Elimination using addition and subtraction
6x-2y=32
4x-2y=18

x=7, y=5

Step-by-step explanation:

6x-2y=32

4x-2y=18

Subtract the second equation from the first equation

  6x-2y=32

-  4x-2y=18

 2x      = 14

Divide each side by 2

2x/2 =14/2

x=7

Now substitute x=7 into the first equation to find y

6*7-2y=32

42 -2y = 32

Subtract 42 from each side

42-42 -2y = 32-42

-2y = -10

Divide each side by -2

-2y/-2 = -10/-2

y =5

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
