Answer:

C = 4: dependent system
C ≠ 4; independent, consistent system with solution (0, -2)

Step-by-step explanation:

If you divide the first equation by 2, you get ...

4x -3y = 6

If C=4, the second equation would be identical to this, giving a dependent system of equations with an infinite number of solutions.

If you want a system of equations with one solution, the value of C must be anything except 4. (That system will have the solution (x, y) = (0, -2).)

Answer:

$m = \frac{-y+x}{2}$

Step-by-step explanation:

$2m - x + 3y = 2y$

Take $-x$ and $+3y$ on the other side of the equal to sign:

$2m = 2y +x-3y$

Now solve for y:

$2m = -y +x$

Take 2 one the other side of the equation:

$m = \frac{-y +x}{2}$

Hope this helps :)

A stadium's normal ticket price is $78. As a special promotion they offer 15% off. What is the price of the discounted ticket?

alexgriva [62]

ANSWER: $66.30

WORK:
to find 15% off, multiply by 0.15.
78 x 0.15 = 11.7

note: this is the percent off, so it's subtracted to find the sale price.

78 - 11.70 = 66.3
