Answer: The required system of equations representing the given situation is
Step-by-step explanation: Given that Sam needs to make a long-distance call from a pay phone.
We are to write a system to represent the situation.
Let x represent the number of minutes Sam talked on the phone and y represents the total amount that he paid for the call.
According to the given information,
with prepaid phone card, Sam will be charged $1.00 to connect and $0.50 per minute.
So, the equation representing this situation is
Also, if Sam places a collect call with the operator he will be charged $3.00 to connect and $0.25 per minute.
So, the equation representing this situation is
Thus, the required system of equations representing the given situation is
Answer:
.
Step-by-step explanation:
V² + 3v - 5 = 0
v = -(3) ± √((3)² - 4(1)(-5))
2(1)
v = -3 ± √(9 + 20)
2
v = -3 ± √(29)
2
v = -3 ± 5.38
2
v = -1.5 ± 2.69
v = -1.5 + 2.69 or v = -1.5 - 2.69
v = 1.19 or v = -3.19
In partial-quotients<span> division, it takes several steps to find the </span>quotient<span>. At each step, you find a </span>partial<span> answer (called a </span>partial quotient); then you find the product of thepartial quotient<span> and divisor and subtract it from the dividend. Finally, you add all the</span>partial quotients<span> to find the final </span>quotient<span>.</span>
