A system of equations has infinitely many solutions. If 2y – 4x = 6 is one of the equations, which could be the other equation?

1 answer:

5 0

Answer:

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

If a person can see 6 miles from a height of 25 feet, how far can a person see from a height of 196 feet?

Aleksandr-060686 [28]

Answer:

47,04 miles

Step-by-step explanation:

you can clearly see something 20 feet away that you should be able to see from that distance. If a person can see 6 miles from a height of 25 feet, by dividing 196 by 25 we can get the following calculation

196 ÷ 25 = 7,84

Then you gan multiply

7,84 × 6 = 47,04 miles

Or equal to 75703,542 meters

Do I add all the GPAs together and then add all the GPAs above Salley and then subtract them from each other?

solong [7]

No you add them all together and then you divide the number of GPA's to get the mean. You go from greatest to lowest to figure out the median and to find the mode excepts my mind. <span />
