For the following system, if you isolated x in the first equation to use the substitution method, what expression would you substitute into the second equation? Expression 1
−x + 2y = −6

Expression 2
3x + y = 8

sorry not sure

step-by-step explanation:

step-by-step explanation: 4 cause 2+2=4

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.

y=-2.5x+12.5

step-by-step explanation:

5y=2x+10

y=0.4x+2

slope=-2.5

5=-2.5*3+b

b=12.5
