What is the solution to the following equation x+y=6 x-y=2

1 answer:

4 0

X+y = 6
x-y = 2

Add both equations,
2x = 8
x = 4

Substitute it in equation 1,
4+y = 6
y = 6-4 = 2

In short, x = 4 & y = 2

Hope this helps!

You can use your calculator to divide it out and find that

$-\dfrac{8}{11}=-0.\overline{72}$

or, you can make use of your knowledge of the decimal equivalent if 1/11 (=0.90909...) and multiply that by -8 to get -0.727272... as above.

explain:
y-2=-x+3
y= -x+3+2
so y= -x+5

Answer:

It is the graph of g(x) shifted 5 units right and 2 units down.

Step-by-step explanation:

Given : f(x)=log_2(x−5)−2

the parent function g(x)=log_2(x)

To get f(x) , 5 is subtracted from x

If we add any number with x then we shift left

If we subtract any number from x then we shift right

Here 5 is subtracted from x , so we shift 5 units right

Also -2 at the end

If we add any number at the end , then we shift up

if we subtract any number at the end , then we shift down

Here 2 is subtracted at the end , so we shift 2 units down

It is the graph of g(x) shifted 5 units right and 2 units down.
