Answer:
Step-by-step explanation:
So
f(x) = -8x +11, for f(-4).
= -8(-4)+11
= 32 + 11
= 43
Answer:
Step-by-step explanation:
- The job can be completed by 7 people in 11 days
- The job is equivalent of 7*11 = 77 people*days
<u>After 3 days, job left:</u>
- (11 - 3)*7 = 56 people*days
This was completed by 7 - x people as x people left
<u>Time needed was 14 days, we have new equation:</u>
- 14(7 - x) = 56
- 7 - x = 4
- x = 7 - 4
- x = 3
As we found, 3 people left
Means, for every 1 input, there is 1 coresponding output
normally x is input and y is output in form (x,y)
so just look for the option(s) that has/have every first number repeat with only 1 2nd number
A. -7 repeats with 5 and -3, not a function
B. no repeats of first number (6,-8) and (-5,-8) are fine because first numbers don't repeat, das is funciton
C. no repeats, function
D. no repeats, function
answer is B,C,D
If each case weighs 24 pounds, then 1p=24 pounds. so if we're trying to find a function of weight, p=24c.
Example: When you have 2 cases, you plug in a 2 for c
p=24c
p=24(2)
p=48
So if you have two cases, it will total 48 pounds,
So that is why the equation is p=24c. Hope this helps!
