Answer:
She must sell as least 20 candles
Step-by-step explanation:
Sharon has 50 dollars
She makes 2 dollars per candle
Money in 50+2c
She needs at least 90
90≤ 50+2c
We need to solve this inequality
Subtract 50 from each side
90-50≤ 50-50+2c
40 ≤ 2c
Divide by 2
40/2 ≤ 2c/2
20 ≤ c
She must sell as least 20 candles

Answer:
<u>-2/-3.</u>
Step-by-step explanation:
Oh, this is easy!!
You need to find a point on the graph where it hits perfectly, for example, (2,-4), then use (-1,2).
Then use slope formula (y^2 - y^1/x^2 - x^1).
Plug in the X's and Y's.
Then, do 2 - (-4), and -1 - 2.
<u>You'd get -2/-3 :) </u>

Answer:
Step-by-step explanation:
<u>Take some reference points on the graph of f and g:</u>
- f(2) = 1, g(2) = 2
- f(4) = 2, g(4) = 4
- f(8) = 4, g(8) = 8
<u>According to the numbers above we can state:</u>
So the value of k is 2
