Answer:
Simplest function is f(x) = 2x - 1
Step-by-step explanation:
When a function has a zero, simply put, that point is where the graph goes through the x-axis. At this point, the y value is 0.
If a function has a 0 of 1/2, that translates to x = 1/2 and also (1/2, 0). That means that y = 0 when x = 1/2.
If x = 1/2 and is a zero, then x - 1/2 = 0 and 2x - 1 = 0 (notice that y = 0 here and solving for x would get you right back to x = 1/2).
The simplest function with a zero of 1/2 is
f(x) = 2x - 1
You know it is true that the zero is 1/2 for two reasons. First one is to set the right side equal to 0 and solve for x.
The second one is to graph the line y = 2x - 1 and see that it goes through the x axis at 1/2 where y = 0.
Answer:
42 hours
Step-by-step explanation:
Natalie needs to save a total of $479.58
She already saved $149.98
The amount left to save is
= 479.58-149.98
= 329.7
If she earns 7.85 dollars working per hour then the number of hours she can work to get $329.7 can be calculated as follows
= 329.7 / 7.85
= 42
Hence Natalie will work for 42 hours to meet her goals
11- \frac{1}{2} y=3+6x
Taking y to the other side;
11-3-6x= \frac{1}{2} y
8-6x= \frac{1}{2}y
Multiply each side by 2
16-12x=y
y=16-12x
