Answer:
Lisa will not be able to feed both tanks the same amount of food.
Step-by-step explanation:
This question is incomplete, here is the complete question :
"Lisa pet shop has 2 fish tank . Tank A contains smaller fish who were fed 1 gram of food each per day. Tank B contains larger fish who are fed 2 gram each per day. If tank B contains 2/3 the number of fish Tank A contains,will Lisa ever feed both tanks the same amount of food."
Let the number of fish in tank A = f
Lisa fed 1 gram of food each per day = f × 1 = f
So,the number of fish in tank B = 
Lisa fed 2 gram of food each per day = 
If both the tanks are fed with same amount of food then
⇒ 3f = 4f
⇒ 3 = 4
But 3 ≠ 4
Therefore, Lisa will not be able to feed both tanks the same amount of food.

Answer:
f(-9) = 279
Step-by-step explanation:
f(x) = 4x^2 + 7x + 18
f(-9) = 4(-9)^2 +7(-9) + 18
= 4(81) - 63 + 18
= 324 - 63 + 18
= 279
Answer:
Step-by-step explanation:
The slope represents how much y is predicted to change on average for each 1 unit in x.
y = appraised value of a house in East Meadow County
x = # of rooms
1 unit of x = 1 additional room
1 unit of y = $1,000
slope = 19.79
Answer: Each additional room in a house in East Meadow County is predicted to increase the appraised value by 19.79 x $1,000 = $19,790, on average.
Note: Since we only sampled homes in East Meadow County, our regression equation is only good to predict appraised values in that county. So, our interpretation must include that fact.
