Answer:
y= -90x+250
Step-by-step explanation:
From the information given, the equation would be that the amount in the account would be equal to -90 that is the amount you withdraw from the account each week multiply for x that is the number of weeks plus $250 that is your initial balance:
y= -90x+250, where
y= amount in the account
x= number of weeks.
Answer:
Step-by-step explanation:
- log 2x + log (x - 5) = 2
- log (2x(x - 5)) = 2
- 2x(x - 5) = 10²
- 2(x² - 5x) = 100
- x² - 5x - 50 = 0
- x² + 5x - 10x - 50 = 0
- x(x + 5) - 10(x + 5) = 0
- (x - 10)(x + 5) = 0
- x = 10
- x = -5, this root is discounted as log should be positive.
Correct choice is 3.
Answer:
they and we would be 124
Step-by-step explanation:
124÷4=31
f(x) = 3x + 5/x
f(a + 2) = 3.(a + 2) + 5/(a + 2)
Alternative C.
Answer:
1/12 or 8.33% is the probability
Step-by-step explanation:
Assuming the number cube has 6 sides there is 1/6 chance of getting a 3 and a 1/2 chance of getting tails when flipping a coin. Multiplying 1/6 by 2 to get 1/12.
