Answer:

C

Step-by-step explanation:

When a system of equations has an infinite number of solutions, this means that the equations will be identical.

Convert the given equation to y = mx + b form.

2y - 4x = 6

2y = 4x + 6

y = 2x + 3

Answer A, B, and D don't apply.

Answer C is the answer because if it is the same equation but with a negative sign in front of each term.  If you switch the signs on every single term, you will have the given equation.

Answer:

C

Step-by-step explanation:

A system of equations has infinitely many solutions when the two lines representing the equations coincide. i.e. the two equations are the same or a multiple of each other.

2y - 4x = 6

2y = 4x + 6

2y = 2(2x + 3)

y = 2x + 3

-y = -(2x + 3)

-y = -2x - 3

Hence the other equation is -y = -2x - 3

A commercial airline makes a flight each day from New York to Paris, France. The aircraft seats 524 passengers and serves 2 meal
nadya68 [22]
Start by multiplying the amount of passengers by 2 (for amount of meals)

524×2= 1,048

That will equal to 1,048, which is the amount of meals given out for a full plane in one day.

Now multiply that by 7 (for one week) and you'll get your answer!

524×2= 1, 028 × 7 = 7, 336 meals

7, 336 meals are given out in a one week time span on a fully packed plane.

What is the least common multiple of 4 and 12?
podryga [215]

Answer:

The lcm (least common multiple) of 4 and 12 is 12.

Step-by-step explanation:

Find the prime factorization of 4

4 = 2 × 2

Find the prime factorization of 12

12 = 2 × 2 × 3

Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the LCM:

LCM = 2 × 2 × 3

LCM = 12

Hello! Please help thanks
kogti [31]

Answer:

A. \frac{5}{13}

Step-by-step explanation:

Hi there!

We are given right triangle PQR, with PR=5, RQ=12, and PQ=13

We want to find the value of sin(Q)

Let's first recall that sine is \frac{opposite}{hypotenuse}

In reference to angle Q, PR is the opposite side, RQ is the adjacent side, and PQ is the hypotenuse

So that means that sin(Q) would be \frac{PR}{PQ}

Substituting the values of PR and PQ gives sin(Q) as \frac{5}{13}, which is A

Hope this helps!
