Let
x------> the number of weeks
we know that
-----> inequality that represent the situation
solve for x
Round to the nearest whole number
Answer:
Step-by-step explanation:
I assume the problem is to graph the lines. The easiest is to pick two values of x and calculate y for each line. For example:
21. y = -4x + 5 I'll randomly choose vales of 1 and 2 for x and calculate y:
(1, 1) and (2, -3)
Now mark those two points and draw a straight line through them. It is an equation of a straight line, so we know this will be correct.
22. Same process:
(1,6) and (2,7)
23. (1,0) and (2,-3)
24. (1,-4) and (2,-6)
=====================
These are shown in the attachment. What's also shown is the second method of producing the lines: Use a graphing program such as DESMOS to plot the equations. The points aren't needed - they are there to demonstrate that the first approach also works.
Answer:
True because it has different inputs and a function cannot have more than one of the same inputs.
All you have to do is multiply and add. 63 * 100 = 6,300. 5 * 10 = 5. 2 x 1 = 2. 6,300 + 50 + 2 = 6,352.
