24×3=72. 24 represents the days and 3 represents the fish added to the pond each day for 24 days.
If 80% of 90 were temerary, 75 would be the answer
Answer:The other endpoint is at (
−
4
,
3
)
Explanation:
The line segment passing through (
−
4
,
9
) and (
−
4
,
6
)
is a vertical line with the midpoint 3
units below the first point.
The other endpoint must be 3
further units below the midpoint
i.e. at (
−
4
,
(
6
−
3
)
Step-by-step explanation:
Answer for the first box: 38
Answer for the second box: -3
=========================================
Explanations:
To get the first answer, you plug in x = 0 to reflect were at the surface (height is 0)
38-3x = y
y = -3x+38
y = -3*0+38
y = 38
So the temperature at the surface is 38 degrees Celsius
--------------------
Each time x increases by 1 km, y decreases by 3 degrees C. How do we know? Because of the slope m = -3
Note how y = -3x+38 is in the form y = mx+b
m = -3 = -3/1 is the slope
slope = rise/run = -3/1
the "rise" being negative is really a fall or decrease. As we rise higher, the temperature goes down which is expected (It's colder higher up in the atmosphere)
(2,88)
(6,64)
(9,46)
(15,10)
first find y=mx+b
88=-6(2)+b
b=100
y=-6x+100
then plug for y and solve for x or vise versa.
