2. john's local coffee shop offers points to customers. each cup of coffee is worth 3 points. john
already has 20 points from an earlier promotion. if he goes to the coffee shop once a day for x
days, which of the following inequalities represents when he will have at least 50 points?
50-3x220
50-20 > 3x
20 + 3x2 50
50 > 20+ 3x

  20 + 3x ≥ 50

Step-by-step explanation:

After x days, John will have added 3x points to his total. The new total will be ...

  20 +3x

We want that value to be at least 50, so we use the symbol "greater than or equal to" to express that relationship:

  20 +3x ≥ 50

makes available a table of math symbols so you can choose the appropriate one to use in your expression. The number 2 is not the same as the symbol ≥. Using incorrect symbols makes it very difficult to tell what the intended problem is.

20 +3x ≥ 50

Step-by-step explanation:

since john already has 20 points this would be added to the points he is yet to receive

3 points if he goes to the shop once a day for x days

means 3x

because 3 points multiplied  by the number of days he went to the coffee shop

AT LEAST 50 means

≥50

now we can create the equation

20 + 3x ≥ 50

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
