3. how many solutions does the system of equations have? 4x = -12y + 16 and x + 3y = 4 a.) one b.) two c.) infinitely many d.) none 4.) how many solutions does the system of equations have? y = 6x + 2 and y = 6x + 4 a.) one b.) two c.) infinite d.) none 5.) how many solutions does the system of equations have? x - 2y = 6 and 3x - 6y = 18 a.) one b.) two c.) infinitely many d.) none i don't know how to do these, and explanation of how these are done would be nice.

Part 3) Option C infinitely solutions

Part 4) Option D none

Part 5) Option C infinitely solutions

Step-by-step explanation:

Part 3) we have

-----> convert to standard form

-----> equation A

-----> equation B

Multiply the equation B by

------>

The equation A and the equation B are the same

therefore

The system has infinitely solutions

Part 4) we have

------> equation A

------> equation B

equation A and equation B are parallel lines, because has the same slope

the slope is equal to

therefore

The system has no solution

Part 5) we have

------> equation A

------> equation B

Multiply the equation A by

----->

The equation A and the equation B are the same

therefore

The system has infinitely solutions

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5
