula is ...
A = Pe^(rt)
Any scientific or graphing calculator can evaluate that with the numbers filled in:
700×e^(0.04×1) ≈ 728.56754 ≈ 728.57 (rounded)
_____
"e^x" is generally a function the calculator is able to perform, so you don't need to know the value of "e".
I believe the answer is the last one ∠M ≡ ∠C. for triangles which are congruent the corresponding angles are equal while the corresponding sides are equal. Therefore, if three pairs of sides of two triangles are equal in length (SSS), then the triangles are congruent. In addition if two pairs of angles of two triangles are equal in measurement, and the included sides are equal in length, then the triangles are congruent.
