A:amount of money invested in the account with 3% simple interest
B: amount of money invested in the account with 4.5% simple interest
a+b=25000 ——>a=25000-b
0.03a+0.045b=900
30a+45b=900000
2a+3b=60000
2(25000-b)+3b=60000
50000-2b+3b=60000
B=10000
A=25000-10000=15000
Answer:
Step-by-step explanation:
In a given triangle, the sum of every angle is always 
. Here, we are given a right angle (
), as well as another 
angle. Simply subtracting from 180 will give us the answer.
Answer:
here's your answer v
Step-by-step explanation:
The first number in the sequence, , is -2.
Each number after that is the previous number multiplied by -2.
etc. We start by stating that .
Now we need to show that for all n greater than or equal to 2, each number in the sequence is the previous number multiplied by -2.
this is the answer.
Answer:
a1+= -2; an = - 2a-1, n > 2
Answer:
The first term, 5x^3, can be eliminated.
The exponent on the first term, 5x^3, can be changed to a 2 and then combined with the second term, 2x^2
Step-by-step explanation:
The highest degree allowed in a quadratic function is 2, so the third degree term (the first term) needs to be eliminated or changed. The change shown above is one of many possibilities.
