I hope this helps - it depends what you doing for it to be negative or nonnegative.. :)
Answer:
10/10
Step-by-step explanation:
The answer is ,c I took that same test and made a 95 on it
Since q+d=19, we can re-write this as d=19-q. Using the second equation 0.25q+0.1d=4 we can multiply both sides by 100. So we get 25q+10d=400. So now we can plug d=19-q into 25q+10d=400. So now we get, 25q+190-10q=400. Subtracting both sides by 190, we get 15q=210 and that q=14 plugging that in d=5

just substitute -8 for all x
process here:
f(x) = -3x + 7
f(-8)= -3(-8) + 7
