Solve the system of equations by substitution. What is the solution for x? (1 point) 2x + y = 1
4x + 2y = −2

No Solution

Step-by-step explanation:

2x + y = 1

y = 1 - 2x

4x + 2(1 - 2x) = -2

4x +2 - 4x = -2

2 = -2

The statement is false, therefore there is no solution.

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
