Which values for A and B will create infinitely many solutions for this system of equations

Mathematics
1 answer:
nikdorinn [45]4 years ago
8 0

Answer:

  A = 6, B = -15

Step-by-step explanation:

In order for there to be infinitely many solutions, the equations must be dependent. That is, one of them must be a multiple of the other. Here, the multiplier is apparently -1.

Comparing coefficients on the left, we see that the bottom equation has an x-coefficient that is the opposite of the one in the top equation. So, to make y-coefficients opposite, the top equation should read ...

  4x -6y = 15 . . . . . A = 6

Carrying that through, the bottom equation should read ...

  -4x +6y = -15 . . . . . B = -15

Perimeter of a trapezoid with bases x, 2x and sides x+2 and 2x-3
Simora [160]

Answer:

Perimeter of trapezoid = 6x - 1

Step-by-step explanation:

a trapezoid has two bases (x and 2x) and two sides ( x+2 and 2x-3)

To find the perimeter you add all both bases and both sides

Perimeter of trapezoid = x + 2x + (x+2) + (2x-3); add x's

Perimeter of trapezoid = 6x + 2 -3 ; subtract the numbers

Perimeter of trapezoid = 6x - 1

alex41 [277]

Answer: The percent of the total was spent on veterinarian bills is 27.70% ( approx).

Step-by-step explanation:

Given, In 2011, Americans spent approximately $50.9 billion on their pets.

i.e. Total amount they spent on pets = $50.9 billion

Amount spent for veterinarian bills.  = $14.1 billion was for veterinarian bills.

Then, the percent of the total was spent on veterinarian bills would be :

\dfrac{\text{Amount spent for veterinarian bills. }}{\text{Total amount they spent on pets}}\times100\\\\=\dfrac{14.1}{50.9}\times100\\\\=27.7013752456\approx27.70\%

Hence, the percent of the total was spent on veterinarian bills is 27.70% (approx).
