Answer:
B
Step-by-step explanation:
A function can be graphed as a straight line, as long as it isn't vertical.
After solving the equation (work shown in image) your answer would be x > -2. I drew an image of how the number line should look at least similar to, using the solution.
*whenever you divide or multiply with a negative number reverse/flip the sign
< or > signs will always have an open circle
≥ or ≤ signs will have a closed/filled in circle
TIP: To know which way the arrow should point, look at the sign and think of it as an arrow.
< would have the arrow on the number point
this way: <-
or > which would have the arrow on the number line point this way: ->
5b + r = 30
the cost per item * the number of items sold = the profit
Answer
20
Step-by-step explanation:
well if you find a common denominator it would be 20 because 4 and 5 both go into 20 so
