i think when it's say inequality...the answer is = 3 and 3.5
Answer:
Step-by-step explanation:
We have to find the points that are on the graph by finding the order pair (x, y) We are given the x value, so substitute x in the given equation f(x) and find y.
The graph is a line

Answer:
450 L
Step-by-step explanation:
Let x represent the number of liters of 70% solution needed. Then the amount of 15% solution needed is (550-x), and the total amount of acid in the mixture is ...
0.70x + 0.15(550-x) = 0.60(550)
0.55x + 82.5 = 330 . . . . simplify
0.55x = 247.5 . . . . . . . . . subtract 82.5
x = 450 . . . . . . . . . . . divide by 0.55
450 liters of 70% acid solution must be used.

Step-by-step explanation:
We assume that "make a function machine" means to program a spreadsheet or calculator to calculate values of the function for different inputs. Just about any graphing calculator or spreadsheet is a suitable platform. Attached is a screeenshot using the free Desmos online graphing calculator.
