<span>f(x)=3x+8 and g(x)=6x+6
(f + g)(x) = f(x) + g(x)
= </span>3x+8 + (6x + 6) = 3x + 6x + 8 + 6 = 9x + 14<span>
</span>(f + g)(x) = <span> 9x + 14
</span>
(f + g)(-1) = <span> 9*-1 + 14 = -9 + 14 = 5
</span>
<span>(f + g)(-1) = 5</span>
Answer:
6 black and white photos
9 color photos
Step-by-step explanation:
1. black and white photo = $3
2. color photo = $2
find number of each photo that will give you at least 12 photos
1. $3*6 = $18
2. $2*9 = $18
3. $36 = 15 photos (6 black and white, 9 color)
Answer:
A negative correlation means one variable decreases as the other increases.
Answer:
After two days, 240 degrees was water.
Step-by-step explanation:
24 hours = 1 day
72 hr/24 hr = 3 days
Therefore, one full rotation takes 3 days.
1 rotation = 360 degrees
360 degrees/ 3 days = 120 degrees per day
120 degrees x 2 days = 240 degrees
240 degrees was watered after two days
132/5 = 26.4 is the answer
