F(-1) = -(-1) - 2 f(2) = -(2) - 2 f(4) = -(4) - 2
f(-1) = 1 - 2 f(2) = -2 - 2 f(4) = -4 - 2
f(-1) = -1 f(2) = -4 f(4) = -6
Answer:
58°
Step-by-step explanation:
We conclude that, if working at the same rate, to make 374 units, she needs to work for 17 hours.
<h3>
At the same rate, how many hours would she have to work to make 374?</h3>
We know that Mary makes 242 units of something in 11 hours of work, then her rate of work is:
R = (242 units)/(11 hours) = 22 units per hour.
Now, if she wants to make 374 units, then she needs to work for a time T, such that:
(22 units per hour)*T = 374 units.
Solving that linear equation for T, we get:
T = (374 units)/(22 units per hour) = 17 hours
We conclude that, if working at the same rate, to make 374 units, she needs to work for 17 hours.
