Answer:

The system is consistent; it has one solution ⇒ D

Step-by-step explanation:

A consistent system of equations has at least one solution

The consistent independent system has exactly 1 solution

The consistent dependent system has infinitely many solutions

An inconsistent system has no solution

In the system of equations ax + by = c and dx + ey = f, if

a = d, b = e, and c = f, then the system is consistent dependent and has infinitely many solutions
a = d, b = e, and c ≠ f, then the system is inconsistent and has no solution
a ≠ d, and/or b ≠ e, and/or c ≠ f, then the system is consistent independent and has exactly one solution

In the given system of equations

∵ -2y + 2x = 3 ⇒ (1)

∵ -5y + 5x = 12 ⇒ (2)

→ By comparing equations (1) and (2)

∵ -2 ≠ -5

∵ 2 ≠ 5

∵ 3 ≠ 12

→ By using the 3rd rule above

∴ The system is consistent independent and has exactly one solution

∴ The system is consistent; it has one solution

Explain the role of the GCF in factoring a polynomial.

andreev551 [17]

The Greatest Common Factor (GCF) is the largest number that will be divided evenly into that number. For example, for 24, the GCF is 12. For a polynomial, the GCF is the largest polynomial<span> that will divide evenly into that polynomial.</span>

One taxi leaves at a stop at every 6 minutes a second taxi leaves the stop every 9 minutes if they leave at 4.00 p.m at what tim

qaws [65]

Both taxis will leave together at 04:18 PM after 04:00 PM

Step-by-step explanation:

We have to use the LCM to find the time on which both will leave at the same time,

Given

Departure interval for first taxi = 6 minutes

Departure interval for second taxi = 9 minutes

We have to find the LCM of 9 and 6

So,

Factors of 6: 6,12,<u>18</u>,24,30,36,42,48,54,60

Factors of 9: 9,<u>18</u>,27,36,45,54,63,72

The LCM is 18.

So,

Both taxis will leave together at 04:18 PM after 04:00 PM
