Answer:
-6
Step-by-step explanation:
Substitutet -7 for y in -3(9+y): -3(9 - 7) = -3(2) = -6
No
They are not equivalent.
It will take 13.42 years.
The equation for this is in the form y=a(1+r)ˣ, where a is the initial deposit, r is the interest rate as a decimal number and x is the amount of time. Using our information, we have the equation
8000 = 4000(1+0.053)ˣ
8000 = 4000(1.053)ˣ
Divide both sides by 4000:
8000/4000 = 4000(1.053)ˣ/4000
2 = 1.053ˣ
We will use a logarithm to solve this:

Answer:
3x-x+2=4
Step-by-step explanation:
A straw that is 16 centimeters long fits inside a glass. The height of the glass is 14 centimeters. Find the radius of the glass.
--------------
If the radius is more than 16 cms, it obviously fits.
---
Not a well stated problem.
If you want the minimum radius, it's a right triangle problem, but only if the straw is a line.
If a diameter of the straw is given, it's a difficult but realistic problem.
