It’s x=5 5/7 because you don’t want the x being negative. you make the x positive and since the “-5 5/7” is negative you make it positive.

Determine which ordered pairs fall on the graph of f(x) = -2x-1
Pavlova-9 [17]

Answer:

No order Pair fall on the graph

Step-by-step explanation:

The given Function is

f(x)= -2x -1       ...............(i)

Now to see whether these ordered pairs Lay on it we will put each ordered pair in the equation (i)


Lets take first ordered pair (1,1)

here x = 1

putting it in (i) gives

f(1)= -2(1) -1

f(1)= -3

this is not equal to 1 so the order pair (1,1) does not fall on function f(x)= -2x -1

Lets take second ordered pair (-1,-4)

here x = -1

putting it in (i) gives

f(-1)= -2(-1) -1

f(-1)= 1

this is not equal to -4 so the order pair (-1,4) does not fall on function f(x)= -2x -1


Lets take third ordered pair (-2,-1/8)

here x = -2

putting it in (i) gives

f(-2)= -2(-2) -1

f(-2)= 3

this is not equal to -1/8 so the order pair (-2,1/8) does not fall on function f(x)= -2x -1


Lets take fourth ordered pair (0,-1/2)

here x = 0

putting it in (i) gives

f(0)= -2(0) -1

f(0)= -1

this is not equal to -1/2 so the order pair (0,-1/2) does not fall on function f(x)= -2x -1

What is the solution to this system of linear equations? x − 3y = −2 x + 3y = 16
True [87]

Answer:

so x=5 1/3 and

y= -2 2/3

Step-by-step explanation:

x-3y= -2x+3y=16. First we need to move all variables to one side of the equation and whole numbers to the other side of the equation. I see

x-3y+2x-3y=16. -3y-3y equals to -6y. 2x+x=3x. so 3x-6y=16. Lets take out the -6y so our equation would be 3x=16. x would equal 5 1/3. Now lets put back -6y into our equation. Let's now substitute x as 0. 3 times 0 equals 0 so our equation would now be -6y=16 which equals to -2 2/3.

so x=5 1/3 and

y= -2 2/3

What is the simplified form of -64 1/3? Need Help ASAP, will make brainliest answer :)!!!
alexgriva [62]
-64 1/3

disregard the negative sign for the moment...
to turn a mixed number into an improper fraction, take ur whole number (63) and multiply it by ur denominator (3) and u get (64 * 3) = 192....now add that to ur numerator (1) and u get (192 + 1) = 193...now put that over ur original denominator (3) and u get 193/3.....now put ur negative sign back....and u have - 193/3.....simplified form, does not reduce
