You get it by cross multiplication
10×9÷3=30 and if you want to check
30 over 9 =3.333
10 over 3 = 3.333
Answer:
-3
Step-by-step explanation:
-7b = 21
/ -7 / -7
b = -3
3√(-50) = 3√(-1*50)=3i√(25*2) = 3*5i√2=15i√2
He needs to save $150 each of the last two months.
The equation is:
[e^x] [e^(2x)] = 4
1) Applying property of multiplication of powers wiith same base =>
e ^ (x + 2x) = 4
=> e ^ (3x) = 4
2) Applying logarigth properties
3x = ln(4)
=> x = ln(4) / 3 ≈ 1.38629 / 3 ≈ 0.4621
Answer: x = ln(4) / 3 ≈ 0.4621
