Answer:

  a.  (-1/2, 5)

Step-by-step explanation:

The coefficients of x have opposite signs, so the x-terms can be eliminated by adding the two equations.

  (2y -12x) +(3y +12x) = (16) +(9)

  5y = 25 . . . . . . simplify

  y = 5 . . . . . . . . .divide by 5

This matches only answer choice A.

__

<em>Check</em>

The other part of answer choice A is x = -1/2. We can test this to make sure it works:

  2(5) -12(-1/2) = 16

  10 + 6 = 16 . . . . . . true, the selected answer works OK

Mekhanik [1.2K]

Answer:

False

False

True

True

True

Step-by-step explanation:

There cannot be an orange bead in the bag. FALSE

they never said how many colors are in the bag so there is always a possibility.

There must be exactly 1 yellow bean in the bag. FALSE

Just because Ryan only selected 1 yellow bean doesn't mean there is only 1 in the bag.

After 15 trials, Ryan has selected exactly 6 white beads. TRUE

2/5 = 6/15. Ryan has selected 6 white beads

After 16 trials, the experimental probability of selecting a blue bead is 1/4. TRUE

Ryan has selected 4/16 blue beads at the 16th trial.

After 17 trials, the experimental probability of selecting a red bead is 5/17. TRUE

at trial 17, the red bean ratio is 5/17.

1/3 = 5/15 and then 2 more trials make it 5/17.

yanalaym [24]
----------------------------------------------------------------------------------------
Given information
----------------------------------------------------------------------------------------
Side length of a square = 2x² + 1
Perimeter of the square = 4(2x² + 1)

----------------------------------------------------------------------------------------
If x = 3.5, find perimeter
----------------------------------------------------------------------------------------
Perimeter of the square = 4(2(3.5)² +1)
Perimeter of the square = 4(2(12.25) +1)
Perimeter of the square = 4(24.5 +1)
Perimeter of the square = 4(25.5)
Perimeter of the square = 102 inches

----------------------------------------------------------------------------------------
Answer: Margot will need 102 inches of the ribbon.
