Answer:
slope-intercept formula -----> Y2-Y1/X2-X1
Step-by-step explanation:
X1= 2 X2= 0
Y1= -4 Y2= -4
-4+4/0-2=0
If f={(-1,-3), (1,1),(2,3),(4,6)} and g={(-1,-1),(1,7),(4,3)} what is (f+g)(4)?
svet-max [94.6K]
Answer:
(f + g)(4) = 9
Step-by-step explanation:
We have that:
f = {(-1,-3), (1,1),(2,3),(4,6)}
this means that:
f(-1) = -3
f(1) = 1
f(2) = 3
f(4) = 6
and we also know that:
g = {(-1,-1),(1,7),(4,3)}
hich means that:
g(-1) = -1
g(1) = 7
g(4) = 3
Now we want to find:
(f + g)(4)
For the general case of two functions f(x) and g(x)
(f + g)(x) = f(x) + g(x)
Then:
(f + g)(4) = f(4) + g(4)
and we know both of these values, so we can just replace them:
(f + g)(4) = f(4) + g(4) = 6 + 3 = 9
Then we get:
(f + g)(4) = 9
Answer:
47.6 Degree Fahrenheit
Step-by-step explanation:
Given:
The Airplane is on the ground level at a temperature 59.7 Fahrenheit. Every 1,000 feet there will be drop in temperature which is 1.1 degrees Fahrenheit.
Initial Temp = 59.7 Fahrenheit
Distance Covered = 11,000 Ft
Explanation:
This means the Ground level is zero feet as the Airplane stands there.
Later, it climbs into the sky with 11,000 altitude.
That is 
For every 1,000 there is decrease in temperature of 1.1 degree Fahrenheit
Therefore, 11 times the temperature will decrease
That is 
12.1 Degree temperature will drop at 11,000 feet
Therefore
Temperature at 11,000 feet will be 
47.6 Degree Fahrenheit
