Answer:
$5,500
Step-by-step explanation:
Let A be the amount invested at 3%, B the amount at 4%.
Total value:
1.A%2BB=8000
Interest:
Multiply eq. 1 by -3 and add to eq. 2,
-3A-3B%2B3A%2B4B=-24000%2B29500
highlight%28B=5500%29
Then from eq. 1,
A%2B5500=8000
highlight%28A=2500%29
Subtract 110 and 8.75 and you get 101.25 then divide that by 9 and you get 11.25
For this case we have the following functions:

By definition of composition of functions we have:

Then substituting:

So:

Answer:

Answer:
u can find the answer in calculate
Answer:
Step-by-step explanation:
note : distance between A(X1,Y1) an B (X2,Y2) is :
AB= √((X2 - X1)² + (Y2 - Y1)²)
in this exercice : X1 = -3 X2 = - 4 Y1 = 5 Y2 = 1
continue .....calculate AB
