For find f(-2) of f(x)=7x+3, plug in -2 for x.
7(-2)+3=y
-14+3=y
y=-11
To find the rate, or the slope, you divide x/y. So 2/6 is 1/3. 3 over 9 is also 1/3. So the rate is 1/3. In rates you always divide, you don't mulitply or subtract or add to find the rate.
2 is greater than one and 3 and 4 and 5
Answer:
Letter D! That's the answer
Number of fish that are not carp = Total fish - number of carp fish
Since 1/3 of remaining fish which are not carp are sticklebacks , Number of sticklebacks =
<u>Now</u> ,
Number of tench = Total number of fish - (Number of carp + Number of sticklebacks)
Ratio of carp to sticklebacks to tench in the pond =
The largest area possible for the garden is 364.5 ft²
The width that will produce the maximum area is 13.5 ft
The length that will produce the maximum area is 27 ft
<h3>Area of a rectangle:</h3>
where
l = length
w = width
Only three sides need to be enclosed because one side is bordered by the parking lot. Therefore,
perimeter = l + 2w
54 = l + 2w
l = 54 - 2w
Therefore,
area = (54 - 2w)w
(54 - 2w)w = 0
w = 0 or 27
average = 27 /2 = 13.5
Hence, the max area is at w = 13.5 meters
Therefore,
l = 54 - 2(13.5) = 27 ft
length = 27 ft
width = 13.5 ft
Therefore,
area = 27 × 13.5 = 364.5 ft²
Therefore, the largest area possible for the garden is 364.5 ft²
