Line H is represented by the following equation: 2x + 2y = 8 What is most likely the equation for line K so the set of equations has infinitely many solutions?

x + 2y = 2
x + y = 4
2x + y = 6
x − y = 8

B

Step-by-step explanation:

Line H is represented by the equation:

And we want to find Line K such that the set of equations has infinitely many solutions.

Remember the three solution sets for linear equations:

From Line H, we can divide both sides by two. This yields the equivalent equation:

Therefore, the new equation and Line H are the same line. Thus, they will have infinitely many solutions.

The answer is B.

x = 10.1

step-by-step explanation:

all of the angles of a tirangle add up to 180º

180 - 65 = 115 (since we already know the value of one angle)

(2x + 7) + (8x + 7) = 115

(combins like terms) 10x + 14 = 115

(isolate the variable subtract 14 from both sides): 10x = 101

(find the variable divide both sides by 10): x = 101/10

x = 10.1

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:
