Sal is trying to determine which cell phone and service plan to buy for his mother. the first phone costs $100 and $55 per month for unlimited usage. the second phone costs $150 and $51 per month for unlimited usage. how many months will it take for the second phone to be less expensive than the first phone? the inequality that will determine the number of months, x, that are required for the second phone to be less expensive is . the solution to the inequality is . sal’s mother would have to keep the second cell phone plan for at least months in order for it to be less expensive.

a, b, c, d are correct.

step-by-step explanation:

we have g(x) = 3 and are required to find which option is a translation of g(x).

now, 'translation' is a transformation which means to shift the function in any direction and the general form of translation is g(x) + k, where k is any real number.

so, according to the options we see that all are correct as they satisfy the general form of translation.

also, it can be seen from the graph below that the function g(x) = 3 is shifted from its position in all the four options.

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.)
