step-by-step explanation:

graph b

step-by-step explanation:

one solution- graph a (clear intercepting point.)

no solution- graph b (they're parallel, there will never be a point of interception.)

infinite solutions- graph c (all points intercept.)

lr = 24

step-by-step explanation:

note that p is the midpoint of lr. to find the measurement of lr, set the equation:

lr = lp + pr

plug in the corresponding numbers to the corresponding variables:

lr = (15) + (9)

simplify:

lr = 24

24 is your measurement of lr.

vince wrote the sequence below.

1/3, 1, 5/3, 7/

which of the following explains whether the sequence is geometric?

the sequence is geometric because 2/3 was added to each term to get the next term.

the sequence is geometric because 3 was multiplied to each term to get the next term.

the sequence is not geometric because 2/3 was added to each term to get the next term.

the sequence is not geometric because 3 was multiplied to each term to get the next term.
