Answer:

A

Step-by-step explanation:

x + 2y = 2

-1x + 1y = 5 Is not the correct answer!!!

The options are

a) 2x + 4y = 4

-3x +y = -1

b) 2x + 4y = 4

7x + 5y = -1

c) 2x + 4y = 4

7x - y = 5

Answer:

x+2y=2

-1x+1y=5

Step-by-step explanation:

Any system whose equations have the following characteristic

x+2y=2

-1x+1y=1

Is equivalent to the original system, since the differ in a number, the first equation is divided by 2 and the second by 5, we can say any system is equivalent to the original when it is escalated  by a factor between its functions.

A regular pentagon shares a common center with a regular hexagon. If `bar(LM)` || `bar(AB)`, across how many lines of reflection
choli [55]

our lines of symmetry is made limited by the presence of the pentagon. If we slice the pentagon into two, the only line of symmetry we could create would be the line intersecting O and the median of LM. Other lines would not create a symmetrical half.

Therefore the line of reflection is only 1.

One number to the right of the decimal will mean there are two numbers to the left of the decimal.

When rounding to 50 as the nearest ten the number needs to be between 45 and 54.

Using the 3 numbers shown that would be 48.3
