Step-by-step explanation:
x = number of 6 month periods
y = total money in account
After 10 years:




After 18 years:




Answer:
3/4*x - 3/4*8=12
3/4x -6=12
3/4x=12+6
3/4x=18
x=24
Step-by-step explanation:
multiply 3/4 into the content inside the brackets
have -3/4*8 cross the equal sign changing its sign from - to +
divide both sides by 3/4
Answer:
C
Step-by-step explanation:
Given the logarithmic equation

First, notice that

So, there is no possible solutions, all possible solutions will be extraneous.
Solve the equation:

then

Hence,
and
are extraneous solutions
Complete the square for the given equation
x² - 2x + ____ + y² - 2y + _____ = 98
x² - 2x + (1) + y² - 2y + (1) = 98 + (1) + (1)
(x - 1)² + (x - 1)² = 100
(x - 1)² + (x - 1)² = 10²
Now the equation is in the form (x - h)² + (y - k)² = r²
