Answer:
Values for x = -1 + 7i and -1 - 7i
Step-by-step explanation:
we have an equation,
(x+1)^2 = -49
We need to solve this equation for all values of x:
(x+1)^2 = - 49
Taking square root both sides
√((x +1)^2) = √-49
x + 1 = ± 7i
Subtract both sides by 1
x = -1 ± 7i
Hence we get two values for x = -1 + 7i and -1 - 7i
Answer:
y = 1/4 +3
Step-by-step explanation:
On week 1, we started with a deposit of $200. Every week from that point on, we place a deposit of $55.
We know y is total amount of money (deposits) in the bank account.
We also know x represents the number of weeks.
On week 1, we would have $200 in the back account.
On week 2, we would have $200 + $55 or $255 in the bank account.
So, we could build an expression of 55(x - 1) + 200 which is equal to y.
So, y = 55(x - 1) + 200 is the answer.
If you would like to know the number of minutes of long-distance calls you made, you can calculate this using the following steps:
3.3 cents = $0.033
m = $3.40 / 3.3 cents
m = $3.40 / $0.033 = 3.40 / 0.033
m = 103.03 minutes
The correct result would be <span>103.03 minutes.</span>
